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

This First Alert Hardwired Smoke Alarm includes a 10-year battery backup that continues to protect you in the event of a power failure. It uses an ionization smoke detector, and features a loud 85-decibel alarm. One button silences any nuisance alarms, and also tests detector functions. The latching alarm indicator automatically identifies which unit initiated the alarm, even after conditions that set off the alarm have subsided.

System Sensor 2W-B Two 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.
