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 undergoing 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, otherwise skip to Step 7.
3. Remove the screen/chamber cover assembly by pulling 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.

LaSer SaFetY inFOrmatiOn
This smoke detector does not produce any hazardous laser radiation and is
certified as a Class 1 laser product under the U.S. Department of Health and
Human Services (DHHS) Radiation Performance Standard according to the
Radiation Control for Health and Safety Act of 1968.
Any radiation emitted inside the smoke detector is completely within the pro-
tective housings and external covers. The laser beam cannot escape from the
detector during any phase of operation.
The Center of Devices and Radiological Health (CDRH) of the U.S. Food and
Drug Administration implemented regulations for laser products on August 2,
1976. These regulations apply to laser products manufactured after August 1,
1976. Compliance is mandatory for products marketed in the United States.
CAUTION
Use of controls, adjustments, or performance of procedures other than those
specified in this manual may result in hazardous radiation exposure.
