System Sensor 2W-B Two Wire Smoke Detector

System Sensor 2W-B Two Wire Smoke DetectorMost all modern alarm system now support this 2 wire type smoke detector. A two-wire smoke sends the power and zone circuit down the same two wires. We're often asked which type we recommend, 2 wire type or 4 wire type. If you are going to have only a few

System Sensor SYS-2W-B 2 Wire Smoke Detector

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.
