Notifier Mini-Horns MHW User Manual

SpectrAlert® Advance
Mini-Horns

MHR/MHW

General

The SpectrAlert® Advance series of mini-horn sounders are
designed to simplify installation to provide primary and sec­ondary signaling for fire and security applications.

The MHR and MHW 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. The mini-horns
offer high and low volume settings, and temporal or non-tem­poral tones. The horns can be mounted to single gang back
boxes for aesthetically sensitive applications. Synchronization
is also provided when using the MDL3R, MDL3W module or
any Notifier panel with the System Sensor sync protocol.

The MHR and MHW mini-horns can operate between 32 and
120 degrees Fahrenheit from a regulated DC or full-wave recti­fied, unfiltered power supply. They are listed to Underwriter’s
Laboratories.
