alarms.
All sensors must be tested after installation and
periodically thereafter. Testing methods must satisfy the
Authority Having Jurisdiction (AHJ). Sensors offer
maximum performance when tested and maintained in
compliance with NFPA 72.
The sensor can be tested in the following ways:
A. Smoke Entry test: Aerosol Generator (Gemini 501)
The GEMINI model 501 aerosol generator can be used
for smoke entry testing. Set the generator to represent
4%/ft to 5%/ft obscuration as described in the GEMINI
501 manual. Using the bowl shaped applicator, apply
aerosol until the panel alarms. Additionally, canned
aerosol simulated smoke (canned smoke agent) may be
used for smoke entry testing of the smoke detector. Tested
and approved aerosol smoke products are the Smoke
Detector Tester model 25S available from Home
Safeguard Industries and Chekkit Smoke Detector Tester
models CHEK02 and CHEK06 available from SDi.
When used properly, the canned smoke agent will cause
the smoke detector to go into alarm. Refer to the
manufacturer
’
s published instructions for proper use of
the canned smoke agent.
Canned aerosol simulated smoke (canned smoke agent)
formulas will vary by manufacturer. Misuse or overuse of
these products may have long term adverse effects on the
smoke detector. Consult the canned smoke agent
manufacturer
’
s published instructions for any further
warnings or caution statements.
B. Direct Heat Method (Hair Dryer of 1000-1500 watts)
YT202T only
A hair dryer of 1000-1500 watts should be used to test the
thermistors. Direct the heat toward either of the two
thermistors, holding the heat source approximately 12
inches from the detector in order to avoid damaging the
plastic housing. The detector will reset only after it has
had sufficient time to cool. Make sure both thermistors
are tested individually.
A sensor that fails any of these tests should be cleaned as
described under CLEANING, and retested. If the sensor
fails after cleaning, it must be replaced.
When testing is complete, restore the system to normal
operation and notify the proper authorities that the system
is back in operation.
CLEANING
Before removing the detector, notify the proper
authorities that the smoke detector system is undergoing
maintenance and will be temporarily out of service.
Disable the zone or system undergoing maintenance to
prevent unwanted alarms.
1.
Remove the sensor to be cleaned from the system.
2.
Remove the sensor cover by pressing firmly on each
of the four removal tabs that hold the cover in place.
3.
Vacuum the screen carefully without removing it. If
further cleaning is required continue with Step 4,
otherwise skip to Step 7.
4.
Remove the chamber cover/screen assembly by
pulling it straight out.
5.
Use a vacuum cleaner or compressed air to remove
dust and debris from the sensing chamber.
6.
Reinstall the chamber cover/screen assembly by
sliding the edge over the sensing chamber. Turn until
it is firmly in place.
7.
Replace the cover using the LEDs to align the cover
and then gently pushing it until it locks into place.
Make sure that the thermistors do not become bent
under the cover on YT202T models.
8.
Reinstall the detector.
9.
Test the detector as described in TESTING.
10.
Reconnect disabled circuits.
11.
Notify the proper authorities that the system is back
on line.
