    InnovairFlex™ 2D51 Duct Smoke Detector

    2D51 duct smoke detectors are low-profile photoelectric detectors designed for special applications, specifically for use in no-flow or low-flow air-handling systems (0 to 4,000 FPM).

    Overview

    2D51 duct smoke detectors are low-profile photoelectric detectors designed for special applications, specifically for use in no-flow or low-flow air-handling systems (0 to 4,000 fpm). Pendant or plenum mounted 2D51 detectors are intended to be installed into B210LP bases and wired to a D4P120 power board only control units. D4P120 power boards are capable of controlling up to two 2D51 sensors. Pendant mounted in a standard electrical boxes within ducts, the twist-in/twist-out heads allows easy removal from bases for quick cleaning and maintenance. 2D51 heads can be locally tested using a magnet or by using the test/reset pushbutton on the D4P120 power board.
