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 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 initi-
ate 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 initi-
ate 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.

IMPORTANT: OPERATIONAL TEST ALERT
Failure to follow this ALERT can result in an unnecessary
evacuation of the facility.
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.

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.
