Siemens ADBH-11 Fire Alarm Audible Detector Base provides a robust foundation for life-safety systems, integrating audible notification capabilities directly into the detector mounting point. This versatile component simplifies installation while ensuring clear, high-decibel signaling for rapid emergency response.

- Operating Voltage: 16 to 33 VDC - Sound Pressure Level: Up to 85 dBA @ 10 feet - Compatible Head Series: Siemens Addressable Detectors - Operating Temperature Range: 32 to 120 degrees Fahrenheit - Mounting Configuration: Standard 4-inch square or octagonal box

Compared to legacy notification appliances that require separate wiring for sounders and sensors, this integrated base streamlines device deployment and reduces total system footprint. The modern design eliminates the need for additional wall-mounted horns in many applications, offering a cleaner aesthetic without compromising NFPA compliance or notification reliability.

Advanced Signaling and System Integration

Engineered for high-performance safety environments, the ADBH-11 utilizes advanced circuitry to synchronize audible alerts across the loop. Its low current draw ensures maximum efficiency, allowing for a higher number of devices per notification circuit while maintaining consistent output levels. By consolidating detection and notification, the Siemens architecture minimizes installation labor and allows for precise, localized alerting during fire emergencies.
