2. Reset the sensor by removing the test magnet then holding
it against the sensor housing again until the sensor’s Alarm
LED turns off (approximately 2 seconds).
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. 57 and
configured to operate the controller’s supervision relay. For
more information, see “Changing sensor dirty test operation.”
Fig. 57 — Remote Test/Reset Station Connections
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. 58.
Fig. 58 — Sensor Cleaning Diagram
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.
Indicators
NORMAL STATE
The smoke detector operates in the normal state in the absence
of any trouble conditions and when its sensing chamber is free
of smoke. In the normal state, the Power LED on both the sen-
sor and the controller are on and all other LEDs are off.
IMPORTANT: Failure to follow this ALERT can result in
an unnecessary evacuation of the facility.
This test places the duct detector into the alarm state. Unless
part of the test, disconnect all auxiliary equipment from the
controller before performing the test. If the duct detector is
connected to a fire alarm system, notify the proper authori-
ties before performing the test.
IMPORTANT: Failure to follow this ALERT can result in
an unnecessary evacuation of the facility.
If the test/reset station’s key switch is left in the RESET/
TEST position for longer than seven seconds, the detector
will automatically go into the alarm state and activate all
automatic alarm responses.

IMPORTANT: Failure to follow this ALERT can result in
an unnecessary evacuation of the facility.
Holding the test magnet to the target area for longer than
seven seconds will put the detector into the alarm state and
activate all automatic alarm responses.
IMPORTANT: OPERATIONAL TEST ALERT
Failure to follow this ALERT can result in an unneces-
sary evacuation of the facility.
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.
