B901 door controller

The B901 Access Control Interface Module is a fully supervised, addressable SDI/SDI2 bus
device that allows access control integration for Bosch compatible control panels. This
module offers 14 programmable levels of access authority. Authority for access is controlled
by the user level, the group of the user, the time of day, the door state, and the area armed
state. Control each authority restriction through automatic and manual functions.
The module connects to a B6512 SDI2 bus or using the interconnect wiring connector. You
can connect more than one module to the control panel by wiring them in parallel. This
section includes basic installation instructions.
For detailed instructions, refer to the corresponding document listed in Related
documentation, page 12.
15.1.1

Address settings

Notice!
The module reads the address switch setting only during module power up. If you change the
setting after you apply power to the module, you must cycle the power to the module in order
for the new setting to take effect.
If multiple access control modules reside on the same system, each access control module
must have a unique address.
For valid addresses, refer to B901 address settings, page 131.
15.1.2

Supervision

With any failure to receive an expected response from the module, all keypads show a system
fault. The control panel sends a module trouble report to the central station (if configured for
module trouble reports).
