Product Overview
The 4WT-B is a 4-wire, photoelectric i3 smoke detector with a 135°F fixed thermal sensor.
System Sensor i3 ™ series 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-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.
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 wireless device, displays the sensitivity of i3 detectors in terms of percent-per-foot obscuration.
