Testing and Maintenance
Procedures
Before testing, notify the proper authorities that the smoke detector system
is undergoing maintenance and will be temporarily out of service. Disable
the zone or system undergoing maintenance to prevent unwanted alarms.
After a detector is set into alarm by one of the following test methods and
the alarm activating device is removed from the detector, the system
should be reset at the control panel before testing any additional detectors.
After all testing is complete and the system is returned to its normal
configuration, notify the proper authorities that the system is back in
service.
All detectors must be tested after installation and periodically thereafter.
Testing methods must satisfy the authority having jurisdiction. Detectors
offer maximum performance when they are tested and maintained in
compliance with National Fire Protection Association (NFPA)
72-National Fire Alarm Code.
Before testing the detector, check to ensure that the LEDs are blinking.
If they are not, the detector has lost power (check the wiring) of it is
defective (return it for repair).
