Cable routing
Observe the safety information on page 2.
For cable routing we recommend the use of fire protected cables retaining their function E90 or E30.
However, this has to be agreed with the Engineer or, if necessary, with the local fire protection department.
Do not reduce the cable cross sections specified in the cable lengths table.
All cables of the control centre (except the mains supply cable) carry 24V DC and have to be routed separate
from the mains supply cable.
Adhere to the pertinent VDE regulations when routing the cables.
Do not use the green/yellow conductor.
Ensure that the mains cable can be switched via an external or customer-supplied two-pole switch element or
a switch element controlling all poles.
Control centre installation
Note that the control centre has to be installed in a dry room.
Concealed housing
Refer to the sketch below for the installation position
Open central control and remove the housing
top section (door) from the housing bottom section.
Fasten the housing bottom section in the wall cut-out
(cut-out dimension 335 x 350 x 95) and
refit the housing top section.
Also possibility for surface mounting with the included frames.
Installation of the Break glass unit, ventilation buttons and detectors
Ensure that the Break glass unit and the ventilation buttons are visible and well accessible. Do not fit behind
protruding walls, door panels or hidden by the building structure.
Note: Installation height of the Break glass unit = 1.4 m above floor top edge.
Install the automatic detectors in accordance with the enclosed operating manuals.
Installation
Lead the connection cables into the housing of the control centre from above.
All connection terminals (except the mains terminals) are of the plug-on type.
Connect the connection cables in accordance with the terminal plan. Ensure that the connections are made
correctly.
Incorrect clamping, mixing up numbers or colours could lead to malfunctions of the central control or of the
external components.
Notice:
Smoke central units in metal housing
are only for surface mounting.
