Maintenance

It is recommended that the detector be removed from its mounting base to facilitate easier 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 temporarily be out of service. Disable the zone or system undergo- ing maintenance to prevent unwanted alarms.

1.Remove the detector cover by placing a small bladed screwdriver in the side slot of the detector cover, twist- ing it slightly until the cover can be turned counterclock- wise for removal.

2.Vacuum the screen carefully without removing it. If fur- ther cleaning is required continue with Step 3, otherwise skip to Step 6.

3.Remove the screen by pulling it straight out (see Figure 2). Vacuum the inside.

4.Clean the vaned chamber piece by vacuuming or blow- ing out dust and particles.

5.To replace the screen, orient it so that the arrow on top aligns with the test module socket of the detector. Carefully push the screen onto the base making sure it fits tightly to the chamber.

6.Replace the cover by gently rotating it clockwise until it locks in place.

7.Reinstall the detector.

8.Notify the proper authorities that the system is back on line.
