User Manual
Commissioning
To operate several devices connected to the same room controller, set an address for
each one. Only one device operates with the factory-set default.
The addresses of the room operator units are set by DIP switch on the back of these
units.
Bus address ADR0 ADR1
0x3C OFF OFF
0x3D ON OFF
0x3E OFF ON
0x3F ON ON
In the standard application with only one reader, address 0x3C is used for the HCH3.2
chipcard holder. This address is preset by the manufacturer (both ADR switches to
OFF).
Note
The volume for the 3-tone chimes can only be set by dismounting the unit, and must be
set by qualified personnel only. The kind of chime (tone 1 / tone 2 / tone 3) is
determined by a parameter in the room controller.
