System Sensor 2D51
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.APPLICATIONS
The System Sensor 2D51 low-profile photoelectric smoke detector with a B210LP base tied to the D4P120 is listed to Underwriters Laboratories 268A specifically for use in no-flow/low-flow air-handling systems.FEATURES
