System Sensor HCRL2-LF Low Frequency Sounder Ceiling Red

Product Description

The SYSTEM SENSOR HCRL2-LF is a low frequency ceiling-mount sounder designed for life safety notification systems. Low frequency audible devices operate at a fundamental tone of 520 Hz, which is proven to improve response times for sleeping occupants and individuals who may not reliably respond to higher frequency signals. The HCRL2-LF ships in a red housing for quick visual identification during inspections and complies with the application requirements driving adoption of low frequency sounders in residential and light commercial fire alarm systems. Installation is performed by licensed fire alarm technicians as part of a supervised notification appliance circuit.

This sounder is suited for ceiling-mount installations in residential occupancies, hotels, dormitories, and other sleeping areas where low frequency audible notification is required or specified by the authority having jurisdiction. It connects to a fire alarm control panel notification appliance circuit and is intended for indoor ceiling applications. The red housing meets common color-coding conventions for fire alarm notification appliances.
