The BSD-3011 Series Overhead Door Contacts are exclusively designed for rugged high traffic installations.
The BSD-3011 Series magnet is mounted on an adjustable L shaped bracket designed for greater flexibility, universal mounting, greater pulling power, and to provide a professional installation appearance.
The BSD-3011 housing is extruded from aluminum material and tested to withstand a crushing force of 20,000 pounds or 10 tons without harming the delicate reed switch. All mounting hardware including lead anchors are provided as well as a mounting bracket for the actuating magnet.
Use this heavy-duty magnetic Garage Door Contact Switch on garage doors, roll-up doors and other doors or gates where it may be difficult to mount regular magnetic contacts. Smaller magnetic switches have a small operating gap where the contact and magnet must be within half an inch for reliable operation.
The floor mount units are constructed with a low profile heavy cast aluminum housing.The reed switch assembly is fully encased in Security’s exclusive polyurethane potting material to prevent damage due to moisture or humidity. A wide operating gap distance of up to 2 3/4" inches makes installation easy and helps prevent false alarms caused by door movement or damaged and loose fitting doors.
Bottom mounting has been the most common method used for overhead doors in the past, and can still be a good option. The contact is secured to the concrete floor using plastic anchors and screws.The magnet attaches to the bottom rail of the overhead door with screws, or with bolts and nuts..
