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.
NOTICE
: 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.
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.
NOTICE
: 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.
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.
NOTICE
: 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.
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 7.
NOTICE
: 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
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.
NOTICE
: 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.
Changing the Dirty Sensor Test
By default, the dirty sensor 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.
