2.12 Special function III Operation of the control system at control panel 925 (bus
technology)
If the emergency exit control unit 720-30 or 720-32 is connected to a central control and monitoring panel (bus
control panel ) 925, the switching and display functions at the door / at the terminal are largely the same.
Setting the bus address ( S 6 )
When operated at the bus control panel 925, each control unit must be assigned its own address which must be set
both at the DIP switch S6 of the control unit itself and also at the relevant door unit of the central panel.
Connecting the door control bus
The two-core bus line of the door control bus is connected to terminals A and B of the emergency exit control device.
Note! Do not confuse cables A and B!
For all other information relating to the installation, functional characteristics and commissioning please
refer to the "Operating and installation instructions for the bus control panel model 925".
