B. Smoke Entry: 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.
For AD355, smoke entry testing should be performed immediately following the magnet test. Magnet test initiates an approximately 10 minute period when
the detector's signal processing software routines are not active. Failure to first perform the magnet test will introduce a time delay before the detector alarms.
C. Direct Heat Method (Hair dryer of 1000-1500 watts). SD355T and AD355 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 approxi-
mately 12 inches from the detector in order to avoid damaging the plastic housing. The detector will reset only after it has 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 and
returned for repair.
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 cham-
ber. 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 SD355T
and AD355 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.
