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.
SD-2 DETECTOR MAINTENANCE
The SD-2 Detector has been designed to be as
maintenance-free as possible. Normal air-borne
dust, however, can accumulate in the detector
sensing chamber and cause it to become more
sensitive. All detectors must be tested and cleaned
at least once a year. Detectors in dusty environ-
ments must be tested and cleaned more often.
Detectors must also be tested and cleaned imme-
diately after a fire. Failure to maintain detectors
may result in needless false alarms.

An auxiliary door stop (by others) must be
