How to address the B901 or D9210C on the SDI bus and how does the panel report an SDI Trouble.

[#1]

• The interface module rotary switches provide a TENS and ONES setting for the module’s address.
• When there is a loss of SDI data to the B901 or D9210C, the relay used to lock or unlock the door will behave according to the setting of the TENS switch.  The ONES switch sets the literal address of the door.
• Set the address by setting the rotary switches based on the table below.
