Normally, the call station interface and the remote call
station are powered from the network. To make sure
that they receive power when the network is not
available, external power supplies can be connected to
the call station interface and the remote call station. See
section 22.3.3 for more information.
20.3.5 Connecting control inputs
The remote call station has 2 control inputs (refer to
figure 20.5 and table 20.1). The control inputs can
receive signals from third party equipment that must
trigger actions in the Praesideo system. The control
inputs can be configured to act on contact make or on
contact break (see section 43.4.4). The maximum length
of the connected cables is 3 meter.
It is also possible to supervise the cables for
short-circuits and open connections (see figure 20.6 and
figure 20.7). Whether a control input is actually
supervised or not is defined in the configuration.
Warning
For safety reasons, you must use a current
limited external power supply complying with the
60065 standard for audio/video usage or
equivalent, with a maximum output current of 5A,
or you must use an external fuse (5 A max, slow)
in the wiring of the Kycon KPP-4P connector.
For application in emergency sound systems in
Europe, the installer must use a power supply
with EN54-4 certification.
