System Sensor 2151 and 2151T Low Profile Photoelectric Plug-in - Manual (Page 2)

CAUTION
Canned aerosol simulated smoke (canned smoke agent) formulas will vary by
manufacturer. Misuse or overuse of these products may have long term ad-
verse effects on the smoke detector. Consult the canned smoke agent manufac-
turer’s published instructions for any further warnings or caution statements.
D. Direct Heat Method (Hair Dryer of 1000-1500 watts) 2151T only
A hair dryer of 1000-1500 watts should be used to test the thermistors. Di-
rect 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.
Notify the proper authorities that the system is back on line.
Detectors that fail these tests should be cleaned as described under MAIN-
TENANCE and retested. If the detectors still fail these tests, they should be
returned for repair.

SPECIAL NOTE REgARDINg SMOkE DETECTOR gUARDS
Smoke detectors are not to be used with detector guards unless the combina-
tion has been evaluated and found suitable for that purpose.
CAUTION
Dust covers are an effective way to limit the entry of dust into smoke detector sens-
ing chambers. However, they may not completely prevent airborne dust particles
from entering the detector. Therefore, System Sensor recommends the removal
of detectors before beginning construction or other dust producing activity.
Be sure to remove the dust covers from any sensors that were left in place dur-
ing construction as part of returning the system to service.
CAUTION
Smoke detectors are not to be used with detector guards unless the combina-
tion has been evaluated and found suitable for that purpose.

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 un-
wanted 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 2151T.
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.
