Sensor and Controller Tests
SENSOR ALARM TEST
The sensor alarm test checks a sensor’s ability to signal an alarm
state. This test requires the 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 initiate
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 initiate 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 ability
to compensate for gradual environmental changes. A sensor that
can no longer compensate for environmental changes is consid -
ered 100% dirty and requires cleaning or replacing. 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 6.
