Bosch FMM-462-D

The Bosch FMM-462-D is a double-action pull station designed to minimize nuisance alarms in high-traffic areas while maintaining reliable fire alarm activation in emergencies. Unlike single-action stations, this POPIT module requires two deliberate actions—lifting the protective cover and pulling the handle—to trigger the alarm system, significantly reducing accidental activations in public spaces, warehouses, and facilities with pedestrian traffic. The die-cast metal housing with 14-gauge plated steel backing and corrosion-resistant construction ensures durability in demanding environments, while the latching alarm lever provides clear visual feedback of activation status. The key-locked reset mechanism adds tamper-proof security, ensuring the station cannot be reset without proper authorization.
