DSC SDM-100 Two Tone Siren Driver The DSC SDM-100 is a two tone siren driver which means it can be wired to produce a steady alarm tone or a warble tone. This siren driver can handle up to 4 wired sirens and has a 4 ohm load capability. It can be used on systems with power ranges of 6 to 15 VDC and is considered a low current draw peripheral which means it draws minimal amperage. This siren driver uses the pulse of an alarm system's bell outputs to differentiate between the steady and warble tone.  Specifications: Voltage - 6 to 15 VDCCurrent: With 8 ohm load - .45 to 1.0 AmpWith 4 ohm load - .75 to 2.0 Amp dB Output: With 8 ohm load - 110 to 116 dBWith 4 ohm load - 112 to 119 dB Mounting - Double-sided tape (included) Dimensions - 2.25" x 2.75" Powers up to 4 speakers 4 Ohm load capability Low current draw High sound output Yelp/pulsing tone output Wide operating voltage range Compact solid-state construction
