The controller can communicate upstream to the host computer using RS-485 multi-dropped
or Ethernet. It has eight analog input devices and eight relay outputs. With its analog input
devices, the controller verifies, for example, if a lock is closed or open. The relay outputs can
be used, for example, to activate lock mechanisms if access is granted, or activate the burglar
alarm system if an intrusion or system alert is detected. If the eight inputs and eight outputs
on the board are not enough to configure the system, up to three additional extension boards
can be connected. The extensions offer 8 or 16 additional inputs and outputs.
In the Bosch Access Host Systems the setup procedure for a controller is made very simple
and fast by the use of door templates. Once selected, all the inputs and outputs are
predefined. These settings can be changed to choose every free contact of the controller or a
connected extension.
