GST I-9403 Intelligent Sounder Strobe

The GST intelligent sounder strobe is an addressable dual-action notification appliance engineered to deliver synchronized acoustic alerts and high-intensity visual notifications across commercial life safety installations. Manufactured by GST for seamless integration into intelligent addressable fire alarm loops, it receives both operating power and digital control communication directly over the two-wire line without requiring auxiliary power supplies or extra field cabling. The device combines a high-output acoustic horn with a bright flashing visual strobe to penetrate elevated background noise and fulfill multi-sensory emergency notification requirements. Built with electronic soft-addressing capability for rapid system commissioning, low current draw to maximize total loop device density, selectable acoustic tones, and a durable flame-retardant housing for surface mounting, it offers an efficient and dependable life safety evacuation solution for commercial offices, schools, hotels, healthcare facilities, and industrial venues.
