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.

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.

Caution

For USA: only use a power supply of the type Mean Well PLN-30-24, PLN-30-36, PLN-30-48, PLN-60-24, PLN-60-36, PLN-60-48, PLN-100-24, PLN-100-36 or PLN-100-48.

Other types of power supply are not tested with Praesideo and may cause harm.

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.
