The  Hardwired 4-wire Smoke and Heat Detector is a great dual detector that helps you protect your home from most fire dangers. Additionally, it’s very easy to install, test, and maintain.

But if this isn’t what you’re looking for, please take a look at our other smoke detectors.

Installation ease:

This detector redefines installation ease with its plug-in design. So this allows an installer to pre-wire bases (included with heads). The large wire entry port and in-line terminals also provide ample room for neatly routing the wiring inside the base.

Additionally, the base accommodates a variety of back box mounting methods as well as direct mounting with drywall anchors. To complete the installation, heads plug into the base with a simple Stop-Drop ’N Lock™ action.

Intelligence:

The Hardwired 4-wire Smoke and Heat Detector also offers a number of intelligent features to simplify testing and maintenance. 2-wire detectors can generate a remote LED indicated maintenance signal when connected to the loop test/maintenance module or a panel equipped with the protocol. The SENS-RDR, a wireless device, also displays the sensitivity of  detectors in terms of percent-per-foot obscuring.

Instant inspection:

The detector additionally 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 loop test/maintenance module or a panel with the protocol, the EZ Walk loop test feature is available on 2-wire detectors. This feature verifies the initiating loop wiring by providing LED status indication at each detector.
