Garage Door Contact Sensor

Monitor doors remotely with magnetic closure sensors. The GRI-4701-A sensors are designed to eliminate false alarms that are common with standard floor switches getting damaged by fork lifts or other equipment. The contacts are moved up onto the track and out of the way of heavy equipment. These sensors are easy to install and very adjustable. They can attach to a variety of track sizes and can be installed on either side of the door. The sensors can have a gap of up to 3 inches which means mis-alignment due to wear and tear on the door is not a problem. The sensor offers form C contacts so both NO and NC circuits are supported.

The GRI-4801-A can be connected to any ControlByWeb product with a digital input.
