Maintenance
NOTE: Before performing maintenance on the detector, notify
the proper authorities that maintenance is being performed and
the system will be temporarily out of service. Disable the zone or
system undergoing maintenance to prevent any unwanted alarms.
Power must be removed from the detector before performing
maintenance of any kind.
1. Remove the detector cover by turning counterclockwise. (See
Figure 5.)
2. Vacuum the cover or use canned air to remove any dust or
debris.
3. Remove the top half of the screen/sensing chamber by lifting
straight up (Figure 5).
4. Vacuum or use canned air to remove any dust or particles that
are present on both chamber halves.
5. Replace the top half of the screen/sensing chamber by aligning
the arrow on the screen/sensing chamber with the arrow on the
housing. Press down firmly until the screen/sensing chamber is
fully seated.
6. Replace the detector cover by placing it over the screen/sensing
chamber and turning it clockwise until it snaps into place.
7. Reinstall the detector and test. (See the Testing section.)
8. Notify the proper authorities when the system is back in service.
