Central stations monitor every type of emergency situation you can think of. The list ranges from fire alarms to burgular alarms, emergency medical conditions, panic alarms, carbon monoxide detectors, temperature, water level, etc. Once a sensor detects a change in circumstance, the contracted central station can monitor it and direct the proper response. Here are a few of the more unusual applications:
Agricultural - After experiencing a number of explosions, a hog confinement center in the Midwest installed a special gas detector to report high concentrations of methane.
Industrial - A photo processing plant monitors dozens of variables, including ambient heat and light, to safeguard the quality of its product - your family's photos.
Commercial - A store in a high-crime area signals the central station when it opens and closes. Its system uses listen-in and talk-back microphones to protect both property and personnel.
Residential - The common home alarm system senses not only intrusion and fire, but also water in the basement, low temperature and carbon monoxide. While the family vacationed, the heat in their home failed and a water pipe burst. The water sensor activated a digital communicator, notifying the central station, which called a neighbor with a key. A plumber was called and the family returned to a warm, cozy and dry home.

Partition
This is the process of splitting your alarm system in two or more "partitions," arming and disarming each area seperately while using only one phone line, and paying only one monitoring fee. Many small businesses use a system with this option. For example, a homeowner has a garage or work area that is not attached to his house, but wants to arm that area seperately while he is at home. Each partition can have its own keypad, or one keypad can be used to access each partition. The monitoring company will know which partition is sending the alarm, and will send the authorities to the appropriate area of the house/business.
