ADDITIONAL APPLICATION DATA
Refer to the application data document “Factory Installed Smoke
Detectors for Small and Medium Rooftop Units 2 to 25 Tons” for
discussions on additional control features of these smoke detectors
including multiple unit coordination. See Fig. 37.
SENSOR AND CONTROLLER TESTS
Sensor Alarm Test
The sensor alarm test checks a sensor’s ability to signal an
alarm state. This test requires 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.
Dirty Sensor Test
The dirty sensor test provides an indication of the sensor’s abil -
ity 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. A
field provided SD-MAG test magnet must be used to initiate a
sensor dirty test. The sensor’s Dirty LED indicates the results
of the dirty test as shown in Table 3.

IMPORTANT: 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.

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.
