GST I-9404 Intelligent Sounder

The GST intelligent sounder is an addressable acoustic notification appliance engineered to deliver high-output emergency warnings across commercial and industrial 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 produces high-decibel audible alarm signals featuring multiple panel-configurable warning tones to penetrate elevated background noise and ensure rapid occupant evacuation. Built with electronic soft-addressing for fast commissioning, low quiescent current consumption to maximize device capacity per loop, and a durable flame-retardant housing designed for surface mounting, it provides an efficient and dependable life safety alerting solution for commercial offices, schools, healthcare facilities, and industrial venues.
