Changing the Dirt Sensor 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.
To Configure the Dirty Sensor Test Operation
1. Hold the test magnet where indicated on the side of
the sensor housing for approximately 60 seconds until
the sensor's Alarm LED turns on and its Dirty LED
flashes twice.
2. Reset the sensor by removing the test magnet and
then holding it against the sensor housing again for
approximately 2 seconds until the sensor's Alarm
LED turns off.
Remote Station Test
The remote station alarm test checks a test/reset station's
ability to initiate and indicate an alarm state.
