Maintenance
NOTE: Before performing maintenance on the detector, notify the
proper authorities and the central station 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, and follow this procedure exactly, referring to Figure 5.
1. Remove the detector housing from the base by twisting
counter-clockwise.
2. Remove the battery from the unit.
3. Wait 20 seconds. (To ensure proper power-down sequence, the
battery must be removed from detector for a minimum of 20
seconds before continuing to the next step.)
4. Remove the detector cover by turning counter-clockwise.
5. Vacuum the cover or use canned air to remove any dust or debris.
6. Remove the top half of the screen/sensing chamber by lifting
straight up (see Figure 5).
7. Vacuum or use canned air to remove any dust or particles that
are present on all chamber sections.
8. 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.
9. Replace the detector cover by placing it over the screen/sensing
chamber and turning it clockwise until it snaps into place.
