MFP Range Installation / Maintenance Instructions DFU0500100 Rev: 4 Page 1

These instructions are general and cannot be considered to cover every aspect of fire alarm installation.

We recommend you read BS 5839: Pt 1: 1988 "Fire Detection and Alarm System s for Build ings" (available

at you r local reference library or from the BSI).

No r esponsibility can be accepted by th e man ufacturers or d istributors of this range of fire panels for any

misinterpretation of an instruction or gu idance note or for the compliance of the system as a w hole.

Contact the Fire Officer concerned with the property at an early stage in case he has any special

requirem ents. We strongly recomm end that a suitably qualified and comp etent person is consulted in

connection w ith the d esign of the Fire Alarm system.

The manu facturers policy is one of continuous improvem ent and we reserve the right to make changes

to produ ct specifications at ou r d iscretion and withou t pr ior notice. E&OE.

1. This equipment must only be installed and maintained by a suitably skilled or technicallycompetent person.

2. This equipment is a piece of class 1 equipm ent and MUST BE EARTHED.

3. To meet th e requ irements of BS 5839 Part 1 1988 Amend men t N 1 (Effective Jan . 1991) manual callpoints mu st still operate w hen any detectors are removed from their bases. This is man datory whether

or not the detectors have locking or shorting dev ices. To comply with this directive either the man ual

call points must be w ired before the d etectors, incurring extra installation expense, or detector bases with

diod es fitted mu st be used to ensu re continu ity when d etectors and call points are mixed.

The MFP range of panels will operate in this way an d w ill give a distinct fault indication w hen a

head is removed.

4. If you connect the battery leads in reverse you w ill blow the battery fuse and you RISK DAMAGINGTHE PAN EL. The fau lt is factory detectable and you WILL BE CHARGED FOR THE REPAIR.

5. If the Battery/ Power Supp ly fault light comes on wh ilst the Green Mains On light is lit then itusu ally means that the battery is either d ischarged or faulty (see page 9 inside for details).

PLEASE READ THESE INSTRUCTIONS CAREFULLY BEFORE

CONTROL PANEL

The fire panel must be sited internally, in an area where it isreadily accessible by staff on du ty and th e fire brigade. Thearea should be clean and dry and you should take intoaccount any likelihood of tampering or vandalism. Theambient light and soun d levels should allow the status of the

indicators to be clearly seen and the internal sounder to beheard . Full details can be found in BS 5839: Pt1: 1988: Section15.3 "Fire Detection and Alarm Systems for Buildings".

SOUNDERS

All sound ers must be polarised. Unpolarised sounders willshow a sound er fault.

The most common soun ders are bells and electronic sound -ers.Motorised sirens MUST NOT be used on these panels . Thesame type of sound er must be used throughou t the buildingand it must be d istinctive so that the sound associated w ith afire alarm is easily recognised.

The minimum sound level is 65 dB or 5 dB above any

background noise likely to persist for longer than 30 seconds.The fire alarm mu st be aud ible in every par t of the building.For sleeping accommodation the sound level should be 75 dBat the bedhead if sleeping peop le with normal hearing are tobe wakened.

Four sound er circuits are provided. Not all need be used , butat least two circuits should be connected with at least onesound er on each. Sound ers should be wired in approximatelyequal numbers on each circuit .

MANUAL CALL POINTS

Manual Call Points should be sited on all exit routes espe-cially on landings and staircases and by final exit doors, with

a maimu m d istance from any p lace in the building to a CallPoint of 30 metres, (less distance in high risk areas). Theyshould ideally be sited 1.4 metres above the floor and in aconspicuous and easily reached position. Any nu mber of callpoints can be connected on each zone.

Important: Many call points are now supp lied w ith a resistoralready fitted. This can be determined by measuring with agood qu ality Ohm meter. The call point should normally meas-ure open circuit, and 470 or 680 ohm s when activated. If the callpoints are not of this type then a series resistor must be con-nected in series with th e call point in order to ensure that analarm cond ition will occur . See figure 1 for fitting diagram .

SMOKE AND HEAT DETECTORS

Up to 20 heat or smoke detectors can be fitted on each zone.

Smoke Detectors: There are two typ es of smoke detector,Ionisation and Optical. Ionisation are generally quickest atdetecting a clean burning fire. Optical are quickest at

detecting sm ouldering fires. Neither one is better than theother in all circumstances. Some Fire Authorities will onlyallow one kind and you shou ld check with the Fire Officer.Do not site smoke detectors in draughts. Siting of thedetectors d epends on m any factors and BS5839: Pt1: 1988"Fire Detection and Alarm Systems for Buildings" should beconsulted for full details of spacing, etc.

Dirt, du st, smoke, steam, water vapour and condensationwill affect the detectors, causing false alarms an d the needfor frequent cleaning. Under these conditions, the use of heatdetectors should be considered (see below). If in doubt,consult the Fire Officer. Note:Building w ork causes adverseconditions. If possible, remove all detectors from site un tilwork is completed to avoid contamination.

Heat Detectors: These are used in p laces where sm oke detec-tors are not practical, such as kitchens and boiler rooms. Thereare two kinds, Fixed Temperature and Rate of Rise. FixedTemperature Detectors are used where sudden rises in tem-perature which would cause alarms are common, such as inkitchens. Rate of Rise Detectors are used elsewhere as theygenerally respond faster than Fixed Temperatu re Detectors.

BATTERIES

For the emergency stand-by pow er supp ly, two good quality12V sealed lead acid ba tteries (connected in series) should beused. They should be of a type that have at least four yearslife und er norm al conditions.

The capacity of the batteries used will depend on the re-quired stand -by time (See 'Panel Specification', page 10, forstand-by times).

For battery connection d etails, see 'Installation - Second Fix',page 5. Always dispose of used batteries according to thebattery manufacturers instructions.

Important:This range of panels features a sophisticated ba tterymonitoring circuit which, instead of monitoring the currentbeing passed through the batteries, actually detects their con-dition. Consequently, a discharged battery or one with d eterio-rat ing cells will show a BATTERY/ POWER SUPPLY FAULT.Test w ith brand new, fully charged batteries.

CABLE TYPES

Sound ers mu st be wired in cable complying with, forexample, BS6207 (MICC or pyro). Detectors may be wiredin cable complying with, for example, BS6004 (PVC) orBS6207. Ensure you comply with BS5839 Pt1 regardingsiting, installation and choice of cables.

NOTES ON THE OVERALL DESIGN

Decide on the p osition of all parts and mark the plansaccordingly. Get the Fire Officer to check them to ensu re anyspecial requirements he may have are complied with (he hasthe r ight to r efuse a fire certificate until he is satisfied).

Note: To fully comply w ith BS5839 Manual Call points m ust

still operate when any of the Detectors are removed. Thiscan be accommodated by wiring Call Points first or by usingdetector bases with continuity diod es fitted. Some manufac-turers supply bases with integral diodes.

Note: Never spu r off any d etector or sound er cable run , asthe spu r w iring w ill not be m onitored correctly.

Note: Resistors are not included with the panel but areavailable from electronic comp onent sup pliers. Failure toinclude this resistor will cause the p anel to show a short circ-uit fault ind ication wh en the call point is operated. This also

app lies to any other form of switch used to trigger the detect-or circuits. This panel will work with resistance values from470 to 680 ohms fitted. The resistors must be rated half watt.

N.B. It is possible to disable the short circuit = fault conditionfor each zone so that a short circuit will cause a fire condition(see page 7 for further d etails).

IINSTALLATION - FIRST & SECOND FIX

FIRST FIX

Run cables and fix the smoke and heat d etector bases andcall point s. Fit sound ers.

Take the control panel out of its box and u nd o the two screwsat the top u sing the key provided in the accessory pack.

Hinge the lid dow n 180 and remove the earth connection.Locate the connector plug(s) on the main printed circuitboard. Grasp the w ires to the plug(s) firmly and pu ll theconnector off the board . Then h inge the lid back 90 an dlift the fron t panel off.

The front p anel may be removed from site until work iscompleted if it is likely to get dam aged .

Fix the base of the fire panel securely to the wa ll using themou nting holes provided (see 'A', figure 3). The mou nt-ing holes are suitable for use w ith No. 8 round head orcountersunk woodscrews. Assess the condition andconstruction of the wall and use a suitable screw fixing.

Any d ust created du ring the fixing p rocess must be kept

out of the fire panel, and great care mu st be taken not todam age any wiring or comp onents.

All mains wiring should be p rovided in accordance withthe cu rrent edition of the IEE Wiring Regs, 16th. Ed. (BS7671, 1993) or in accordance with the r elevant n ationalwiring ru les.

The general requirement for the m ains supp ly to thisequ ipment is fixed wiring, using th ree core cable, not lessthan 0.75mm 2 or a suitable three conductor system, fedfrom an isolating switch fuse spur, fused at 3A. Thisshou ld be m arked "FIRE ALARM: DO NO T SWITCH OFF"and sh ould be secure from unau thorised operation.

The mains connection is mad e inside the fire pan el to thefused mains terminal block only. Connection mu st not bemad e to the mains supp ly using a plug and socket. The

ma ins supp ly shou ld be exclusive to the fire panel. (Fulldetails can be fou nd in BS5839: Pt1: 1988 section 15.3. "FireDetection and Alarm Systems for Build ings").

The wiring of the pan el should be carefully p lanned beforestarting the job. Always ensure th at if a knockout is removed,that th e hole is filled with a good quality cable gland.

Plan and route all of the wiring as indicated in Figure 3 bythe dotted lines.

All external wiring brou ght into the pan el should be

adequ ately insulated with PVC, PTFE, Neoprene or oth erfire resistant / retardent material.

Do not use an insulation tester (Megger) with anydetectors, soun ders, continuity d iodes or control equip-

ment of any kind connected as the 500 volt test voltagewil l destroy all of these devices totally.

On some smoke d etector bases removing the head opencircuits on e connection, therefore to test cont inuity of circuitit may be n ecessary to link out these bases. N.B. If cont i-nuity diod es are to be used in d etector bases then they mu stbe fitted in th e correct orientation as shown in the Detectorbase d etails (see Figure 4).

Next, connect all sounders and plug in all detectors. Checkthe wiring continuity with a mu lti-meter (do not test withan insulation tester (Megger).

Ensure that Manual Call Points have resistors fitted (seepage 2), otherwise a short circuit fault w ill occur in stead ofa Fire cond ition.

When you are sure all connections are firm with n o insulationtrapp ed and no bare wires, replace the front of the pan el andre-attach the relevant loom connectors.

Make sure that the earth wire is connected back up.

Next, power th e system up by connecting the batteries. Todetermine the type and size of batteries required, refer topages 2 and 10.

Conn ect the batteries in series as show n in Figur e 5.Always be sure of the connections before you make themas incorrect connection will blow th e battery fuse (F5) andmay d amage the panel.

Postion the batteries in the pan el as shown in Figure 6.Once the batter ies are connected, close up th e panel, fit thetwo lid screws and then energize the mains sup ply. Thepan el should n ow be in the Norm al mode. If not see

Now test th e system is fully opera tional ( See 'Testing ThePanel', page 5).

If the number of zones of the panel is to be increased, refer to therelevant zone kit for installation instructions.

space for batteries

The diode mu st be connected so that it is shorted ou t bythe internal connections of the head w hen th e head is inplace, and pr ovides a path for the current in the loop w henthe head is removed. Incorrect fitting will not causedamage but will cause malfunctions of the system. (Seetroubleshooting - page 9)

DO NOT connect the w iring into the terminal block in the

panel until you have tested the pan el.

Do not leave any p art of the fire alarm system w here itmay become du sty or damp (due to any building worksuch as p lastering, paint ing, carpet fitting,etc) as this willresult in possible malfunctions, including false alarms.

SECOND FIX

Only to be carried ou t when all b uildin g w ork is com-plete and no more dust wi ll be raised.

Check the pan el is isolated from the m ains. Remove thebatteries and lid of the panel to avoid accidental dam age

whilst connecting the wires.Having checked the w iring and panel remove the End ofLine Devices (small plastic covered circuit board w ithflying leads) and Resistors from the term inal block andinsert them across the terminals of the last detector and thelast sound er respectively in each circuit.

Use the shorting link inthe accessory pack

Do not connect any wires except th e mains feed.

Hook on the p anel front and plug the connector onto thecircuit board (PL4). The red wire in the plug loom goes tothe right hand side as marked on th e circuit board.

Install batteries of suitable capacity in the bottom of the pan eland connect them in series using the link w ire(s) provided.Connect the batteries to the circuit board via the red (positive)and black (negative) battery leads. (See 'Battery Connection',page 4). The BATTERY/ POWER SUPPLY FAULT light w ill

light and the WARNING BEEPER will sound. Incorrectconnection wil l blow the battery fu se (F5) and MAY DAM-AGE THE PANEL.

Connect the mains wiring and tu rn the mains supp ly on.The MAINS ON light w ill light, the BATTERY/ POWERSUPPLY FAULT light will go out and the WARN INGBEEPER will silence, provid ing the batteries are not flat. Ifthe batteries are completely discharged or if they areinferior but still working, the battery fault circuit w ill stillshow a fault check this using new batteries. Please notethat a fu lly charged 24 Volt battery w ill measu re 26 to 28Volts and th at if it measures less than 25 Volts it is almostcompletely flat. If a battery m easures less than 21 Volts it is

either totally exhausted or may have a faulty cell.A battery m easur ing less than 21 Volts is un likely torecharge prop erly and should be replaced. The batterymon itoring circuit will show a BATTERY/ POWER SUPPLYFAULT, which, if it does not cease, means th at the batteriesare faulty.

WITH THE KEYSWITCH AT NORMAL

The MAINS ON light is lit. No other lights are lit. Nosound ers are sound ing. The pu sh buttons are inoperative.

TURN THE KEYSWITCH TO ARM CONTROLS

This allows the pu sh buttons to be used by an authorisedperson bu t does not otherwise affect the p anel.

Press RESET / TEST/ SCROLL. All the Zone Fault Lightswill light mom entarily and then all the Zone Fire Lights.

The green Mains On led will remain lit.

All the other lights will NOT light.

TEST THE POWER SUPPLY MONITORING CIRCUIT

Switch off the Ma ins. The BATTERY/ POWER SUPPLYFAULT lamp will light, the MAINS ON light w ill extin-guish, and the WARNING BEEPER will sound.

Press SILENCE ALARM/ FAULT SOUNDERS and theWARNING BEEPER will silence but t he MAINS/ BAT-TERY FAULT light will remain lit.

Reconnect the m ains and after a short time the p anel willrevert to normal.

Disconnect the Battery. After a short time the MAINS/BATTERY FAULT light w ill light and the WARNINGBEEPER will sound.

Reconnect the battery and after a short time the p anel willrevert to normal (i.e. only the gr een MAINS lights on).

Note

1) This test should be carried out w ith a set of new andfully charged ba tteries deter iorated cells will show afault even wh en connected and charged up .

2) If good bu t comp letely discharged cells are used th eMAINS/ BATTERY FAULT light w ill stay on for severalminutes until the battery obtains sufficient charge.

TEST THE SOUNDER MONITORING CIRCUIT(S)

DO NOT carry out th is test with any r ed FIRE light lit assoun der fuse(s) could blow ( F1, F2, F3 or F4 ). Make su re asmall end of line resistor (colour code blue, grey, red, gold)is connected across each of the sound er circuits on term i-na ls (5 & 6, 7 & 8, 9&10, 11&12).

Short the soun der term inals 5 & 6 and keep them shorted.

The SOUN DER FAULT light will light and the WARN INGBEEPER will sound.

Press SILENCE ALARM / FAULT SOUNDERS and theWARNING BEEPER will silence but th e SOUNDERFAULT light w ill stay on .

Remove the short an d th e panel w ill revert to normal.

Open circuit the sound er terminals 5 & 6 by disconnectingone leg of the end of line resistor. The SOUN DER FAULTlight will light an d th e WARNING BEEPER will sound .Press SILENCE ALARM / FAULT SOUNDERS and theWARNING BEEPER will silence but th e SOUNDERFAULT light w ill stay on .

Remake th e circuit and the pan el will revert to norm al.Repeat the tests for the other sounder circuits.

TEST THE DETECTOR MONITORING CIRCUITS

Make su re an End of Line Device (EOLD) is connected

across each p air of Detector Zon e term inals ( 13 & 14, 15 &

16, etc.). This dev ice is polarised and the red wire m ust be

connected to Zon e +Ve and the black wire to Zone -Ve.

Five cond itions can exist on the d etector circuits.

1. Normal condition:Current flows round the detector

loop via the EOLD to monitor the wiring. Detectors and

call point s are connected in p arallel across the line.

2. Open Circuit Fault: The wiring is broken at some p ointand the monitoring current cannot flow.

3. A Head Removed Fault condition:where a head has

been removed from its base leaving a diode in circuit.

(Required on those systems where Man ual Call points are

wired in mixed order w ith detectors and are required to

operate when a detector is removed)

4. Short Circuit Fault: A short circuit exists at some point

and too much m onitoring current flows.

5. Fire condition:A p artial short exists and the m onitoring

current increases but n ot enough to show a short circuit

fault. Most smoke detectors make a p artial short w hen

they are triggered bu t manu al call points and oth ernorm ally open sw itches need to have 470 or 680 ohm

resistors connected in series in order to give a partial

short. (Check - Resistor may be included in Call Point as

supplied).

TEST FACILITIES (SEE FIGURE 7 FOR LINK POSITIONS)

Whilst the panel is in any of the following test setups theGENERAL FAULT led w ill be lit continu ously, the War n-ing Sound er will be active and cannot be silenced. TheAuxiliary Fire and Fault expansion ou tpu ts are disabled.

ONE MAN TEST (NON-LATCH TEST) FACILITY (OMT)

This is a non-latching test facility which allows man ual callpoints and autom atic smoke detectors to be tested and toreset autom atically. To set this facility link the plu gmar ked OMT on PLK1 and th e adjacent LED will light an dthe WARNING BEEPER will sound and cannot be silenced.When the pan el is triggered the alarm soun ders w illoperate for one second and will silence for eight secondsapp roximately before resound ing. During the latter periodthe d etector circuits are reset. This cycle will continu e un tilthe cause of the alarm is removed by the sm oke clearingfrom a detector, or the call poin t being reset. When testingis complete, remove the link.

SOUNDER WALK TEST FACILITY (SWT)

This test facility aids checking the sound ers in each area ofthe building w ithout continuous an noying activation. Toset this facility link the plu g marked SWT on PLK1 andthe adjacent LED will light and the fault beeper will soundand cannot be silenced. This facility activates a cycle wherethe alarm sound ers operate for 1 second and then remainsilent for 10 seconds ap proximately. When testing iscomplete, remove the link.

CONFIGURATION FACILITIES

DELAYED SOUNDERS

This facility sets a delay of 30 seconds from the pan el being

triggered from any zone to th e activation of the alarmsound ers. Used in clubs etc wh ere the nuisance or paniccaused mu st be avoided. This delay can be overridden bymomentary activation of the EVACUATE button, which isautom atically armed du ring this delay period even w iththe keyswitch in the N ormal p osition.

AUX 24V +VE

This outpu t is a regulated but unm onitored outpu t fusedat 1A (F6). With PLK2 (ad jacent relay) linked in p osition Athis outpu t is continu ous. If PLK2 is linked in p osition Bthen the outp ut is present when the panel is normal but isswitched off when the relay is activated.

This facility can be used to prov ide a fail-safe outpu t, that"switches off" wh en the sou nd ers are activated or if thepow er to the panel fails. Note that any load provided bythis outpu t increases the quiescent drain on the pan elssup ply w hich in turn affects the stand -by time of thesystem.

It is not intend ed to su pp ly door release systems (see below)

VOLTAGE FREE RELAY CONTACTS

These single pole relay outputs available via 2 (normallyclosed), 3 (common), and 4 (normally open) in the base

connections change over w hen th e sound ers are activated.They must not be used to switch mains p otentials, being

rated at 30vD.C. and 1.0A.Note about Holding Magnets(Magnetic Door Retainers)

BS5839 Pt1 1988 states that dev ices which d raw curren t &

hence would red uce the battery stand-by time (minimum24 Hou rs plus 1/ 2 hour of full alarm load) mu st not be

fitted. We therefore recomm end that either:-

1) 24 Volt hold ing magnets shou ld use a separate 24 Voltpow er supp ly un der control of the panel. Ideally the

separate sup ply shou ld be of a "Hold off" type thatrequires very little control current

2) 240 Volt hold ing magnets shou ld be used , in wh ich case

a separate ma ins pow er switching 24 Volt coil relay,pow ered from the panel, should be used.

Special polarised relays and PSUs are available for

connecting to either the sounder circuits, or to AuxiliaryFire Outp uts (see page 8), to allow control of Door Releasesystems.

This facility must only be used w ith approval ofthe Fire o fficer.

During th e delay period panel lights will ind icatethe triggered Zone(s) and the Fault Beeper willsound with an u rgent tone. The pan el can beSilenced then Reset du ring the d elay periodbefore the Sound ers are activated.

To set this facility link the p lug m arked DS on PLK1.

AUXILIARY EXPANSION PLUG

This range of panels provides A uxiliary Expansion Inp utand Outp uts to interface with external equipment. TwoFire outpu ts and a Fault outpu t are provided. These are ofopen collector type. These outp uts can be disabled via theDISABLE function (see page 6).

A "Class change" input is provided that will activate thealarm sound er outpu ts from an external command .

Connections are mad e via the Ancillary Connections "A" to

"F" in the base of the p anel. The connections are t hentransferred to PL5 (adjacent relay) on th e ma in PCB byFF574X Expansion Loom (not included )

The Ancillary Connections "A" to "F" are as follows:

AUXILIARY FIRE OUTPUT 1 (A)

This outp ut is activated when the alarm sound ers areactivated in a Fire condition.

AUXILIARY FIRE OUTPUT 2 (B)

This outp ut is activated in a Fire condition, whether th ealarm sou nd ers are activated or n ot. i.e. it is activatedimmed iately w hen a Fire condition is detected, even in the

delayed sound ers mode. This outpu t remains activated ina Silenced Fire state, un til the panel is Reset.

AUXILIARY FAULT OUTPUT (C)

This outp ut is activated in any Fault condition. When allFaults are cleared then th e Fault outpu t is deactivated.

EXTERNAL SOUNDER ACTIVATE ("CLASS CHANGE") (D)

This norm ally open inp ut w hen shorted to 0v activates therelay to activate the Alarm Sound er circuits. When theshort is removed the soun ders are reset.

No p anel indication is given d uring the sou nd er activation.

0V SUPPLY (E) AND 24V (F)

Sup ply outp uts for use with the above.APPLICATIONS FOR AUXILIARY INPUTS AND OUTPUTS

The outpu ts are typically used to drive relays external tothe pan el. The relays may for examp le be used to controlventilation system s, gas valves, doo r release systems etc .The External Sounder Activate may be used to interface toother pan els or may be controlled by a time switch to givea mom entary warn ing of a timed event via the alarmsound ers throughou t a building (check with the Fireofficer that th is is perm issible).

There is no restriction on th e choice of relays other than ifdriven d irectly from the pan el they mu st have a 24v coiland the current mu st not exceed th e Auxiliary outpu tcapability (see page 10), and if they ar e switching m ainspotentials that the load is suitably isolated from the FirePanel d rive circuits.

If the coil curren t is der ived from the panel it will affectthe stand-by time of the system. The worst case is that ofthe Fault relay which will be energised for the w hole timethe mains sup ply has failed.

CIRCUIT EXAMPLES

The circuit below shows an example of a general arrange-ment wh ere all outputs and inpu ts are used.

FIRE PANEL INTERCONNECTION

Show n below is an example man y MFP Panels may beinterconnected so that an y pan el that is triggered into analarm state can then activate the alarm sound ers on all theother p anels via a common 2 wire connection. The wiringbetween the p anels must hav e less than 100 impedancebetween the furthest points and no other connectionsshould be mad e to the pair.

In ad dition each pan el has a relay connected to Au x. Fire 2in ord er to switch a Strobe light (for examp le) from a localsup ply. In this case the light w ould only be illuminated ifthat particular panel was in an alarm state, but not iftriggered externally. All the Alarm Sound ers are Silencedfrom the triggered pan el only. After Silencing th e lightstays lit un til the pan el is Reset.

The mains must be isolated whi lst the lid is open.

MANUAL CALL POINTS AND NORMALLY OPEN SWITCHES

CAUSE A SHORT CIRCUIT FAULT WHEN TRIGGEREDA call point resistor has n ot been fitted in series at eachcall point or sw itch. A resistor MUST be fitted as th eBritish Stand ard requ ires short circuit monitoring facilityfrom 1st Janu ary 1990.

MANUAL CALL POINTS, ECONOMY HEAT DETECTORS, OR SMOKEDETECTORS TRIGGER, BUT DO NOT CAUSE A FIRE CONDITION

Either the wrong value call point resistor has been fittedin series at the call point or d etector or a resistor is alreadyfitted inside . If you h ave fitted a resistor try shorting itout and re-testing the device. To check the zone is OK,remove all wiring from the p anel and re-insert an EOLD(End of Line Device) to give a norma l cond ition. Then

simu late a fire cond ition on th e zone w ith a 470 to 680Ohm resistor. If the zone goes into fire the device un dertest may be ou t of specification.

RESET / TEST / SCROLL BUTTON DOESN'TRESET THE PANEL FROM FIRE CONDITION

Press SILENCE first.

RESET / TEST / SCROLL BUTTON STILL DOESN'T RESET THE PANEL

Either a call point is triggered in w hich case replace theglass or if an older bi- metal heat detector has triggered,wa it for it to cool dow n and r eset itself.

A smoke d etector may be faulty and will not unlatch, in

wh ich case the LED on th e detector may not be lit andyou can only find the offending device by followinglogical tests. Start by removing the wiring and refittingthe EOLD in the panel to prove the pan el is OK. Thenreconnect the w iring an d EOLD, and set the panel in theOne Man Test (OMT) mod e (page 7). Starting at the en dof the line, remove each d etector in tu rn. When you reachthe faulty d evice the p anel will remain reset. Remove theOMT link w hen th e test is complete.

THE BUZZER SOUNDS AND THEGENERAL FAULT LIGHTS IS LIT STEADILY

The pan el has been left in a test mod e. Remove the link(s)on PLK1.

PERMANENT BATTERY/POWER SUPPLY FAULT

1. Is the MAINS ON light illum inated ? If not, check themains su pp ly and fuse (adjacent to Transformer).

2. Check the battery su pp ly (RED lead to +Ve term inal,BLACK lead to -Ve terminal). If the battery lead s havebeen connected the wrong w ay round the battery fuse(F5) will blow bu t a perm anent p ower fault may h avebeen caused wh ich CANN OT be reset. The fault is factorydetectable and is not covered by the w arranty.

Consult your d ealer.

3. Check tw o 12 Volt batteries of the relevan t size areconnected in series .

4. Check the wiring loom is pu shed on prop erly to PL4.

5. Check the transformer leads are pu shed on to the tagson the transformer prop erly.

6. If the MAINS ON & BATTERY/ POWER SUPPLY Fau ltlights are still lit, the batteries are heav ily discharged or

have failed - try a new pair, even new batteries have beenknow n to fail.

PERMANENT ZONE FAULT

N.B. The number of pulses of the Zone Fault light ind icatesthe fault type. 1 Pulse = Short Circuit, 2 = Head r emoved,

3 = Open Circuit. If the light is steady th en the zon e isDisabled (see page 6).

Disconnect the relevant zone completely and refit theEOLD at the panel. If the fault condition clears then ther eis a w iring fault. Double check and refit the w iring andEOLD on th e zone and trace the fault with considerationfor the type of fault indicated.

A common fault is a detector badly seated in a base, thathas not prop erly made connection.

If the fault is a Head removed and all the heads are fittedthen check that a resistor has not been fitted by mistake inplace of the EOLD. N.B. Bad ly fitted h eads w ithou t diod es

fitted will show an O.C Fault.INCORRECT RESPONSE WHEN HEAD REMOVED

Zone Fault led show s 3 pu lses = Op en circuit. The continu-ity diod e is either not fitted, is fitted in r everse or is faulty.If this is the case then Manu al Call poin ts after the re-moved detector will not respond w hen activated.

Refit correctly (See fig 4, page 4) or rep lace the d iode.

If no fault is indicated w hen a head is removed and thediod e is fitted correctly then ther e is an incompa tibilityproblem w ith the pan el and head s or the cables. Consultyour dealer.

PERMANENT SOUNDER FAULT

Check the Sound er fuses ( F1, 2, 3 & 4 ) on th e pcb an drep lace if necessaryx.

Check the correct end of line resistor (6800 Ohm s; blue, grey,red , gold) has been fitted. Disconnect the relevant zone fromthe term inal block and refit the end of line resistor only. If thefault condition clears there is a wiring fau lt.

BUTTONS DON'T WORK

Turn the keyswitch to ARM controls and press SILENCEALARM/ FAULT SOUN DERS and then RESET / TEST /SCROLL. If the fault persists, check the plug a ssemblyfrom th e keyswitch (PL3) is seated correctly on pcb.

PROCESSOR FAULT LIGHT LIT

Accomp anied by perm anent Fault beeper tone.

This state indicates that the panels microprocessor hasfailed to execute its programme correctly and that a safetycircuit has operated to restart the program me. This can becaused by sudd en interruption of all power, high poweredinterference (e.g. lightning str ike) or misconnection orfailure of circuit boards and peripheral equipm ent.

To stop this fault warning tu rn th e keyswitch to ARMcontrols and press RESET / TEST / SCROLL.

If the Processor Fau lt light comes on aga in, check theconnections between the system circuit boards, and thatthe p ower su pp ly is not faulty. If this fault persists then thepan el must be return ed to you r dealer for investigation.

N.B. If the microprocessor is restarted (after a fault orwh en the panel is pow ered up ) then any functions thatwere disabled w ill now be enabled . (A fail-safe feature).

IF ANY FAULT CONDITION PERSISTS CONSULT YOUR DEALER

The battery stand-by times are guidelines only based on the above

conditions. Additional loads that increase the quiescent current in the

normal state and sounder loads must be considered when calculating

stand-by time. Batteries in poor condition greatly reduce stand-by time.

SYSTEM INSPECTION

This is a requirement of BS5839 Pt 1: 1988 "Fire Detection and Alarm Systems for Buildings"

and should be carried out by person(s) responsible for supervising the system.

DAILY INSPECTION

Check the MAINS ON light is lit. Check no other lights are lit or sound ers operating. No-

tify any faults to th e installer.

WEEKLY TEST

Turn the Keyswitch to ARM CONTROLS and press RESET / RESOUND / TEST ZONE

LAMPS. Check that all zone lights show and that the WARNING BEEPER sounds. Operate

a call point or sensor to test the fire alarm. Check that the alarm sounders operate. Reset

the fire alarm by p ressing SILENCE and then RESET / RESOUN D / TEST ZON E LAMPS

(Two people may be needed for this test). Each w eek test a d ifferent zone (if applicable).

Also use a d ifferent call point or sensor for each test, so that all call points and sensors are

tested in rotation. A building plan detailing the call point / sensor location is recom-

mended . Check all call points and sensors and verify that non e is obstructed in any way.

QUARTERLY TEST

Check all previous Log Book entries and verify that rem edial action has been taken. Visu-

ally inspect the bat tery and its connections. Operate a call point or sensor in each zone to

test the fire alarm as in the weekly test above. Remove the mains supp ly and check that the

battery is capable of supp lying the alarm sound ers.

ANNUAL TEST

As for the weekly and qu arterly tests but check every detector, call point , sounder and all

auxiliary equipment for correct operation.
