The System Sensor 4WT-B is a white 4-wire, photoelectric i3 smoke detector with a 135°F fixed thermal sensor.
The i3 line redefines installation ease with its plug-in design. This allows an installer to pre-wire bases (included with heads). Also, the large wire entry port and in-line terminals provide ample room for neatly routing the wiring inside the base. The base accommodates a variety of back box mounting methods as well as direct mounting with drywall anchors. Furthermore, to complete the installation, i3 heads plug into the base with a simple Stop-Drop ’N Lock™ action.
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. Furthermore, this feature verifies the initiating loop wiring by providing LED status indication at each detector.
