This PIR motion detector is built into a rugged metal enclosure (great for resisting vandalism or accidental damage) and comes complete with an optional surface mount angled housing. This sensor operates on 12 or 24 Volts AC /DC and is field selectable. The unit has a long range 50’ wide angle detection area. There is an on board 5A @ 250V “C” Form (N.O. / N.C.) relay with a built in adjustable timer to control the relay from 3 to 30 seconds. A great additional sensor for the ABS-1000 , as well as for use with other alarm systems, or for use as an annunciator or egress sensor.
