1. Hold the test magnet in the magnet test area as shown in Figure 3.

2. The sensor should alarm the panel.

Two LEDs on the sensor are controlled by the panel to indicate sensor
status. Coded signals, transmitted from the panel, can cause the LEDs
to blink, latch on, or latch off. Refer to the control panel technical docu-
mentation for sensor LED status operation and expected delay to alarm.

B. Smoke Entry: Aerosol Generator (Gemini 501 or other UL lised devices)

The GEMINI model 501 aerosol generator can be used for smoke entry
testing. Other UL listed smoke generating devices may be used as well.
Set the generator to represent 4%/ft to 5%/ft obscuration as described in
the GEMINI 501 manual. Using the bowl shaped applicator, apply aero-
sol 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 De-
tector 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.

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 SK-Acclimate, smoke entry testing should be performed immediately
following the magnet test. Magnet test initiates an approximately 10 min-
ute 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). SK-Photo-T and

SK-Acclimate 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 had 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.

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 push-

ing it until it locks into place. Make sure that the thermistors do not be-
come bent under the cover on the SK-Photo-T and SK-Acclimate 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.
