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.

Worked well with my Honeywell alarm systemReview by Doug
This contact works great for my home garage door. It works like any magnetic electrical contact except it has a much greater tolerance on spacing. The magnet supplied will close the contact from over 2 inches away. This makes up for any variations in the door position. I opted to mount mine at the top of my garage door rather than the floor and it works great. (Posted on 4/26/15)

I have been installing these switches for over a year and have yet to have one fail. They outperform any switch I have been using or installing for ten years. The are rugged and hold up to constant use. You can't go wrong with these.
