The Seco-Larm SM-226LQ is a magnetic contact for overhead doors and screens designed to work with closed loop circuits.

The SM-226LQ switch comes in a floor-anchored, cast-aluminum housing that's durable enough to withstand heavy vehicles passing over it. The magnet is installed in a gray ABS case that comes mounted on an L-shaped bracket. Wire leads are enclosed in a stainless-steel cable for maximum security.
