Honeywell 944T-WH Overhead Door Contact Alarm Sensor

The Honeywell 944T-WH is a purpose-built overhead door contact designed to monitor the open and closed status of large overhead and rolling doors in commercial and industrial security installations. Unlike standard door contacts intended for hinged or sliding doors, this unit is engineered to accommodate the unique geometry and movement of overhead door panels, ensuring reliable detection even where conventional contacts would fail to maintain consistent alignment. It integrates cleanly into hardwired intrusion detection systems, providing a supervised signal path that security panels and access control platforms can monitor continuously. For professional installers working in warehouses, loading docks, auto dealerships, self-storage facilities, and similar environments, the 944T-WH delivers the trusted Honeywell build quality expected in life-safety applications — contributing to a complete perimeter protection strategy without compromising the integrity of the secured opening.
