Bogen FMH15T Flange Mounted Horn Loudspeaker Fire Alarm

The Bogen FMH15T Flange-Mounted Horn Loudspeaker is a weatherproof, all‑metal 15‑watt horn designed for reliable paging and alert signaling in indoor and outdoor industrial environments. It mounts by flange and includes a built‑in, weather‑sealed tap selector for 70V or 25V constant‑voltage operation, with eight impedance taps to tune output from 0.9 W to 15 W on 70V (and 0.125 W to 15 W on 25V). The unit features a self‑aligning, field‑replaceable diaphragm for easy maintenance, and a heavy‑duty grille plus adapter ring are available (SGHD8 and FMHAR8), along with flush (BBFM6) or surface (BBSM6) enclosures to tailor installation. All‑metal construction with a black enamel finish and screw‑terminal connections make it suitable for hostile environments in places like industrial plants, warehouses, schools, construction sites, transportation terminals, and recreation areas where clear, intelligible voice reproduction and alert signaling are important.
