EdgeAlert™ signals an open gate with flashing LED lights and a highly audible alarm. The amber-colored LEDs are located on the front and back of the enclosure, providing high visibility at elevated and ground levels. When a gate is being used for daily activities, workers may choose to silence EdgeAlert™ for 120 seconds by pressing the snooze/acknowledge button. Once an open gate has been closed and secured, users can reset the EdgeAlert™ alarm by pressing “Snooze/Acknowledge”, or opt for automatic reset mode.

Use with Mezzanine Platform Access Gates:
