i³™ Series 4-Wire Smoke Detector

i³™ Series 4-wire smoke detectors represent significant advancement in conventional detection. The i³ family is founded on three principles: installation ease, intelligence, and instant inspection. The i³ line redefines installation ease with its plug-in design. This allows an installer to pre-wired 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 backbox 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.

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. 4-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.

i³ Series detectors provide a wide-angle, red and green LED indicator 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 4-wire i³ detectors. This feature verifies the initiating loop wiring by providing LED status indication at each detector.
