Magnetic alarm contacts are the first line of defense in your security system. They are inexpensive, very reliable, and in most cases out of sight. Alarm contacts should be used on all doors and windows. The most basic sensors of any alarm system is a door and window Magnetic Contact Switch. This type of contact switch is for normally closed circuits; this means that the when the magnets are lined up with the switch the circuit is closed. Move the magnetic away from the switch causes the sensor to open. The security panel sees this, and if the system is armed, an alarm will occur. When it comes to alarm contacts you can trust the WINN brand security products.

I was able to put the end of line resistors inside of these little sensors. I used some shrink wrap tubing to hide the splices. Comes with the necessary screws to attach. (Posted on 10/17/11)
