ENTRAPMENT PROTECTION INSTALLATION
Ÿ
A minimum of (2) monitored entrapment protection devices are
REQUIRED
for each entrapment zone.
Ÿ
An entrapment zone is a location or point of contact where a person can become entrapped between a moving
gate and a rigid object.
Ÿ
The operator is equipped with an inherent entrapment protection system (ERD).
Ÿ
The gate operator requires an external monitored entrapment protection device (non-contact photoelectric
sensor or contact edge) for each entrapment zone prior to gate operation. The operator cycles power to the
external entrapment protection device and checks for device signals. If the operator does not receive the
correct feedback from the device, the gate will not operate.

SAFETY LOOP
—
Below is a typical loop layout. When connecting to an All-O-Matic circuit board, use the following:
—
SAFETY LOOP - Normally Closed (N.C.) Contacts
—
EXIT/OPEN CMD - Normally Open (N.O.) Contacts
(See page 22 for LPR-1 loop rack wiring)
—
Loop wires
MUST
be twisted from the exit point of the loop saw cut to the gate operator.
—
Twist loop wires 6 turns per foot, as shown below. Improper twisting of wires can cause loop issues.
—
When using an inside and outside safety loop, loops must be
