The newest DOM4-8 hardware is not compatible with the DOM firmware 2.6 up to 2.10. For projects requiring
extension or to replace a DOM4-8 featuring DOM firmware 2.6 up to 2.10, it is necessary to order instead
583361.22.UL. This DOM4-8 is fully compatible with firmware version 2.6 up to 2.10 and complies with the

The DOM (Digital Output Module) 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 and electro-acoustic emergency
warning system per EN 60849 and EN 50849. Large or complex system
configurations can be implemented through the networking of multiple DOMs via
Ethernet. The DOM offers a high level of automatic and constant monitoring as
standard. All connected power amplifiers are permanently monitored by the DOM
and if.a power amplifier becomes faulty, it can be replaced dynamically by a
backup amplifier or a backup amplifier channel. The switchover is done
automatically by the DOM. The loudspeaker lines are permanently monitored for
short circuit, ground fault, and failure as well as impedance deviation. Faulty
loudspeaker zones are separated in a non-reacting manner. 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 each amplifier channel can be controlled. Additional
filters like parametric equalizer, high-and low pass filter are available. All errors
are recognized, displayed and recorded within few seconds meeting the
standards. For special applications such as e.g. tunnel, a delay in all four
channels can be programmed up to 9.9 sec.
With the new Firmware it is now possible to connect up to 400 units and get
advantage of the new logical functions which makes it much easier and efficient
to configure the DOM.
