3.4.5 A-Door: Status Switch, Request to Exit, Auxiliary Request to Exit,

Global Unlock Inputs (TB4)
Make the wiring connections for the A-Door Status Switch and Request to Exit inputs (TB4). Use
Figure 10 on page 10 to locate the correct connectors for each controller.
On the master controller, the final input on TB4 can serve one of two purposes. It can either act as
an Auxiliary Request to Exit for the A-Door or as a Global Unlock for the access control system.
For the master controller, determine if your site requires a Global Unlock input or if you need the
Auxiliary Request to Exit input, and make the appropriate wiring connection.
For all other controllers, the final input can only be used as an Auxiliary Request to Exit for the A-
Door. Make the Auxiliary Request to Exit connection if required.
