Requirements for the installation site and installation surface
The floor type cabinet installation with voice alarm systems may only be installed in dry, clean, and adequately lit
areas with restricted access acc. to DIN EN 60721-3-3. If several voice alarm system components are to be
installed in an enclosed floor type cabinet, it is necessary, for example, to consider the maximum load capacity
(kg/m²) of the floor (e.g. pile floors).
To prevent the floor type cabinet from becoming top heavy when the pivot frame is open, it must be
fastened to a suitable wall !
Devices with visual displays
As a rule, the visibility of the visual displays must be ensured when installing the devices. For devices with visual
displays, an installation height of 1,600 mm (+ 200 mm) above the standing surface of the operator is
recommended.
Weight of the installation devices
In general, heavy devices are installed below and light devices above. Due to the heavy weight of the power
amplifiers, they must be fastened/secured separately with special installation brackets. In principle, an additional
installation bracket must be provided for the combination of a DOM and two power amplifiers.
Max. two double final amplifiers may be installed one above the other. The lower power amplifier is also screwed
on with a installation bracket.
A ventilation panel (Part No. 583708) is installed beneath this, and a DOM is installed above the amplifier
combination. This results in a 6 HU combination, and the power amplifiers can always be connected with the
system cables in this arrangement (see 3.4.1).
Cabinet ventilation
If an ambient temperature exceeding the ratings specified in the technical data of the installed devices is expected
in the upright cabinet, the cabinet must be ventilated. In principle, heat accumulation between the installed devices
and between the devices and the walls of the floor type cabinet must be prevented.
In the event of high thermal influences within an installation cabinet, individual components should be separated
above and below by ventilation grating (Part No. 583708).
Installation kit for fuse switch disconnector
The installation kit (Part No. 583716 – optional) can be integrated into the VARIODYN
®
D1 cabinet system and,
together with the optional fuse switch disconnector and fuse link, makes it possible for the voice alarm system’s
emergency power supply/batteries (24 V DC) to be switched off completely.
3 HUs are required for the installation kit for rack mounting. For additional information, consult document
798673.HO.
