4.123Mt Model 494 Locking Exit or

Entrance Gate

Description/Characteristics

The 3M Model 494 is designed to restrain patrons during an alarm. Gates are shipped from the factory to open with a clockwise rotation but may be modified to open with a counterclockwise rotation.

The locking mechanism is controlled by an alarm signal and power from the detection system.

When a strip is detected in the detection system and an alarm is created, the exit gate will lock in the closed position blocking patron travel through the exit corridor. The gate remains locked for the alarm period. If the gate is locked during an emergency, the gate arm can be forced open with a force of 15 - 25 lbs. [6,8 - 11,3 kg].

Gates are not available on the Detection System Model 3500.

Installation

Locking exit gates may be installed on either side of the detection system. For single corridor systems, the gate box may be located at the end of either panel. For dual corridor systems, two gates are required and the gate boxes must be located at the ends of the two outside panels.

The locking exit gate is designed to be installed by 3M factory trained service personnel.
