FAQ:

Q: How do magnets work in alarm systems?

A: Some sensors rely on magnets to create the connection. When the two parts of the sensor are separated, the magnetic field is broken and the alarm goes off. Others rely on a light beam, with one piece of the sensor generating the light and the other receiving it.

Q: How does a door sensor work?

A: Door sensors work because they use a sensor and a magnet. The sensor is placed on the door frame and the magnet on the door itself. A circuit attached to the magnet sends a message to the alarm when the current is disturbed when the door is opened.

Q: What is a wireless door sensor?

A: With a 10+ year maximum life battery and advanced circuit design, the wireless door/window sensor provides effective security that’s easy to set up. Two-axis sensing and wireless technology make installation simple, even in tight spaces. The door/window sensor also features an optimized internal antenna design to increase range performance.

Q: How do alarm system door switches work?

A: Most car alarm systems utilize the switching mechanism that is already built into the doors. In modern cars, opening a door or trunk turns on the inside lights. The switch that makes this work is like the mechanism that controls the light in your refrigerator.
