-  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
