Bosch Option Bus

The AMAX panel provides BOSCH option bus 1 and option bus 2 (only for AMAX 3000 BE and
AMAX 4000) to connect modules and devices. Each module can be connected to each bus.
A maximum of 14 modules (8 keypads) can be connected to each bus.
The total length of the cable for the connection of all keypads and expansion modules wired to
one option bus must not exceed 700m. Particular modules require limitation in cable distance,
e.g. the last keypad must be placed within 200m.
The AMAX panel tests the communication with the modules and transmits the communication
failure report in case of failure of communication.

Notice!
AMAX 2100 / 3000 provides 12 VDC power supply with a maximum of 500mA for option bus
1. AMAX 3000 BE / 4000 provides a maximum of 900mA for each option bus 1 and 2. When
the total current of the bus exceeds the limit, an external power supply is required.
Notice!
When a data bus address is changed, the module needs to be re-powered to enable the new
address.
