The System Sensor MHR mini-horns operate at 12 and 24 volts and are ideal for hotel, motel, or residential fire system applications, where a smaller notification device is desired. Also, the mini-horns offer high and low volume settings and temporal or non-temporal tones. Besides, the horns can be mounted to single-gang back boxes for aesthetically sensitive applications. Synchronization is also provided when using the MDL module.

Mini-horns shall be a System Sensor Model MHR or MHW capable of operating at nominal 12 or 24VDC and shall mount to a deep single-gang back box. Furthermore, mini-horn shall be listed to Underwriter’s Laboratories Standard UL464 for fire protective signaling systems. Mini-horns shall operate between 32 and 120 degrees Fahrenheit from a regulated DC or full-wave rectified unfiltered power supply. When used with the Sync•Circuit™ Module, 12-volt-rated notification appliance circuit outputs shall operate between nine and 17.5 volts; 24-volt-rated notification appliance circuit outputs shall operate between 17 and 33 volts.

In addition, the System Sensor MHR mini-horns can operate between 32 and 120 degrees Fahrenheit from a regulated DC power supply or a full-wave rectified, unfiltered power supply. They come listed to Underwriter’s Laboratories Standard UL 464 for fire protective signaling systems.
