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