<br />DVS.25 I DVS.50 <br />Voice Evacuation <br />Control Panel <br /> <br />Overview <br /> <br />The DVS Series Voice Evacuation Control Panel (VECP) contains a state of the <br />art 25 or 50 watt high efficiency, digital power amplifier for use in <br />life-safety applications. The DVS-25 and the DVS-50 are packed with options to <br />enhance the voice evacuation package and to significantly increase the ease of <br />installation. <br /> <br />Features such as the supervised internal microphone, low current chaw, undistorted <br />25 or 50 Watt sine power, standard digital message unit and four speaker loop <br />outputs make the DVS-25 or the DVS-50 the ideal choice for critical life safety <br />applications. Sixty seconds of pre-recorded voice messages can be programmed <br />into the digital message unit. These messages can be activated by either 24 VDC <br />polarity reversing or dry-contact inputs. <br /> <br />A built-in auxiliary audio input allows the DVS to interf8ce to telephone paging <br />systems increasing the functionality of the system and adding to the <br />value offered to the end-user. Additional non-fire emergency messages can <br />be added to the system and used to alert building occupants of conditions <br />such as weather alerts, chemical spills and gas leaks. Custom <br />programmed messages and alert tones are also available. <br /> <br />Diagnostic meter bars, which indicate speaker load or signal levels on the audio <br />channels, plug in terminal connections and an installer's system test button make <br />the DVS one of the most installer friendly panels on the market. SigCom's intel- <br />ligent overload protection feature limits the output power to a maximum preset <br />level. This protects the panel without disconnecting the load and disabling the <br />evacuation system. <br /> <br />@ <br />LlSRD <br /> <br />?~...:...., <br />. . <br />i -~; I <br />\'::..~. :~./ <br />(pending) <br /> <br />MEA <br /> <br />(pending) <br /> <br /> <br />Features <br /> <br />· High efficisy Class '0' digital amplifier <br />· 24 VOC polarity reversing or dry <br />conIaCl activation <br />· Low amnt draw <br />.
