The SDM-100 Siren Driver is a compact, general purpose module for use where high dB sound output is required. The unique circuit design provides a high sound level output with a lower current requirement than comparable units. Careful design of the output stage results in a very low poer loss which maximizes power to the speaker load and maintains a very low heat rise on the output stage for longer life of the solid-state components.
The SDM-100 has a single input which controls the output tone. (Yelp or Pulsing) If the output from the control panel is a steady DC voltage, the SDM-100 will generate a Yelp tone. If the output of the control panel is a pulsing DC voltage, the SDM-100 will generate a pulsing tone which will pulse at the same rate as the input from the control panel.
