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 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.

SD-TRK4 Remote Alarm Test Procedure

1.Turn the key switch to the RESET/TEST position for seven seconds.

2.Verify that the test/reset station’s Alarm LED turns on.

3.Reset the sensor by turning the key switch to the RESET/TEST position for two seconds.

4.Verify that the test/reset station’s Alarm LED turns off.

Remote Test/Reset Station Dirty Sensor Test

The test/reset station dirty sensor test checks the test/reset station’s ability to initiate a sensor dirty test and indicate the results. It must be wired to the controller as shown in Fig. 24 and configured to operate the controller’s supervision relay. For more information, see “Changing sensor dirty test operation.”

!CAUTION

OPERATIONAL TEST HAZARD

Failure to follow this caution may result in personnel and authority concern.

If the test/reset station’s key switch is left in the RESET/TEST position for longer than seven seconds, the detector will automatically go into the alarm state and activate all automatic alarm responses.

!CAUTION

OPERATIONAL TEST HAZARD

Failure to follow this caution may result in personnel and authority concern.

Holding the test magnet to the target area for longer than seven seconds will put the detector into the alarm state and activate all automatic alarm responses.

Dirty Sensor Test Using an SD-TRK4

1.Turn the key switch to the RESET/TEST position for two seconds.

2.Verify that the test/reset station’s Trouble LED flashes.

Detector Cleaning

Cleaning the Smoke Detector

Clean the duct smoke sensor when the Dirty LED is flashing continuously or sooner if conditions warrant.
