22.3.4 Connecting control inputs
The call station interface has two control inputs (refer to
figure 22.6 and table 22.3). The control inputs can
receive signals from third party equipment that must
trigger actions in the Praesideo system. The control
inputs can be configured via the configuration webpage
of the remote call station (see section 43.4.4). The
maximum length of the connected cables is 3 meter.
It is also possible to supervise the cables fo short-circuits
and open connections (see figure 22.7 and figure 22.8).
Whether a control input is actually supervised or not is
defined in the configuration.
22.3.5 Connecting a ground
To reduce interference from electromagnetic fields and
electrostatic discharges, we recommend to connect the
housing to ground. Use the ground connector of the call
station interface. Refer to figure 22.5.
22.4 Installation
The call station interface can be attached to a wall or
any other flat surface using a bracket (see figure 22.9).
The distance (d) between the holes in the bracket is 40
mm.
Mounting of this bracket and the unit on a drywall sheet
construction requires screws with a minimum screw
