GST DC-M9402 Conventional Sounder Base

The GST conventional sounder base is an acoustic notification appliance designed to provide localized evacuation alerts directly at the detector location across commercial life safety installations. Manufactured by GST for universal compatibility with standard 24V DC conventional fire alarm panels, it combines a high-output audible alarm with a functional detector mounting socket, eliminating the need for standalone sounders and separate ceiling boxes. The unit operates efficiently on standard fire alarm notification circuits, simplifying field installation through basic two-wire loop connection. Built with low power consumption to preserve circuit loading, selectable acoustic tones, and a durable flame-retardant housing designed for direct surface mounting, it provides a practical, space-saving evacuation alert solution for commercial offices, hotel rooms, dormitories, and educational institutions.
