OPERATIONAL TEST HAZARD
Failure to follow this caution may result in personnel
and aut hority 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
connec ted to a fire alarm system, notify the proper
authorities before performing the test.
CAUTION
!
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 T
est
The dirty controller test checks the controller ’s a bility to
initiate a dirty sensor test and indicate its results.
OPERATIONAL TEST HAZARD
Failure to follow this caution may result in personnel
and aut hority concern.
Pressing the controller’s test/reset switch for longer
than seven seconds will put the duct detector into the
ala rm state and activate all autom atic alarm responses.
CAUTION
!
Dirty Controller Test Procedure
S Press the controller’s test/reset switch for two seconds.
S Verify that the cont roller’s Trouble LED flashes.
Dirty Sensor T
est
The dir ty sensor test provides an indic ation of the sensor’s
ability to compensate for gradual environmental changes.
A sensor that can no longer compensat e for environment al
change s 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.
OPERATIONAL TEST HAZARD
Failure to follow this caution may result in personnel
and aut hority concern.
Holding the test magnet against the sensor housing for
more than seven seconds wil l put the duct detector
into the alarm state and activate all automatic alarm
responses.
CAUTION
!
Table 2 – Di rty LED Te st
FLASHES DESCRIPTION
1 0--- 25% dirty. (Typical of a newly installed detector)
2 25---50% dirty
3 51---75% dirty
4 76---99% dirty
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.
OPERATIONAL TEST HAZARD
Failure to follow this caution may result in personnel
and aut hority concern.
Changing the dirty sensor test operation will put the
detector into the alarm state and activate all automatic
alarm responses. Before changing dirt y sensor t est
operation, disconnect all auxiliary equipment from the
controller and notify the proper authorities if
connected to a fire alarm system.
CAUTION
!
Changing the Dirty Sensor Test
By defaul t, 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 toggl e.
The operati on of a sensor’s dirty test can be change d 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 (approximatel y 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 T
est
The remote station alarm test checks a test/reset station’s
ability to initiate and indicate an alarm state.
OPERATIONAL TEST HAZARD
Failure to follow this caution may result in personnel
and aut hority 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 t he
test. If the duct detector is connected to a fire alarm
system, notify the proper authorities before
performing the test.
