Rules mount magnetic contacts strong> td> tr> tbody> table> The
opening contact consists of a magnet and the magnetic field creating a contact whose state is changed by the presence of this field. In the air or neutral materials (wood, aluminum, plaster ...) the magnetic field is distributed uniformly around the magnet. A near ferromagnetic materials (steel, soft iron) the magnetic field of the magnet is fully attracted and captured by this material and no longer acting in other directions.
Therefore, it is necessary to remove enough magnets and magnetic media contacts using special spacers. To verify that material is ferromagnetic or not, use the magnet contact. If there is attraction between the magnet material, it is ferromagnetic.

a> td> tr> tbody> table > Principle of operation of a magnetic sensor opening NC (normally closed)

Opening detectors are used on or from the access to be protected.

Each detector consists of two parts:

a contact mounted on the frame and a magnet on the movable part.

The contact is a reed switch (reed contact or ILS). When the magnet is removed from the ILS, the contact thereof is open. The panel receives information as synonymous with an opening door or window open, if the security system is activated, the alarm goes off. When the magnet approaches the contact, the two blades of the ILS are subjected to the magnetic field. Each blade behaves like a magnet. The flexible blade is deformed and comes into contact with the rigid blade. The electrical contact is established and the control unit receives information as a closure. In this case the alarm will not be triggered. The most used contacts are NC = normally closed and open on alarm. These contacts must be connected in series with a normally closed area of ??your control panel. Big advantage of these contacts is that the opening of one or the cable cut off the alarm.

There are two types of detector opening (NC and NO):

- Magnetic sensor opening NC (normally closed contact = no alarm contact open on alarm)

- Magnetic sensor opening NO (normally open contact = no alarm contact closure alarm)
