Smoke Testing the Detector
Smoke detectors should be tested in place annually using one of the
following methods:
A. Use Smoke! in a can
® (product number SM-200), a canned
aerosol simulated smoke and follow the directions on the can.
B. Use the following steps to test the detector with smoke:
1. Hold a smoldering punk or cotton wick close to the
smoke entry openings.
2. Gently direct the smoke into the detector for 20 seconds
or until an alarm is indicated.
Be sure to extinguish the smoke source after testing! The
detector LED should stay on and an alarm should be indicated at the
control panel. Use the system reset switch to reset the detector.
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 simulta-
neously turning the detector counterclockwise 15 degrees. See
Figure 7.
