Installer Compensation Reset
Cleaning or replacement of the smoke sensor chamber changes the
background signal/noise of the detector; this requires the drift com-
pensation be reset. Compensation trouble is one of the faults indi-
cated when the LED indicator is OFF while the sounder is chirping.
1. Remove batteries, then short the detector battery contacts for 5
seconds to power down unit.
2.Replace batteries to power up unit while pressing the test but-
ton.
3.The tamper switch must not be pressed.
4.The LED will flash when 5 seconds has elapsed. Release the test
button within 2 seconds of the LED flash.
5.The LED will flash every 2 seconds for 1 minute. During this
period, the detector must be mounted.
Allow an additional 2 minutes for the detector to make back-
ground level checks.
6.Test the detector to verify normal operation.
5. Test Unit
NOTE: The central monitoring station (if used) should be notified
3V CR123A
prior to the test being generated. This will prevent a false alarm and
Insert
an unnecessary response from the central monitoring station.
First
Initiate test by pressing the test button for 5 seconds minimum.
Alarm activation is indicated by the flashing LED, the sounder, and
transmission of the alarm signal to the control panel. The detector
restores to normal when the test button is released.
NOTE: Allow a minimum of 20 seconds after power up and , after
test, alarm or tamper restore activations. Do not use test button
when smoke is present.
NOTE: If the detector is in one of the following states when a test is
initiated; it will not enter an alarm state.
• Tamper, (detector not installed on mounting plate)
• Compensation Trouble
• Other internal faults that could prevent a smoke or heat alarm.
PULL
NOTE: Smoke sensitivity of installed detectors can be measured
DOWN
without removal or an alarm being generated using the FSD-100
Tab
Smoke Detector Test Meter.
To test the unit using the FSD-100, set the test meter up to read
devices as per the instructions supplied. Depress the test button on
Backplate
the smoke detector for 1 second and release.
Tabs
NOTE: If the test button is held for 5 seconds or longer, an alarm

Move the test meter over the center of the detector, wait until you
hear the test meter beep, remove the unit and the information can
be immediately reviewed. Please see the instructions supplied with
the FSD-100 Smoke Detector Test Meter for more information.
6. Device Enrollment
The 6 digit serial number located on the back of the smoke detector
housing must be enrolled into the alarm control panel with Installer
programming. Refer to the receiver Installation Manual for details.
For placement tests remove detector from backplate for one second
(tamper) then reattach. Wait at least 30 seconds for test result before
activating again.
