About the 4-Wire

Flexible 4-wire photoelectric duct smoke detector designed to fit square and rectangular duct configurations. Integrated low-flow technology supports air velocities from 100 to 4,000 ft/min.

The plug-in sensor provides current sensor technology and resistance to false alarms. Features include rotary address switches, a front- or rear-installable sampling tube requiring no tools, a 3/4-inch conduit knockout, and an easy-access Test/Reset button with LED status indication. A patented interconnect feature supports multi-fan shutdown.

Rated for operating temperatures from –4°F to 158°F and humidity from 0% to 95% non-condensing.
