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 technical
reference manual.
10. Test the detector and verify sensitivity.

Testing
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.
Note:
Both the smoke element and heat element of the detector must
be tested.
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.
2. Test the detector’s smoke element using Smoke! In A Can (model
SM-200) canned smoke. Carefully follow directions on the can to
avoid damage to the detector.
3. Test the detector’s heat element using a heat gun while
maintaining a six-inch minimum. Use caution as excess heat can
damage the detector and detector housing.
