SENSOR AND CONTROLLER
TESTS
Sensor Alarm Test
The sensor alarm test checks a sensor’s ability to signal an
alarm state . This test requires that you use a field provided
SD-- MAG test magnet.
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.
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.
NOTICE
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
initiate and indicate an alarm state.
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.
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.
NOTICE
Controller Alarm Test Procedure
1. Press the controller’s test/reset switch for seven
seconds.
2. Verify that the c ontroller’s Alarm LED turns on.
3. Reset the sensor by pressing the test/reset switch for
two seconds.
4. Verify that the c ontroller’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.
OPERATIONAL TEST ALERT
Failure to follow this ALERT can result in an
unnecessary evacuation of the facility.
Pressing the controller’s test/reset switch for longer
than seven sec onds will put the duct detector into the
ala rm state and activate all automatic alarm responses.
NOTICE
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 dirt y sensor test provides an indication of the sensor’s
ability to compensate for gradual environmental changes.
A sensor tha t can no longer compensate for environmental
change s is considere d 100% dirty a nd re quires cleaning or
replacing. You must use a field provided SD--MAG test
magnet to initiate a sensor dirty test. The sensor ’s Dirty
LED indicates the results of the dirty test as shown in
Table 7.
OPERATIONAL TEST ALERT
Failure to follow this ALERT can result in an
unnecessary evacuation of the facility.
Holding the te st magnet a gainst the sensor housing for
more than seven seconds will put the duct detec tor
into the alarm state and activate all automatic alarm
responses.
