24VAC/DC detector base for use with 2151 Special Applications Duct Smoke Detector.
The 2151 can be used as a pendant mount detector in no-flow/low-flow air-handling systems (0-3,000 FPM). The pendant /plenum mounted 2151 is to be installed into a B114LP or B114LPBT base. This is the perfect combination for installation in ducts where the air velocity is below 500fpm or for duct sizes as small as 8” in diameter.
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 2151 heads can be combined with the System Sensor B114LP 120VAC base or the B114LPBT 24VAC/DC base.
