Components include: 
•  Panel. The panel circuitry is enclosed in a steel cabinet and is installed out of 
the way of household  or workplace traffic. The panel monitors all sensors and 
devices in the system and initiates a call to the central monitoring station in an 
alarm situation. 
•  Touchpads. Touchpads  let you communicate with and control  the system. 
You will use a touchpad to arm, disarm, and program your system. 
•  Door/window sensors. Door and window sensors protect the perimeter of 
your home by detecting when a door or window is opened. 
•  Motion sensors. Motion detectors in hallways  or individual rooms detect a 
person moving across the field of detection. 
•  Environmental sensors. Environmental  sensors, such as smoke, heat, and 
carbon monoxide detectors, remain alert for the presence of fire or carbon 
monoxide 24 hours a day.
