16 I n p u t D e v i c e s Four -wir e Photoelectric Duct Smoke Detector S u p e r D u c t S e r i e s E S D - 4 W J Overview The SuperDuct four -wir e smoke detector is ideally suited to HV AC applications wher e early indication of combustion is r equir ed within the confned space of ventilation ductwork. SuperDuct detec - tors and contr ollers featur e a unique modular design that speeds installation and simplifes maintenance. Separate housings enable access to either the contr oller or detector without af fecting the other . The detector assembly pr ovides easy access to the smoke sensor , its wiring connections, sample and exhaust tube fttings, and the smoke chamber itself. Air enters the assembly by means of an air sampling tube (or der ed separately), and exits by means of a six-inch exhaust tube (included). The contr oller can accommodate up to two detectors. One or both detectors may be installed r emotely fr om the contr oller . A Category 5 wiring har ness is used for inter connection when detectors ar e installed r emotely fr om the contr oller . Sensitivity testing and diagnostics r eveal some of the most exciting innovations built into SuperDuct. W ith the ingenious SuperDuct r emote test station, a sensitivity test can be performed at any time fr om the safety and comfort of a maintenance of fce or utility r oom. Remote T est/Reset Station The Remote T est/Reset Station pr ovides alarm test or dirty test capability fr om a r emote location. It includes a one-gang plate, momentary SPST switch, r ed alarm LED, yellow tr ouble LED, gr een power LED, and terminal block. Magnetically operated or key-operated models ar e available. T est Magnet Used to activate test r outine fr om either a SD-TRM4 Remote T est/Reset Station, or the detector .
