Standard Features
Inherent obstruction sensing
This unit's internal obstruction sensing system offers a single force adjustment for both the open and closed directions. If the gate strikes an obstruction, a closing gate will reverse to open and an opening gate will reverse to close.
External obstruction sensing
Input connections are provided for external contact and non-contact sensors, such as photo eyes and edge devices.
Advanced dual gate operation
This convenient 2-wire system allows the operation of 2 separate gate operators in unison at a single entrance. This advanced system provides the added convenience of
connecting accessories to either operator.
Sequenced access management
The Sequenced Access Management (SAM) system provides the capability to sequentially control the operator in tandem with a barrier gate.
Digital logic control
Supports long-distance control wiring runs of over 1,000 feet, providing you greater flexibility of gate operator site placement.
LED indicators
Operator input, status and diagnostic LEDs simplify setup and troubleshooting.
Warning device
UL325-compliant entrapment warning alarm has the ability to be set for pre-operation warning. This will provide a 3-second warning prior to and during gate movement.
Loop detector inputs
A full range of inputs are available to support exit, shadow and interrupt loop detectors.
Timer to close
Adjustable timer can be set from 1 to 180 seconds. The unit will automatically reset upon receiving any additional open commands.

Maximum run timer
Protects against damage to the gate and operator by limiting the unit's run time to 120 seconds.
Emergency stop button
This 1-button station will halt movement of the operator in an emergency situation and comes standard in an outdoor weather - tight enclosure.
Maglock control
A dedicated control relay is provided to activate and deactivate an optional magnetic lock for securing the gate.
Gear drive reduction
The wormgear 30-to-1 reduction unit is saturated in an oil bath for strong fluid motion of the operator.
Control inputs
Control inputs allow the connection of a full range of optional external devices like loop detectors, telephone entry systems, access control systems and radio receivers.
Limit settings
All driven limit cams are fully adjustable, adding considerable convenience to unit installation and maintenance.
Surge & spike protection
Specially designed circuitry provides excellent protection from external spikes or surges.
Manual disconnect
Ensures that manual operation is possible during emergencies and maintenance work.
Removable access control panel
A removable access door is incorporated into the design to provide easy access to the electronics when programming and for maintenance.
