PROGRAMMABLE AUXILIARY RELAYS - Easily add additional features, such as warning lights/alarms.
PRE-MOTION WARNING ALARM - Activates onboard alarm three seconds prior to gate motion.
MECHANICAL BRAKING SYSTEM - Adds substantial gate position control at all points in travel. This
solenoid-actuated brake system also prevents the gate from being back-driven.
MAXIMUM RUN TIMER - Protects against damage to the gate and operator by limiting the unit’s runtime to 120 seconds.
EXTERNAL ALARM RESET BUTTON - Allows for quick reset of the gate operator when the alarm has been activated.
ADJUSTABLE FRICTION CLUTCH - Helps to protect gate and operator from damage should the door meet an obstruction.
ANTI-TAILGATE - Prevents unauthorized access. Gate will pause when closing as vehicle pulls onto interrupt loop or breaks photo beam. Once vehicle backs up, gate will continue to close.
QUICK CLOSE - Closes the gate immediately after a vehicle pulls off the interrupt loop.
