Dirty Sensor Test Procedure
1. Hold the test magnet where indicated on the side of the sensor
housing for two seconds.
2. Verify that the sensor’s Dirty LED flashes.
CHANGING THE DIRT SENSOR TEST
By default, sensor dirty test results are indicated by:
• The sensor’s Dirty LED flashing.
• The controller’s Trouble LED flashing.
• The controller’s supervision relay contacts toggle.
The operation of a sensor’s dirty test can be changed so that the
controller’s supervision relay is not used to indicate test results.
When two detectors are connected to a controller, sensor dirty test
operation on both sensors must be configured to operate in the
same manner.
To Configure the Dirty Sensor Test Operation
1. Hold the test magnet where indicated on the side of the sensor
housing for approximately 60 seconds until the sensor’s
Alarm LED turns on and its Dirty LED flashes twice.
2. Reset the sensor by removing the test magnet and then hold
-
ing it against the sensor housing again for approximately
2 seconds until the sensor’s Alarm LED turns off.
REMOTE STATION TEST
The remote station alarm test checks a test/reset station’s ability 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 station’s
ability to initiate a sensor dirty test and indicate the results. It must
be wired to the controller as shown in Fig. 42 and configured to
operate the controller’s supervision relay. For more information,
see “Changing the Dirty Sensor Test.”

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 con
-
tinuously or sooner, if conditions warrant.
1. Disconnect power from the duct detector then remove the
sensor’s cover. (See Fig. 43.)

NOTICE: OPERATIONAL TEST NOTICE
Failure to follow this NOTICE may result in an unnecessary
evacuation of the facility.
Changing the dirty sensor test operation will put the detector
into the alarm state and activate all automatic alarm responses.
Before changing dirty sensor test operation, disconnect all aux
-
iliary equipment from the controller and notify the proper au
-
thorities if connected to a fire alarm system.
NOTICE: OPERATIONAL TEST NOTICE
Failure to follow this NOTICE may result in an unnecessary

Changing the dirty sensor test operation will put the detector
into the alarm state and activate all automatic alarm responses.
Before changing the dirty sensor test operation, disconnect all
auxiliary equipment from the controller and notify proper au

thorities if connected to a fire alarm system.
NOTICE: OPERATIONAL TEST NOTICE
Failure to follow this NOTICE 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 auto
-
matically go into the alarm state and activate all automatic
alarm responses.
NOTICE: OPERATIONAL TEST NOTICE
Failure to follow this NOTICE 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.
NOTICE: OPERATIONAL TEST NOTICE
Failure to follow this NOTICE can result in an unnecessary
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 generat
-
ing a false alarm.
