Maintenance
When cleaning is necessary, the sensing chamber of the
detector easily unsnaps for field cleaning and service.
To clean the detector:
1.
Remove the detector from the base.
2.
Insert a screwdriver in the small slot where the detector
cap connects to the detector body. See Figure 3.
3.
Pry the detector cap off the detector body.
4.
Squeeze the optical block chamber where the two arrows
point, labeled "squeeze here."
5.
Pull off the optical block chamber.
6.
Blow off the optical block base in the detector body using
clean compressed air.
7.
Snap a new optical block chamber in place. Make sure
you line up the two arrows on the block chamber with the
snaps on the optical block base.
8.
Connect the detector cap to the detector body by rotating
the cap clockwise until it snaps into a locked position.
9.
Install the detector onto the base.
Note:
To verify the effectiveness of the cleaning,
recalibrate the device and run a device maintenance
report. Refer to the control panel technical reference
manual.
10. Test the detector and verify sensitivity.
Test
NFPA 72 and CAN/ULC S537 require a calibrated sensitivity
test upon installation and following any modifications or
additions to the system. The detector can perform this test and
generate a system sensitivity report.
To test the detector:
1.
Before initial testing, remove the dust cover from the
detector and notify the proper authorities that the fire
alarm system is undergoing maintenance and will be
temporarily out of service.

canned smoke. Carefully follow directions on the can to
avoid damage to the detector.
