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.
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 using Smoke-In-A-Can (model SM-200) canned
smoke. Carefully follow directions on the can to avoid damage to
the detector.
