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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLow frequency audible output targets sleeping occupants and hearing-impaired individuals more effectively than standard high-frequency tones\u003c\/li\u003e\n  \u003cli\u003eCeiling-mount form factor for straightforward installation on standard electrical boxes\u003c\/li\u003e\n  \u003cli\u003eRed housing provides immediate visual identification as a fire alarm notification appliance\u003c\/li\u003e\n  \u003cli\u003eDesigned for use on supervised notification appliance circuits in fire alarm systems\u003c\/li\u003e\n  \u003cli\u003eSold as a single unit (EA), one device per package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style notification appliance for use on supervised fire alarm notification appliance circuits in residential and light commercial fire alarm systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed fire alarm technician in accordance with NFPA 72 and all applicable local codes.
