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.

!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.

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.

!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

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 2.

!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.
