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 de-
scribed in the GEMINI 501 manual. Using the bowl shaped applicator,
apply aerosol until the panel alarms. Additionally, canned aerosol simu-
lated 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 In-
dustries 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.
CAUTION
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.
For AD355, smoke entry testing should be performed immediately fol-
lowing 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 approximately 12 inches from the detector in order to avoid dam-
aging the plastic housing. The detector will reset only after it has suf-
ficient 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.

Fcc s tatement
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired operation.
NOTE:
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used
in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installa-
tion. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try
to correct the interference by one or more of the following measures:
– Reorient or relocate the receiving antenna.
– Increase the separation between the equipment and receiver.
– Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
– Consult the dealer or an experienced radio/TV technician for help.
c Leaning
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 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.
