System Sensor 2W-B 2-Wire Photoelectric i3 Smoke Detector

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

Installation ease. The i3 line redefines installation ease with its plug-in design. This allows an installer to pre-wire bases (included
with heads). 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. To complete the installation, i3 heads plug into the base with a simple Stop-Drop ’N Lock™ action.

Intelligence. i3 detectors offer a number of intelligent features to simplify testing and maintenance. Drift compensation and smoothing algorithms are standard with the i3 line to minimize nuisance alarms. 2-wire i3 detectors can generate a remote LED- indicated maintenance signal when connected to the 2W-MOD2 loop test/maintenance module or a panel equipped with the i3 protocol. The SENS-RDR, a wireles devise, displacys the sensitivity of i3 dectors in terms of percent-per foot obscuration 

Instant inspection. 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
