Photoelectronic Low-Profile Plug-In Detector for Special Applications. For replacement purposes with 4-wire InnovairFlex duct smoke detectors
Note: The 2D51 needs to be used with the D4P120 and B210LP for pendant mount applications.
The 2D51 can be used as a pendant mount detector in no-flow/low-flow air-handling systems (0-4,000 FPM). The pendant /plenum mounted 2D51 is to be installed into a B210LP base and wired to a D4P120 power board-only control unit. The D4P120 power board is capable of controlling up to two 2D51 sensors.Pendant mounted in a standard electrical box within the duct, the twist-in/twist-out head allows easy removal from the base for quick cleaning and maintenance. The 2D51 heads can be locally tested using a magnet or by using the test/reset push button on the D4P120 power board.
