page 2 a05-193-02 testing and maintenance test detector reinstall or replace screen check sensitivity vacuum and/or blow-out screen and chamber smoke detector maintenance nuisance alarms from smoke detectors can be caused by a number of conditions, but one of the more prevalent is lack of proper maintenance. everyday dust, grime, and moisture can render detectors ineffective or change sensitivity levels. ease of maintenance nfpa 72 requires that all smoke detectors shall be visually inspected in place at least semiannually to identify missing detectors, detectors with impeded smoke entry, abnormally dirty detectors, and detectors no longer suitably located because of occupancy or structural changes. the standard also goes on to say that a test shall be performed annually to assure that each smoke detector is operative and produces the intended response. system sensor detectors have been designed with these requirements in mind. detectors may be disassembled quickly to allow convenient access to the special .020 2 (0.5mm) mesh insect screen and chamber. the screen should be removed and thoroughly cleaned with a soft brush or vacuum to remove all loose and excessive dirt buildup. clean compressed air is recommended to blow out any remaining debris on the screen or in the sensing chamber. simple testing test by pushing recessed switch with any 0.1 2 maximum diameter object photo unit can be tested by inserting calibrated test card and moving it counterclockwise into position. note: detector cover removed once cleaned, the detectors must be reinstalled and tested to insure proper operation of the system. all direct-wire detectors are equipped with a recessed switch that can be activated using any 0.1 2 maximum diameter object. when the switch is activated, the led on the detector should light within 20 seconds to indicate alarm status. plug-in detectors (with separate base) incorporate the use of a magnet test. the 400 series photo can also be tested with a calibrated test card. a special slot in the screen housing allows the test card to be inserted into the chamber. the led should indicate a latched alarm condition after 20 seconds when the alarm end of the card is used; no reaction should occur when tested with the no alarm end. these built-in test functions are designed to simulate a 3% per foot obscuration level on the ionization units and a 4% per foot obscuration on the photoelectronic units. this is more than sufficient to determine if the detector will alarm, but is not an adequate way to test and verify a units sensitivity as required by nfpa 72. instead, use the MOD400R sensitivity test module to satisfy the nfpa requirement for testing sensitivity. system sensor worldwide manufacturing & distribution in canada: telephone: 905-812-0767 fax: 905-812-0771 in china: telephone: 852-2191-9003 fax: 852-2736-6580 in the far east: telephone: 852-2191-9003 fax: 852-2736-6580 in india: telefax: 91-022-8202564 in italy: telephone: 39-40-9490-111 fax: 39-40-382137 in the united kingdom: telephone: 44-1403-276500 fax: 44-1403-276501
