Remote Station Test
The remote station alarm test checks a test/reset station’s abili-
ty to initiate and indicate an alarm state.
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 sta-
tion’s ability to initiate a sensor dirty test and indicate the re-
sults. It must be wired to the controller as shown in Fig. 55 and
configured to operate the controller’s supervision relay. For
more information, see “Changing sensor dirty test operation.”
Dirty Sensor Test Using an SD-TRK4
1. Turn the key switch to the RESET/TEST position for two
seconds.
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.
1. Disconnect power from the duct detector then remove the
sensor’s cover. See Fig. 56.
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.
4. Lift the housing away from the printed circuit board.
5. Gently remove dirt and debris from around the optic plate
and inside the optic housing.
6. Replace the optic housing and sensor cover.
7. Connect power to the duct detector then perform a sensor
alarm test.
NOTICE
OPERATIONAL TEST ALERT
Failure to follow this ALERT can result in an unnecessary
evacuation of the facility.
This test places the duct detector into the alarm state. Un-
less part of the test, disconnect all auxiliary equipment from
the controller before performing the test. If the duct detec-
tor is connected to a fire alarm system, notify the proper au-
thorities before performing the test.
NOTICE
OPERATIONAL TEST ALERT
Failure to follow this ALERT can result in an unnecessary
evacuation of the facility.
Holding the test magnet against the sensor housing for
more than seven seconds will put the duct detector into the
alarm state and activate all automatic alarm responses.

If the smoke detector is connected to a fire alarm system,
first notify the proper authorities that the detector is under-
going maintenance, then disable the relevant circuit to
avoid generating a false alarm.
