Key Extensions
Up to three key extensions can be connected to system tele-
phones: either three key extensions of the model Forum 500 Key-
pad Paper FP 525 / 535 or three key extensions of the model
Forum 500 Keypad Display FP 535. A combination of these key
extensions is, however, not possible.
The following equipment combinations are possible:
The number of key extensions connected to a system telephone
(up to three) can be set in the
Configurator of the Forum 525/
526’s Web Console (in the menu Telephony : Ports : Upn or
Telephony : Devices : VoIP Phones ). Here the keys can also be
programmed as call keys or assigned functions or destination call
numbers. Users can change this programming as required.
The maximum distance between the connecting socket that the
telephone/key extension device combination is operating through
and the Forum 525/526 must be less than 1000 metres. You will
need a plug-in power supply unit no. 90035810 to provide power.
