    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 are ideal for residential, hotel or motel fire system applications, where a smaller notification device is desired. The mini-horns come in versions that offer high and low volume settings, temporal or non-temporal tones, synchronization and silencing to meet the intent of the National Building Code Section The mini-horns can be mounted to single-gang backboxes for aesthetically sensitive applications. Synchronization is provided on certain models when using the MDLA module. Mini-horns with silencing have an accelerated silence test feature which allows testing of the silence operation without waiting for the entire time-out period. The MHR and MHW mini-horns can operate between 0°C to 49°C (32°F to 120°F) from a regulated DC or full-wave rectified, unfiltered power supply.
