Rack-mounting and floor-type cabinets for fire alarm systems

Installation information
Ambient conditions
The ambient conditions for the assembly location and surfaces must comply with Class 3k5 according to
DIN EN 60721-3-3. If these climatic conditions cannot be fulfilled, appropriate countermeasures must be taken.
Assembly location and assembly surface
The installation in floor-type cabinets with Fire Alarm Control Panels or Extinguishing Control Computer may be
installed only in dry, clean, conditionally accessible and adequately lit rooms. If several Panels are to be
assembled in one enclosed floor-type cabinet, the maximum bearing strength (Kg/m²) of the floor may have to
be considered (e.g. pile floors).
To prevent the floor-type cabinet becoming top heavy when the pivot frame is open, fix it to a suitable wall.
The fire alarm system or extinguishing system must not be installed in facilities with damaging influences. Parts
of the fire alarm system may be fed through these facilities if the requirements of the DIN VDE 0800 series are
fulfilled.
Assembly material
The panel must be installed with suitable fixing material (screws, threaded bolts) with no mechanical stress on
the assembly surface of the floor-type cabinet. The panel may be operated only when it has been properly
installed on the surface with sufficient bearing power.
Installation height of the operating modules and optical displays
Operating modules and optical displays should be installed between 800 mm and 1800 mm above the place
where the operator stands.
Energy supply
The system is not suitable for connection to an IT voltage supply system.
Disturbance variables
Avoid electrical and mechanical disturbance variables. This applies especially to the installation of panels,
components and installation cables in the direct vicinity of fluorescent lamps or energy cables and mounting on
vibrating, unstable surfaces such as thin partition walls.
Cabinet ventilation
If you believe that the ambient temperature is unsuitable for the installed devices, you must take appropriate
measures to air-condition the floor-type cabinet.
In principle you must prevent heat accumulation between the installed devices and between the devices and the
walls of the floor-type cabinet. Especially ensure that there is an adequate heat buffer between the highest
installed panel and the top of the floor-type cabinet.
Door contact
The floor-type cabinet is fitted with an electrical door contact that monitors when the door is opened. This door
contact may be used in Fire Alarm Control Panels to switch off the master box (MB) of one or more panels.
