Cleaning
It is recommended that the detector be removed from
its mounting base to facilitate cleaning. The detector is
cleaned as follows:
NOTE:
Before removing the detector, notify the proper
authorities that the smoke detector system is
undergoing maintenance and will be temporarily
out of service. Disable the zone or system under-
going maintenance to prevent unwanted alarms.
1. Remove the detector cover by prying away the four
side tabs with a small-bladed screwdriver, and then
pulling the cover from the base.
2. Vacuum the screen carefully without removing it. If
further cleaning is required continue with Step 3, oth-
erwise skip to Step 7.
3. Remove the screen/chamber cover assembly by pull-
ing it straight out (see Figure 4).
4. Clean the chamber by vacuuming or blowing out dust
and particles.
5. Replace the sensing chamber cover, aligning the
arrow on the top with arrow on the printed circuit
board.
6. To replace the screen, place it over the chamber
assembly, turning it until it snaps into place.
7. Replace the cover using the LEDs to align the cover
and then gently pushing it until it locks into place.
8. Reinstall the detector.
9. Test the detector as described in TESTING.
10. Reconnect disabled circuits.
11. Notify the proper authorities that the system is back
on line.
