DEMCO Electronic Sounder D-145 and Sounder/Beacon D-155’s compact design is acoustically very efficient, capable of generating high sound output at low current levels. Both models have a wide angle uniform sound distribution providing good audibility in all directions, thus making them ideal for fire, security and hazard warning. These conventional wall mount devices are available in 4 alarm tones (DC) with locally controllable output levels capable of adjusting the sound intensity to suit intended application. Both D-145 and D-155 operate over a wide input voltage range, and if required, a second stage alarm can be switched to override the selected tone by using a third wire. These versatile features allow both models to work seamlessly with most detection systems incorporating central control equipment.
