Testing and Maintenance
Procedures
All detectors must be tested after installation and following periodic
maintenance. Testing methods must satisfy the authority having
jurisdiction. Detectors offer maximum performance when they are tested
and maintained in compliance with NFPA-72-National Fire Alarm Code.
Before testing, notify the proper authorities that the system is undergoing
maintenance and will be temporarily out of service. Disable the system 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.
Upon completion of maintenance and any subsequent testing, enable any
system functions previously disabled for maintenance and notify the
authorities that the system has been returned to normal service.
Before you check each detector:
●
Check and make sure the LEDs blink.
If they do not blink, and LEDs on other detectors and/or modules on the
same SLC blink:
●
Check the connection between the SLC and the detector.
●
Check the data base to make sure the detector is programmed
correctly.
●
If the LEDs on the detector still do not blink, return the detector to
Johnson Controls for servicing.
●
If the LEDs on the other detectors and/or modules do not blink, check
the SLC connections at the control panel.
The sensitivity and function of each detector must be tested after the initial
installation and periodically thereafter. Refer to the NFPA-72-National
Fire Alarm Code for the required frequency. Check with your local
authority for the requirements in your area.
