3. Conditions of Use

3.1 The Reliable WorkingLife (RWL) is 10 years for this device. Please refer to theattached please refer to the attached QSA Global Smoke detector ionizationchambers DSCA2C and DSCA3C source information sheet.

3.2 With regard to the information submitted in the section titled EnvironmentalQualification Testing, provided below is information specifically on vibration,shock, transportation, and temperature.

VibrationThe Thermal Ionization Device will be qualified to sinusoidal vibration testing inaccordance with MIL-STD-167-1, Type I from 4-33 Hz minimum. Contractrequirements may dictate a broader frequency range of 4-50 Hz. MIL-STD-167-1subjects the Unit Under Test (UUT) to a series of nine tests -- three tests in each principledirection.The first test is a low amplitude sweep across the frequency range to detect resonancewithin the UUT. The frequency range is swept at increments of 1 Hz and maintained at

each frequency for 15 seconds. The input is defined as nominal vibratory singleamplitudes of 0.010 inch from 4-33 Hz and 0.003 inch from 34-50 Hz. This correlates tovarying input accelerations, reaching a maximum of 1.1 ig at 33 Hz.The second test is a more stringent variable frequency test. The frequency range is sweptat increments of 1 Hz and maintained at each frequency for 5 minutes. The input isdefined as the nominal vibratory single amplitudes given below. The correspondinginput acceleration ranges are also given in Table 2 below.

Table 2 - Input Acceleration RangesFrequency Range Table Amplitude Acceleration (g)

(Hz) (inch)4 to 15 0.030 0.05 to 0.6916 to 25 0.020 0.52 to 1.2826 to 33 0.010 0.69 to 1.1134 to 40 0.005 0.59 to 0.8241 to 50 0.003 0.51 to 0.77

The third test for each principle direction is a resonant endurance. test. If a resonantfrequency is found during the previous two test, the UUT is subjected to a two-hour dwellat resonance and in accordance with the input table amplitudes identified in the variablefrequency test. If no resonance is found, the endurance will dwell at the highestfrequency tested during the previous tests. If multiple resonances are found, theendurance test will be divided between frequencies such that each resonant frequency istested for a minimum of 40 minutes and total test time is at least two hours.

ShockThe Thermal Ionization Device will be qualified to shock testing in accordance withMIL-S-901D. Input acceleration levels experienced during MIL-S-901D tests varysignificantly based on the shock apparatus used and the physical characteristics of theUUT. Anticipated input accelerations can range from 50g to hundreds of g's.

TransportationThe Thermal Ionization Device will meet or exceed the requirements of MIL-STD-81 OG,Method 514.6, Procedure I, Category 4 -- General Vibration for secured cargo oncommon carriers. The test exposes the UUT, while enclosed in actual shipmentpackaging, to random vibration levels according to typical measurement s extracted fromtransport trucks on U.S. highways. The duration of the test is 60 minutes per principleaxis relative to the packaging. The Power Spectral Density (PSD) curves for the testing,along with the Root Mean Square (RMS) acceleration, are as defined in Table 3 below.

Gams = 0.20 g GRMS = 0.74 g

TemperatureThe Thermal Ionization Device will be tested for high and low temperature integrity fortemperatures ranging from 0°C to 85°C. The test will be performed in accordance withprocesses of cyclical temperature MIL-STD-8 1OG, Methods 501.5 and 502.5,Procedures I and II. These conditions verify the high and low temperature integrity of theUUT under operation and storage.

Smoke detector ionization chambersDSCA2C and DSCA3C

DSCA2C and DSCA3CGeneral description

Both the DSCA2C and DSCA3C products incorporate a dualionization chamber of advanced design containing a singleradioisotope source producing ionization in both chambers. Thedesign was developed using a computer model to optimizeperformance characteristics. A performance test electrode isincorporated in the DSC.3C.

The design, manufacture and testing of the DSCA2C andDSCA3C ion chambers are managed within the scope of theQSA Global.Quality System which is certified by Lloyds RegisterQuality Assurance for compliance with BS EN ISO 9001:2000.(0)

The general construction was designed to meet the requirementsof Underwriters Laboratories Inc Standard UL 217(2) and EN54:part 7.(3) and both designs have been recognized by UL formany years.

For maximum corrosion resistance the electrodes and sourceholder are made of AISI 316 stainless steel, the support moldingof polypropylene and the insulators of polytetrafiluoroethyleneTeflonnT.

Details of the source are given in the data sheets 'Americium-241alpha foil and sources'(4) and 'Safety and Packaging'(5), bothavailable on request. In accordance with OECD requirements(6)the source activity is less than 37kBq (IktCi) Am-241. TheRecommended Working Life of the source is 10 years. TheANSI/ISO classification of the ionization chamber is C64646.

The units as supplied are assembled ready to mount on a suitableprinted circuit board using the pre-tinned tags provided. Nosource adjustment is required.

The DSCA3C's test electrode permits the checking not only ofthe operational functioning of the ion chamber but of allassociated electronic circuitry. When actuated, the electrodedisturbs the balance conditions to simulate the presence of smokeby an obscuradon of 4.00/%/Ft.

The design is compatible with commercially available integratedcircuits.

QSA Global expertise in the design and construction of ionchambers is long established and wide-ranging. A consultancyservice is available to assist in the design of systems using ionchambers.

Regulatory ComplianceQSA Global sources used in the detectors meet the regulatoryrequirements of most national authorities worldwide.

Specifically QSA Global sources comply with:

* European Norm EN 54(3)

* UK National Radiological Protection Board ('NRPB)criteria of acceptabilityv upon which UK legislationrelating to smoke detectors is based.

* Sources have been recognized by UnderwritersLaboratories Inc in compliance with Standard UL 217(-)as a component of smoke alarms and detectors.

Principle of Operation

The collector electrode is charged by an imbalance in theionization currents flowing in the inner and outer chambers, untilthese currents come into balance. In the absence of smoke orcombustion products, the balance potential remains constant,apart from small variations due to statistical fluctuation of theionization current.

When smoke enters the chambers the ionization currents change,that in the outer chamber more so than in the inner camber Thecollector electrode is then charged to a new balance potential.The change in potential is used to trigger an alarm circuit

The performance of the DSCA3C has been independentlyassessed in the following two studies:

• in smoldering smoke and fire tests by UnderwritersLabora~ories Inc.()

" in accordance with a Testing Program for AutomaticFire Alarm Equipment for Residential Use' by theDanish Research Centre for Applied ElectronicsF)

Copies of both reports are available on request.

Precautions and Recommendations

The ionization current is approximately 20pA. Precautions topreserve the insulation of the input connection path to theelectroni!s are critical for correct operation of the device. Inparticular the collector electrode and its connections must remainfree from contamination, e-g from solder flux or manual contact.The lead from the collector electrode to the detector circuitshould preferably be short and dear of the circuit board andother components

The chamber is shielded from external electric fields by its outercover. Suitable shielding should be provided for the associatedcircuit•7, because of the necessarily high impedance of the circuitconnected to the chamber collector electrode.

To improve corrosion resistance, the associated circuitry shouldbe sealed in a container, using a suitable sealant where thechamber terminals enter the chamber (avoiding sealant on thecollector electrode insulator).

Chambers intended for use at high altitudes may requireadjustment of the tripping level of the detector circuit foroptimum serssoitviyr.

Within reasonable limits, the balance potential remains relativelyunaffected by temperature, pressure, humidity and wind velocin,.

Source safety1. Classification of sealed sourceperformance

A radiation source must provide the highest possible integrity forits contents together with the mininum attenuation of theemitted radiation by the encapsulation materials which isconsistent with safety and the intended use. However, safety mustalways be the prime consideration.

The International Organization for Standardization have issued astandard (ISO 2919:1999) which establishes a system ofclassification of sealed radioactive sources based on testperformance- It also specifies production tests, rnarkiing and givesan example of a test report. Similar standards are ANSI/HPSN43.6-1997 published in the USA.

These standards, to quote from 1S02919, "...provides a set oftests by which the manufacturer of sealed radioactive sources canevaluate the safety of his products in use and by which the userof such sources can select types which are suitable for therequired application, especially where the release of radioactivematerial with consequent exposure to ionizing radiation isconcerned."

The suitability and safety of a source will depend on the in-ended

application and the environment of use of which there will be awide range. It is the customer's (users) responsibility to ensure thesource and its specification is suitable and safe for his particularapplication and environment of use. This applies to standardproducts and especially to non-standard products or custommade designs. The information given here is intended forguidance. It is recommended that the standards should beconsulted for detailed definitive information.The standard tests for the classification of sealed sourceperformance (ISO 2919) are given in Table 1. Examples of

\ additional tests which may be required for specific applicationsare given in the appendix to ISO 2919.

Quality controlQualir control of radiation can be divided into four main parts:

1. Routine production checks

Quality AssuranceRadiation sources are manufactured in accordance with a strictquality assurance program, details of which can be obtained onrequest.

Leakage and contamination testsStringent tests for leakage are an essential feature of radioactivesources production. They are based on ISO 9978. Some standardmethods used for testing radiation sources are listed below.

Wipe test IThe source is wiped with a swab or tissue, moistened with ethanolor water, the activity removed is measured.Limit: 200Bq(Limit USA: 5nCi)

Immersion test IIThe source is immersed in a suitable liquid at 50°C for at least 4hours and the activity removed is measured.Limit 200Bq(Limit USA: 5nCi)

Bubble test IIIThe source is immersed in water or a suitable liquid and thepressure in the vessel reduced to 13kPa (100=m Hg). No bubblesmust be observed.

Krypton emanation test VThe source is held under reduced pressure for 24 hours. Thecontent of the chamber is analysed for Krypton-85 byscintillation counting.Limit 370Bq

2. Special safety performance tests onprototypes

A radiation source must provide highest possible integritytogether with minimum attenuation of the required radiation bythe encapsulation materials. A compromise must sometimes bemade, particularly for alpha, beta and low energy photon sources.

Safety must always be the prime consideration. Standards for thetesting of sealed radioactive sources have been specified byISO.2919 and ISO.9978.

ISO.2919 'Sealed radioactive sources - Classification'1SO.9978 'Sealed radioactive sources - leak test methods'.

This classification system is modeled on USA standard US ANSIN43.6-1997 which also gives a number of comparable leak testmethods.

3. Measurements

Each source of batch of sources is checked to ensure that thestrengths of the sources supplied are within the limits specified.Wherever possible the results of these checks are indicated on thetest report. The methods of specifi-ng the strengths of sourcesare discussed under the heading specification on page El anddetails are included in the appropriate section of this catalog.

4. Test reports

A test report is supplied with each source or batch of sources.Where appropriate the following information is given:
