PUBLIC SIDE
This layout illustrates a
bi-directional traffic system with
controlled access entry (card
reader, radio control, etc.) and a
free exit loop. The gate is closed
by a CLOSE TIMER. The
timer to close starts when all
loops are clear. The timer is
adjustable from 1 to 90 seconds.
For an exit only system, the
FREE EXIT loop is replaced by
an additional OBSTRUCTION
loop.

E = 4ft (122cm) to 6ft (183cm). Vehicle
must be able to pass from one loop to the
next without loss of detection.
F = The distance from gate to FREE EXIT
LOOP is equal to the gate panel length
plus 4ft (122cm).
C = Maintain 4ft (122cm) min.
