SENSOR: The actual alarm sensor, detector, or device installed to detect an
intrusion, fire, or environmental problem. Examples include: door contacts, window contacts, motion sensors, glassbreak sensors, smoke detectors, rate-
SILENT CONDITION: Most types of alarms and troubles alert you with the keypad sounder and the sirens, horns, or speakers located in your premises. The intent is to advise you of the alarm or trouble and allow you to respond promptly. The audible sounds also let intruders know that they have been detected and will hopefully scare them away. In circumstances in which an audible alarm might put your life in danger, those alarms are programmed as silent conditions. For an example, see DURESS.
SYSTEM: Your security system is composed of three main parts: 1) the control panel that functions as the system brain and the link to the monitoring agency (central station); 2) the keypad(s) that inform you of system status and allow you to input commands; 3) security sensors, such as door and window contacts, motion sensors, smoke detectors, and other sensors, to detect intrusion, fire, and other conditions as needed for your premises.
