contact will open and interrupt current
IMPORTANT: THE UNIT MUST BE TESTED AFTER THE
INSTALLATION, BY THE END USER, TO ASSURE
THAT THE DOOR CLOSER UNITS FUNCTION PROPERLY
WHEN THE ALARM SYSTEM IS ACTIVATED. THE ENTIRE
SYSTEM MUST ALSO BE TESTED PERIODICALLY AFTER
THE INITIAL INSTALLATION TEST, IN CONJUNCTION WITH
THE TESTING OF THE FIRE ALARM SYSTEM. THE END
USER IS ALSO RESPONSIBLE FOR THE ADJUSTMENTS
AND MAINTENANCE TO RETAIN THE SYSTEM IN
WORKING ORDER.
1. After installation is completed, recheck all
connections. Apply power to units.
2. Open door so slide block engages with hold
open assembly.
3. Advise fire officials prior to testing.
5. If the closer is used in conjunction with a
detectored unit, trip the test switch of the
main closer detector as explained in the test
procedure for that unit. After a short time
delay, the hold open electromagnet of both units
will release and the doors will close.
Resetting the test switch will allow
the units to return to standby.
4. Activate system into alarm so the electromagnet
releases and the doors closes.
