As there are no common/ground connections available on the input terminal block, the diagrams shown above all
utilize the V- connection of the lock outputs terminal block to serve as the ground connection.
Trouble Inputs
Each reader expander can monitor up to 16 trouble inputs used to report trouble conditions such as module
communications problems.
Trouble inputs are used to monitor the module status and in most cases are not physically connected to an
external input.
The following table details the trouble inputs that are configured in the system and the trouble type and group
