The ABUS MK4200 Opening Detector for Steel Doors is a magnetic contact for protecting large (garage) doors - the unauthorised opening is detected and reported to the alarm panel. This opening detector is ideal for fitting to steel and metal doors - its special construction enables its use on these materials.
The detector consists of a magnetic contact (reed) and a magnet that are fitted parallel to each other. The electric circuit of this NC opening detector is normally closed (NC). If the distance between reed and magnet increases, the circuit is broken and an alarm reported. Its extremently robust aluminium housing protects it from damage even when driven over. The door opening detector for steel doors is VdS certified.
