Description

Product Data Sheet

Fire Detection, Control Panels and System Accessories

Model 2151BAUS photoelectric smoke detector can be used with a variety of adapter bases in several wiring configurations and voltages. Other features include: low current draw, stable performance in high air velocities, built-in tamper resistant base design, dual LEDs, removable cover, easy-clean chamber and built-in magnetic test switch. The 2151BAUS is designed to meet the performance criteria designated by AS1603.2-1997. The sensing chamber is sealed against back pressure air flow. The chamber top is covered by a one piece molded screen which minimizes the entry of dirt and insects. This screen can be removed for cleaning. Additional key features include a variety of mounting bases and a full line of accessories. All 2151BUAS photoelectric smoke detectors contain a unique optical sensing chamber designed to sense smoke particles produced by a wide range of combustion sources. A custom integrated circuit incorporates signal processing to reduce false alarms.
