Description

The Fire-Lite D350PL(A) and Fire-Lite D350RPL(A) Intelligent Photoelectric Smoke Duct Detectors provide low-flow technology that enables duct smoke detection throughout a broad range of airflow environments in HVAC applications. The low-flow technology can detect smoke at airspeed velocities of 100 feet per minute (0.5 m/sec) or greater while continuing the same reliable performance to 4,000 feet per minute (20.32 m/sec). Also, the intelligent low-flow duct detectors sample air currents passing through a duct and give a dependable performance for the shutdown of fans, blowers, and air conditioning systems, preventing the spread of toxic smoke and fire gases through the protected area.

In general, D350PL(A) and Fire-Lite D350RPL(A) are compatible with all Fire-Lite addressable panels. D350PL(A) and D350RPL(A) provide a remote alarm output for use with auxiliary devices, such as the RA400Z(A) remote LED annunciator, as well as remote test capability with the RTS451(A) or RTS451KEY(A) Remote Test Stations. Besides, the D350PL(A) and D350RPL(A) detectors are designed for ease of wiring; their housing provides a terminal strip with clamping plates.
