Potter LFH-24W LFH Series Low Frequency Audible Sounder, White

Designed for life-safety and security applications, the Potter LFH-24W LFH Series low frequency audible sounder delivers NFPA-compliant 520Hz signaling specifically for sleeping areas. The Potter Electric Signal LFH-24W combines a low-profile, tamperproof form factor with contractor-friendly features — a universal 4" Super-Slide mounting bracket for fast pre-wiring and the Checkmate instant voltage verification to confirm voltage drop and current draw on site. The horn produces a 520Hz square-wave temporal 3 tone with a jumper-selectable normal or loud output and supports temporal 4 synchronization when used with the Potter GTSM module. With 33V DC input and an 84 dB emission, the LFH-24W is engineered for reliable audible performance in security, surveillance, and monitoring installations. Choose the LFH-24W to simplify installation, maintain code compliance, and reduce service calls.
