Smoke Alarm, 12/24 VDC, 2-Wire, Therm Sen

System Sensor I3 series smoke detector has built-in remote maintenance signaling and in-line terminals with SEMS screws that mount to octagonal and 1-Gang back boxes, 4-square back boxes or direct to the ceiling. It has built-in drift compensation that allows the detector to automatically adjust its sensitivity over time as it becomes dirty. Detector gives trouble indication light if not calibrated properly or if it is dirty. The smoke detector is suitable for both retrofit applications.
