The Siemens U-MMT-S17-W-C series 8-tone horn operates on a current of 20 to 40ma at 24Vdc depending on the tone selected. The audio portion of the signal provides a 91 to 97 dB output. The UMMT mounts on a single gang, while all other units are either 1, 2 gang, or 4 square mountings.
Cerberus Pyrotronics notification devices are designed with the installer in mind. Also, the U-MMT series devices are constructed with all of the electronics in the housing and not in the box. This design helps eliminate possible ground faults from jamming everything in the box. Units are also available in two different colors, red or white.
In general, the Siemens U-MMT-S17-W-C units construction consists of Xenon flashtube with solid state circuitry for maximum reliability and efficiency. Besides, the full range of new strobes have a rounded dome shape made of clear Lexan®. FIRE letters are visible on the front mounting plate. The overall lens is 2.0 x 2 7/8 with a height of 1 3/8.
Maximum dBA output, very low inrush current, as well as the lowest operating current DC or Full Wave, are characteristics of all new Cerberus Pyrotronics devices. The electronic U-MMT horns provide maximum reliability and low current drain for every application.
