Alarm Contacts-Contact switches are magnetic switches used to protect doors and windows for the most part. There are three styles that are used by most alarm companies. It is closer contacts, surface mount contacts and roller-ball contacts.
Closer contact in the tracks window and door jams hidden, so that can not be seen when the window or door is closed. The switch is located on the fixed or non-moving opening and a magnet is placed on the moving part.When the magnet meets the switch the circuit is completed and the controller knows that it is closed. Recessed contacts are more complicated to install, unless they are placed during the construction of your home or office. A good plumber can install recessed contacts in the home after the building until you have a basement unfinished attic or utility room with access to the wires run
Contact surface of the same function in depth, but those are visibleif the doors or windows are closed. They are available in three sizes too big, small and micro enterprises. They are available in white, gray and brown, to blend with the door panels or window sill they are mounted.
Roller-ball contacts are on the side of the hinge is pushed the door jam and the spring ball, when the door closes the circuit. These are likely to need replacing in a few years, since they move as one part.
All types of recessed lightsand surface mount contacts can be directly wired to your control panel or you can add a wireless version to get. Wireless contacts have a transmitter tied to them or built into them that sends a radio signal to a receiver in the control group. The transmitter is mounted and is available in two colors, white and brown. If not the white and brown colors you want, you can paint to match your decor switches and transmitters.
The doors are the most common entry point and mustprotected by the system. Council always in contact with every door in your home or business perimeter
Contacts window can be up quickly, since most homes have many windows. I always thought that the window of the working contact with the owner a false sense of security due to the fact that a window be opened for them to have. If the window is locked (and should) if you are away or asleep, a thief has to break the glass or remove the glass to unlock it. If you breakglass and the alarm does not know why they should open the window? Instead, most likely clear the broken glass and climb in. So your money is better spent on motion detectors and / or glass-break detectors sound.
If you have children, window contacts can be a valuable tool. They will keep your children to open the window for a stranger. It will also be regretting your teenager that you always read them. (If they say they want is the feastContact Window magnet, the jigs up!) Are often better than the people in them to keep out intruders. If you are using for the contacts window, could be the fact that the surface mount versions can be constructed so that always open the window a few inches for ventilation and still be armed.
