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.
