3. Reset the sensor by pressing the test/reset switch for two
seconds.
4. Verify that the controller’s Alarm LED turns off.
DIRTY CONTROLLER TEST
The dirty controller test checks the controller’s ability to initiate a
dirty sensor test and indicate its results.
Dirty Controller Test Procedure
• Press the controller’s test/reset switch for two seconds.
• Verify that the controller’s Trouble LED flashes.
DIRTY SENSOR TEST
The dirty sensor test provides an indication of the sensor’s ability
to compensate for gradual environmental changes. A sensor that
can no longer compensate for environmental changes is consid
-
ered 100% dirty and requires cleaning or replacing. A field pro
-
vided SD-MAG test magnet must be used to initiate a sensor dirty
test. The sensor’s Dirty LED indicates the results of the dirty test
as shown in Table 2.
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 DIRTY 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 until the sensor’s Alarm LED turns on and its Dirty
LED flashes twice (approximately 60 seconds).
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 two seconds).
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. 24 and configured to
operate the controller’s supervision relay. For more information,
see “Changing the Dirty Sensor Test.”

IMPORTANT: Failure to follow this notice may result in per
-
sonnel and authority concern.
Pressing the controller’s test/reset switch for longer than seven
seconds will put the duct detector into the alarm state and acti
-
vate all automatic alarm responses.
IMPORTANT: Failure to follow this notice may result in per
-
sonnel and authority concern.
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.

DESCRIPTION
1
0-25% dirty. (Typical of a newly installed detector)
2
25-50% dirty

51-75% dirty
4
76-99% dirty
IMPORTANT: Failure to follow this notice may result in per
-
sonnel and authority concern.
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.
IMPORTANT: Failure to follow this notice may result in per
-
sonnel and authority concern.
This test places the duct detector into the alarm state. Unless
part of the test, disconnect all auxiliary equipment from the con
-
troller before performing the test. If the duct detector is connect
-
ed to a fire alarm system, notify the proper authorities before
performing the test.
