DOM is the central control element of VARIODYN D1. It has interfaces to all input/output
assemblies, administers and monitors the loudspeaker circuits. For voice alarm systems as
per DIN VDE 0833-4. Any complex system configuration can be implemented through the
networking of multiple DOMs via the Ethernet. All power amplifiers are permanently monitored.
In case a power amplifier is faulty, it can be replaced dynamically by a spare amplifier.
The switchover is done automatically via the DOM. Loudspeaker cables are continually
monitored for short-circuit, short-to-ground, interruption and impedance vari ation. Faulty
loudspeaker areas are separated without reaction. A DOM contains storage capacity for
preset announcements, which can be used for alarm texts and signals (escape alarm,
caution signal) and warning signals (gongs). The volume of each source and ampli fier
channel can be regulated. Other filters, e.g., parametric equalizers, high and low pass filters
and delays, are also available. All disturbances are recognized within a few seconds in
compliance with standards, displayed and logged. For special applications, e.g., tunnels,
delays of up to 9.9 seconds can be programmed. The control unit DOM4-8 is equipped
with 4 independent amplifier channels in order to operate 8 loudspeaker areas or 4 loudspeaker
circuits in VARIODYN D1 Loop Technology. There is also the option of mixing loop
and spur technology with a DOM.
