The DVS+ can provide between 50 and 200 Watts of audio power, field selectable for 25/70.7Vrms operation. Automatic amplifier backup can protect any installed amplifier. Audio output power can be distributed over as many as 20 supervised speaker circuits, field programmed for Class A (Style Z) or Class B (Style Y) wiring. Each amplifier incorporates SigCom’s Intelligent Overload Protection to avoid panel damage without disconnecting the load and disabling the system.

A supervised reverse polarity circuit (NAC), dry contact input or a serial interface can provide the means for DVS+ activation and control. Alarm signals can be automatically or manually directed to selected speaker circuits or to all circuits simultaneously. Eight selectable tones and 2 standard voice messages can be field configured for type, sequence and duration. A total of 14 messages of 30 second duration can be pre-recorded when the DVS-DM8 board is used. Facilities are provided for dual simultaneous messaging. An integral, supervised (Push-To-Talk) microphone is supplied, with the capability for an optional supervised remote microphone. The DVS+ will accept an auxiliary audio input from a telephone page system or similar source.

Every DVS+ panel is pre-engineered, pre-assembled and fully tested.
