SD--TRK4 Remote Alarm Test Procedure
1. Turn the key switch to the RESET/TEST position for
seven seconds.
2. Verify that the test/reset station’s Alarm LED turns
on.
3. Reset the sensor by turning the key switch to the
RESET/TEST position for two seconds.
4. Verify that the test/reset station’s Alarm LED turns
off.
Remote Test/Reset Station Dirty Sensor Test
The test/reset station dirty sensor test checks the test/reset
station’s ability to initiate a sensor dirty test and indicate
the results. It must be wired to the controller as shown in
Fig. 24 and configured to operate the controller’s
supervision relay. For more information, see “Changing
sensor dirty test operation.”

2. Verify that the test/reset station’s Trouble LED
flashes.
Detector Cleaning
Cleaning the Smoke Detector
Clean the duct smoke sensor when the Dirty LED is
flashing continuously or sooner if conditions warrant.
OPERATIONAL TEST HAZARD
Failure to follow this caution may result in personnel
and authority concern.
If the smoke detector is connected to a fire alarm
system, first notify the proper authorities that the
detector is undergoing maintenance then disable the
relevant circuit to avoid generating a false alarm.
CAUTION

2. Using a vacuum cleaner, clean compressed air, or a
soft bristle brush, remove loose dirt and debris from
inside the sensor housing and cover.
Use isopropyl alcohol and a lint--free cloth to remove
dirt and other contaminants from the gasket on the
sensor’s cover.
3. Squeeze the retainer clips on both sides of the optic
housing then lift the housing away from the printed
circuit board.
4. Gently remove dirt and debris from around the optic
