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 HAZARD
Failure to follow this caution may result in personnel
and authority concern.
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.
CAUTION
!
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 HAZARD
Failure to follow this caution may result in personnel
and authority concern.
This test places the duct detector into the alarm state.
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.
CAUTION
!
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
initiate a dirty sensor test and indicate its results.
OPERATIONAL TEST HAZARD
Failure to follow this caution may result in personnel
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 activate all automatic alarm responses.
CAUTION
!
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
ability 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. 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 2.
OPERATIONAL TEST HAZARD
Failure to follow this caution may result in personnel
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.
CAUTION
!
Table 2 – Dirty LED Test
FLASHES DESCRIPTION
1 0---25% dirty. (Typical of a newly installed detector)
2 25---50% dirty
3 51---75% dirty
4 76---99% dirty
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.
OPERATIONAL TEST HAZARD
Failure to follow this caution may result in personnel
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 auxiliary equipment from the
controller and notify the proper authorities if
connected to a fire alarm system.
