MHR1 New Horn
  • General
  • Feature
  • Specification
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 3.2.4.18.9. The mini-horns can be mounted to single gang back boxes for aesthetically sensitive applications. Synchronization is provided on certain models when using the MDLA module. Minihorns 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 to 49C (32 to 120F) from a regulated DC or full-wave rectified, unfiltered power supply. They are listed to Underwriter’s Laboratories of Canada CAN/ULC S525.
