Signal Communications DVS-150-4 - 150 WATT 4 ZONES MIC DM PS

Effective life safety for many buildings requires improved methods of emergency notification and occupant response. Recognizing this, national, state and local authorities are implementing new requirements for Emergency Voice Alarm systems. Combining audible tones, pre-recorded instructional messages and live voice has proven to enhance occupant awareness, understanding and reaction during an emergency. SigCom’s DVS+ EVAC panels are fully equipped, pre-engineered solutions, designed to meet these requirements.

DVS+ panels include all of the functionality and features required to provide a complete notification and emergency response system. Designed to provide life safety during a fire emergency, DVS+ performs equally well for notification and control of other emergency and non-emergency conditions. Using a modular design DVS+ panels can be configured to meet the specific needs of an installation. Modularity allows modification and expansion to suit changing needs within a building or system.
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.
