AMENDMENT 1

CAN/ULC-S524

PUBLISHED February 2011


WHY• Clarifications• New requirements (Technology changes)

• Minor Corrections


SCOPE

• Voluntary Installations• Clarification• Installation of Fire Alarm Systems APPLIES


SCOPE

• Voluntary Installations• Scope note

This standard is intended to apply to both required and voluntaryfire alarm installations.


POWER BUSSES

• A very significant change• Concern is system survivability• Keeps with the philosophy of 4.2.7• As significant as Fault Isolators on Data

Communication Links


POWER BUSSES

• Is this a BIG change?

YES


POWER BUSSES

• A fault including a fault caused by fire, on a power buss could result in loss of that function on more than one fire zone.

• APPLIES TO MANY SITUATIONS INCLUDING:• POWER TO DISTRIBUTED AMPLIFIERS,• POWER TO 4- WIRE SMOKE DETECTORS,• POWER FROM ADDER POWER SUPPLIES TO STROBES.


POWER BUSSES

• Where a Power Buss Circuit serves more than 1 Floor

• A fault on one zone (open, short or ground)

• Shall not prevent normal operation of input or output field devices in more than one fire alarm zone.

• A class A circuit with fault isolation modules or equivalent shall be used.


FIBRE OPTICS

• Fibre Optics


FIBRE OPTICS

• Fibre Optics Cables shall be provided with mechanical protection similar to electrical conduit as in CEC Section 32


FIBRE OPTICS

• Fibre Optics Cables shall be• DEDICATED to fire alarm• Each junction access enclosure marked

“FIRE ALARM”


FIBRE OPTICS

• EXCEPTION:• Where multiple strand Fibre Optics

Cables are not dedicated to fire alarm,the fire alarm system shall continue to function despite any impairment of other systems that share the cable.


SMOKE CONTROL SYSTEMS

• Interface to or programming of smoke control systems cannot be checked or confirmed if the Smoke Control operation is not known.

• Documentation MUST be provided at the time of fire alarm installation.


SMOKE CONTROL SYSTEMS

• Sequence of smoke control operation.• Diagram of type and location of all

smoke control equipment (fans, dampers, etc.)

• Identify building areas smoke control serves.

• Documentation to be maintained on site.


SMOKE CONTROL PLANS


STAND ALONE SYSTEMS

• DELETED• Requirement to maintain

SYNCRONIZATION in the stand alone.


CONTROL OF VISIBLE SIGNALS

• When should Visible signals (strobes) turn off?


CONTROL OF VISIBLE SIGNALS

• Visible signals (strobes) are intended to supplement audible signals.

• Visible signals MUST turn off when “Signal Silence” occurs.

• Visible signals such as “Fire Do Not Enter” turn off at “Reset”.

DUCT SMOKE DETECTORS

Duct smoke detector sampling tubes MAY be mounted vertically

in the duct at the top.


CONNECTION TO A MONITORING SYSTEM

• Connections to a Fire Receiving Centre transmitter must be at a DEMARKATION TERMINAL BOX.

• The Demarcation Terminal Box • must have a minimum of 12 terminals,• must be located in the same room as the

fire alarm control unit,• must be labelled “FIRE ALARM

DEMARKATION


DEMARKATION TERMINAL BOX.


DEMARKATION TERMINAL BOX


CORRECTIONS

• TABLE 7 Corridor Spacing Allocation for Ceiling or Wall-Mounted Light Output for Wall-Mounted Visible Signal Devices CHANGED REFERENCE TO CLAUSE 5.4.5.13.

• TABLE 6 Light Output for Ceiling-Mounted Visible Signal Devices for Various Room Sizes CHANGED REFERENCE TO CLAUSE 5.4.5.10.


CORRECTIONS

• TABLE 5 Light Output for Wall-Mounted Visible Signal Devices for Various Room Sizes ADDED REFERENCE TO CLAUSE 5.4.5.7 AND DELETED WORD “DETECTOR FROM TITLE.

• FIGURE 3 Room Spacing for Wall-Mounted Visible Signal Devices CHANGED REFERENCE TO CLAUSE 5.4.5.9 ADDED REF TO 5.4.5.7.


SPOT TYPE FIRE DETECTOR SPACING FIGURE 9



RATED SPACING 9.1 m

Area of coverageRadius 0.7 x 9.1= 6.4m

In irregular shaped roomsall areas must be within 6.4m

Narrow rectangular areasmust fit within the circlebut if 3.1 m wide could have a spacing of 12.5m
