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 3.
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 3 – 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.
Changing the Dirt S ensor Test
By default, sensor dirty test results are indicated by:
S The sensor’s Dirty LED flashing.
S The controller’s Trouble LED flashing.
S 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.
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.
