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 7.
Table 7 — Dirty LED Test
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.
Changing the Dirty Sensor Test
By default, sensor dirty test results are indicated by:
• The sensor’s Dirty LED flashing.
• The controller’s Trouble LED flashing.
• 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).

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.
IMPORTANT: Failure to follow this ALERT can result in
an unnecessary evacuation of the facility.
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.
IMPORTANT: Failure to follow this ALERT can result in
an unnecessary evacuation of the facility.
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.
FLASHES DESCRIPTION
1
0-25% dirty. (Typical of a newly installed detector)
2
25-50% dirty
3
51-75% dirty
4
76-99% dirty
IMPORTANT: Failure to follow this ALERT can result
in an unnecessary evacuation of the facility.
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 opera-
tion, disconnect all auxiliary equipment from the control-
ler and notify the proper authorities if connected to a fire
alarm system.
