!CAUTION
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.
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.
!CAUTION
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.
Dirty Controller Test Procedure
S Press the controller’s test/reset switch for two seconds. S 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
!CAUTION
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.

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.
!CAUTION
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.
Changing the Dirty 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 until the sensor’s Alarm LED turns on and its Dirty LED flashes twice (approximately 60 seconds).
2.Reset the sensor by removing the test magnet then holding it against the sensor housing again until the sensor’s Alarm LED turns off (approximately 2 seconds).
Remote Station Test
The remote station alarm test checks a test/reset station’s ability to initiate and indicate an alarm state.
!CAUTION
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.
