The robust aluminium opening detector for steel doors is a magnetic contact for protecting large (garage) doors. Unauthorised opening is detected and reported to the alarm centre.
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. These are fitted parallel to each other. The electric circuit of this NC opening detector is closed in normal state (NC). If the distance between the reed and the magnet increases, the circuit is broken and an alarm reported. Its extremently robust aluminium housing protects it from damage when driven on. The door opening detector for steel doors is VdS certified.
