Overview
Designed for reliable life-safety notification in commercial and institutional environments, the Potter Electric LFHS-177R horn strobe combines powerful low-frequency audio with a bright 177Cd visual signal to ensure occupants and first responders notice alarms quickly. This LFHS Series horn/strobe produces a 520 Hz square-wave temporal 3 tone and ships configured for 24VDC operation, making it an ideal choice for fire protection, building security and monitoring applications where low-frequency performance improves response for sleeping or impaired occupants.
Installers benefit from the Super-Slide® metal mounting plate, concealed locking mechanism and the patented Checkmate® instant voltage verification — features that speed wiring, testing and troubleshooting on new builds or retrofit projects. Jumper-selectable loud/normal dBA and multiple fixed candela options let you meet code and site-specific visibility requirements, while temporal 4 synchronization with compatible panels keeps multi-device systems coordinated. ANSI/UL 464 and ANSI/UL 1971 listings and a five-year limited warranty deliver the compliance and reliability operations teams expect.
Specify the Potter LFHS-177R for robust audible/visual notification in fire alarm, security and surveillance systems — order now to simplify installation and enhance building-level monitoring.
