3.4 SPECIAL OPERATIONAL FEATURES
Some installation-specific features are exercised, as required by
the system. These features are implemented as shown in Figures 4
and 5.
3.4.1 Auxiliary Input & Output
For optimum usability in different applications, the controller’s
auxiliary input and output can be configured in ten different
modes of operation. Refer to Setting the Auxiliary Mode, on
paragraph 4.8.
3.4.2 Request to Exit Button (REX)
The REX pushbutton is located within the premises and is used to
open the door from the inside. It is usually located in a convenient
location (e.g.: next to the door or at a receptionist’s desk). The
door chime in the BL-D40, (if enabled), does not sound when the
REX pushbutton is used to open the door.
The function of the REX pushbutton depends on the Lock Strike
relay, whether it is programmed for failsafe or for fail secure
operation.
