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.

6.1 Maintaining the detector
Fig.31
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 environments must be tested and cleaned
more often. Detectors must also be tested and cleaned immediately after a fire.
Failure to maintain detectors may result in needless false alarms.
Reattach cover (1) with two screws (2).
