Alarm contacts allow you to secure the most vulnerable parts of your house -- the doors and windows. By installing hardwired contacts you can make sure that your alarm system keeps an eye on any locations where an intruder might force their way in. Recessed, surface mount and specialty sensors give you the option to choose the exact type of contact you need for your application.

Sentek has over 50 door and window contacts for you to choose from for your wired or wireless home alarm system. Typically a home burglar alarm system kit comes with two door and window contacts, but that might not be enough to fit all your home security needs.

Door and window contacts work with a sensor and a magnet. The sensor is placed on the frame of the door or window, while the magnet is placed on the door or window itself. This creates a circuit between the two. However, when the circuit is broken by opening up the window or door, a signal is sent to the alarm control panel that an entry has been breached.
