Emergency Voice / Alarm Communications System

VARIODYN D1 Digital Output Module

The DOM is the central control element of the VARIODYN® D1. The DOM4-8 and DOM4-24 modules are equipped with four independent audio outputs in order to access four channels.

The DOM is the central control element of the VARIODYN® D1. It has interfaces to all input/output modules, manages and monitors the loudspeaker circuit. Any complex system configuration can be implemented through the networking of multiple DOMs via the Ethernet. The DOM4-8 and DOM4-24 modules are equipped with four independent audio outputs in order to access four channels. Each audio output controls connected loudspeaker zones: the DOM4-8 operates two zones (total of 8 circuits) while the DOM4-24 operates six zones (a total of 24 zones). All power amplifiers are permanently monitored. In the case of an error, a backup amplifier dynamically replaces the defective power amplifier. The changeover occurs automatically from the DOM.

Features & Benefits:
  • All the functions of an alarm and evacuation system in a 19"-module (DOM)
  • Cross-linkable via Ethernet
  • Ongoing monitoring of all function-relevant system components
  • Automatic and dynamic switching to redundant backup amplifier
  • Ongoing automatic volume control (AVC)
