Attaching and Removing the Detector
To remove the detector from the mounting base, grasp
the detector and turn it counterclockwise approximately 15
degrees. The detector should snap off of the mounting
base.
To remove the detector from the mounting base when
the detector/base lock is used, insert a small screwdriver
into the locking tab slot on the side of the base and press in
while simultaneously turning the detector counterclockwise
15 degrees. See Figure 6.
Attach the smoke detector to its mounting base as
follows:
- Line up the raised tab on the side of the detector with the
arrow on the mounting base. See Figure 4.
- Insert the smoke detector into the base and turn
clockwise approximately 15 degrees. It should snap
firmly into place.

Testing the Detector Sensitivity
The detector provides a sensitivity test that allows you to
check the detector sensitivity using a test magnet and the
LED indicator on the detector as follows:
1. Hold the test magnet up to the raised TEST letters on
the top of the detector for 2 seconds. See Figure 5.
Once the test starts, the alarm LED flashes one to nine
times.
2. Count the number of times the LED flashes and use the
following table to determine the status of the detector
sensitivity and what action to take, if any.
After the test:
If the sensitivity is within limits and all other tests pass,
the detector goes into alarm and must be reset from the
control panel.
If the sensitivity is not within limits or an unserviceable
hardware fault has been detected, the detector LED
flashes every 1.5 seconds until the detector is serviced.
