SENSOR AND CONTROLLER TESTS
Sensor Alarm Test
The sensor alarm test checks a sensor’s ability to signal an
alarm state. This test requires use of a field provided SD-MAG
test magnet.
SENSOR ALARM TEST PROCEDURE
1. Hold the test magnet where indicated on the side of the
sensor housing for seven seconds.
2. Verify that the sensor’s Alarm LED turns on.
3. Reset the sensor by holding the test magnet against the
sensor housing for two seconds.
4. Verify that the sensor’s Alarm LED turns off.
Controller Alarm Test
The controller alarm test checks the controller’s ability to initi-
ate and indicate an alarm state.
CONTROLLER ALARM TEST PROCEDURE
1. Press the controller’s test/reset switch for seven seconds.
2. Verify that the controller’s Alarm LED turns on.
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 initi-
ate a dirty sensor test and indicate its results.
DIRTY CONTROLLER TEST PROCEDURE
1. Press the controller’s test/reset switch for two seconds.
2. Verify that the controller’s Trouble LED flashes.
Dirty Sensor Test
The dirty sensor test provides an indication of the sensor’s abil-
ity to compensate for gradual environmental changes. A sensor
that can no longer compensate for environmental changes is
considered 100% dirty and requires cleaning or replacing. A
field provided 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 4.
Table 4 — Dirty LED Test
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 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 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.
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 authorities before performing the test.

Pressing the controller’s test/reset switch for longer than
seven seconds will put the duct detector into the alarm state
and activate all automatic alarm responses.

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.
FLASHES DESCRIPTION
1 0-25% dirty. (Typical of a newly installed detector)
2 25-50% dirty
3 51-75% dirty
4 76-99% dirty
IMPORTANT: Failure to follow this ALERT can 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 opera-
tion, disconnect all auxiliary equipment from the control-
ler and notify the proper authorities if connected to a fire
alarm system.

ties before performing the test.
