In addition to the 325 standard, vehicular gate operators must also be tested to UL 991; Tests for Safety-Related Controls Employing Solid-State Devices. The UL 325 Standard has undergone significant revisions over the past several years. The purpose of the revisions is to create entrapment prevention criteria for vehicular gate operators and systems, and to increase over-all safety of the product.
The standard also calls out for specific construction specifications for the vehicular gate itself (see ASTM F2200-02). The revised standard was first published Sept. 18, 1998, and went into effect March 1, 2000.
Secondary entrapment prevention device or devices are installed in areas where an entrapment hazard exists. These devices include contact (electric edges) and non-contact (photo-electric) sensors.
Warning signs are placed in an area where they are visible from each side of the gate.
Gate controls are installed in such a manner that a person operating the controls cannot come in contact with the gate or gate operator.
The gate operator needs to be appropriate for the construction and class of the gate. Rollers should be guarded. Pinch points should be eliminated or guarded.
All openings in slide gate systems are guarded or screened from the bottom of the gate to a minimum of 48 inches above the ground to prevent a 2.25-inch diameter sphere from passing through the openings anywhere in the gate, and in that portion of the adjacent fence that the gate covers in the open position.
Refer to ASTM-F2200-02 for more information on the construction of the gate and associated hazards.
The Model 9100 sliding gate operator is designed to operate vehicular slide gates in residential and commercial applications. It can easily be mounted in the front, center or rear of the gate without any costly and time consuming field modifications. In addition, the operator can be pad- or post-mounted to meet any installation requirements.
DoorKing vehicular gate operators have been designed to exceed the requirements set forth in UL 325 with their mission statement to offer the safest vehicular gate operators on the market.

DOOR KING microPLUS®
DoorKing MicroPLUS RF controls provide a high level of security because coding and encryption schemes are unique to DoorKing, resulting in transmitter codes that cannot be duplicated or copied. Therefore only the original intended transmitter will activate your access system. The 8056 ‘looks’ like any other Wiegand reader, and the transmitters are managed (enrolled deleted, tracked) just like any other credential.
PROXmitters combine RF control with a proximity tag to provides remote operation of vehicular access gates from the safety and convenience of a vehicle.
MicroPLUS® transmitter codes cannot be copied assuring that only the original intended transmitters will activate the access control system. More than 286 million transmitter codes are available plus an encrypted “sync” code that changes every time the transmitter is used.
Features of the 8056 receiver include:
Weigand output receiver.
Supports up to 5300 transmitter codes.
Output data in 26, 30 or 31 bit formats.
12-24 volt, AC or DC.
MicroPLUS Transmitter features include:
Make sure the site is prepped and the gate itself is operating well, then carefully select the right equipment. In this case the DoorKing 9100 and BEA remote filled the bill.
