Conventional Products—2400AT and 2400AIT Direct 2-Wire Smoke Detector 11
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.
Before testing the detector, check for the presence of the flashing LED.
If it does not flash, power has been lost (check the wiring) or it is defective
(return for repair).
Detectors must be tested after installation and periodic maintenance.
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, notify the proper authorities the system is
back in service.
