System Sensor 2W-B i3 Series 2-wire, Photoelectric i3 Smoke Detector

System Sensor i3TM series smoke detectors represent significant advancement in conventional detection. The i3 family is founded on three principles: installation ease, intelligence, and instant inspection.

•Stop-Drop 'N Lock attachment to base •Removable detector cover and chamber

Plug-in detector line, mounting base included •Large wire entry port

•Wide-angle, dual-color LED indication •Loop testing via EZ Walk feature

In-line terminals with SEMS screws

The i3 series provides wide-angle red and green LED indicators for instant inspection of the detector's condition: normal standby, out-of-sensitivity, alarm, or freeze trouble. When connected to the 2W-MOD2 loop test/maintenance module or a panel with the i3 protocol, the EZ Walk loop test feature is available on 2-wire i3 detectors. This feature verifies the initiating loop wiring by providing LED status indication at each detector.
