The System Sensor MHR Mini Horn represents a compact, high-performance audible notification device engineered for comprehensive fire alarm notification in commercial and institutional environments. Specifically designed for seamless integration with addressable fire alarm control panels, this red-colored horn delivers reliable sound signaling across challenging architectural spaces where traditional notification appliances may prove inadequate.
Optimized for installations in corporate offices, educational facilities, healthcare complexes, and industrial settings, the MHR Mini Horn provides critical acoustic alerting during emergency evacuation scenarios. Its compact form factor enables discrete mounting in areas with limited spatial constraints while maintaining robust sound output consistent with NFPA 72 notification requirements.
Engineered with precision electronic sound generation technology, the System Sensor MHR ensures clear, penetrating audio signals that can effectively overcome ambient noise environments and facilitate rapid, coordinated building evacuations.
