Control for the corresponding doors in
Centaur.

De-energized:
During a communication failure, the
normal state of the lock output is
De-energized. When Lock #1 or Lock
#2 is activated, power is
applied
to the corresponding lock output to
unlock the door. Activation depends
on the setting of the DIP switches 5
& 6 (Access during Communication
Failure).

=
Energized:
During a communication failure, the
normal state of the lock output is
Energized. When Lock #1 or Lock
#2 is activated, power is
removed
from the corresponding lock output to
unlock the door. Activation depends
on the setting of the DIP switches 5
& 6 (Access during Communication
Failure).
De-energized
: no power in normal
state; requires power to activate.

determines if OUT5 and OUT6 will
activate during a communication
failure. When DIP switch 7 placed in
the “ON” position, the OUT5 and
OUT6 outputs will activate. For example, the
buzzer on the readers can activate to advise
users that a communication failure has
occurred.
DIP Switch (8)
For future use.
EoL Jumper
Place the EOL jumper ON if the 2-Door
Expansion Module is at the beginning (Start
Point) or at the end (End Point) of the E-bus
Network (see Figure 2). Otherwise, place the
EOL jumper OFF.
