Arm will
remain up
while counting

the down loop.
Basic operator UP/DOWN cycle:
A. Valid UP command from the
access control device will raise arm.
B. Vehicle activating and clearing
the down loop will lower the arm.
Operator will
lower the arm
ONLY after the
last vehicle
activates
then clears
the down loop.
This option allows the access
control device and the barrier gate
operator to have multiple vehicles
in the area between them. The
operator will count all the valid
UP commands received and
require a down loop activation for
each one. The arm will lower only
after the last vehicle activates
then clears the down loop.
Remote transmitters are NOT
recommended for this option
because one vehicle’s remote
can accidently be pressed
multiple times which will get
counted by the operator as
multiple vehicles.
