Description

All models of the U-MH series & U-MHT Series horns and horn/strobes provide a continuous or coded horn signal, depending on the pattern of the voltage applied.

Additionally models U-MHT-1G, U-MHT-1G-W, U-MHT, U-

MHT-W and U-MHT-MCS, U-MHT-MCS-W provide a field selectable temporal tone.

The Adapter feature offers four field selectable candela settings – 15/75, 30/75, 75 or 110

Detail

– Adapter selector switch

Models U-MH-1G, U-MH-1G-W & U-MHT-1G, U-MHT-1G-

W mount on a single gang box while the U-MH, U-MH-

W, U-MHT, U-MHT-W, U-MH-MCS, U-MH-MCS-W &

U-MHT-MCS, U-MHT-MCS-W have a universal mounting plate to mount on a single gang, double gang or 4" square back box.

Siemens Fire Safety notification devices are designed with the installer in mind. They are constructed with all of the electronics inside the housing and not in the box. This design helps eliminate possible ground faults from crowded electrical boxes.

The strobe construction consists of a Xenon flashtube with solid state circuitry for maximum reliability and efficiency. The full range of strobes have a rounded dome shape made of clear Polycarbonate.

Strobe synchronization requires the Dual Sync Control

Module or PAD-3.
