Codesec ST805 Addressable Sounder Detector Base

The Codesec ST805 Addressable Sounder Detector Base is an addressable sounder detector base engineered to combine high-decibel acoustic alarm signaling with a mounting platform for compatible fire detectors. Designed by Codesec for direct integration into addressable fire alarm control loops, it functions both as a ceiling acoustic sounder and a mounting base for compatible smoke or heat detectors, eliminating the need for separate sounder installations. The unit operates directly on loop power to draw operating power and digital communication without auxiliary power supplies, delivering high-decibel acoustic output to ensure immediate localized occupant warning. Built with a durable flame-retardant white plastic housing, it features digital soft-addressing capabilities for efficient commissioning, low quiescent current draw to preserve loop power, and secure terminal connections suitable for commercial offices, hotel rooms, educational facilities, and institutional buildings.
