What is an Alarm System?

An alarm system is an electronic installation that consists of input and output devices, a control panel, and their respective wiring. Their purpose is to minimize loss from burglary, fire, and vandalism, as well as to warn building occupants of a potentially hazardous situation. These warning devices include carbon monoxide detectors, smoke alarms, and security systems, among others.

What does a common home alarm system include?

A typical home alarm system consists of a number of devices placed at doors to a home to detect when the door has been opened. The alarm will sound when the system is activated. Similar contacts are placed on or near windows and will trigger the alarm if the glass is broken to gain entry. The key parts of a home alarm system are:

The control panel. This is the main hub for the system’s wiring. It contains the backup battery, and is where the phone lines are connected if the system is monitored.

The keypad. This allows for arming and disarming the system, usually through input of a numerical code.

The siren. Triggered when the system detects an intruder, it can be visual, aural, or silent sending a signal to the monitoring agency – depending on where the system is installed and whether catching the intruder is a priority.

Motion detectors. These are used to sense changes in a room due to a human presence while the system is armed. Special detectors can be installed in homes that have pets.

Door and window contacts. As mentioned, these sense when a door is opened or a window is opened or broken, and will trigger an alarm if the system is armed.

If an alarm is triggered, a monitoring company (staffed 24 hours a day) will attempt to contact the homeowner, and then the police, fire station, or ambulance as necessary. These companies usually charge a monthly fee; though an alarm system can be used without a monitoring company, it is a good idea to retain one in case of an emergency.

An alarm system is set up in a fairly basic way that allows the owner to arm and disarm the system as needed, as well as disable the alarm if a false positive occurs. Though an unmonitored alarm system comes equipped with lights and a siren, it also relies on neighbors to contact the police in case it is set off; typically, it is a good idea to allow the system to be monitored, thereby ensuring that the authorities will be contacted in a timely fashion after an event occurs.

How does it work?

Alarm monitoring is quick and detailed communication between your home security system and the central station of your security provider. Your control panel registers an emergency event and sends a signal to the central monitoring station, where the appropriate authorities are notified and sent to your home.The technical specifics may be slightly different for each security provider, but the basics of alarm monitoring is similar in any home security system. Your system control panel is the center of a network of sensors, which may include window or door sensors, motion detectors, tamper sensors on the telephone box, or specialized temperature, flood, and smoke detectors. When your system is armed and any of these sensors are triggered, a signal is sent to the monitoring station-typically via your telephone line, although some alarm monitoring systems also offer alternate or backup transmission options.The first signal sent by your control panel will alert monitoring personnel at the central station, who will call to notify you and confirm whether it’s a real emergency or a false trigger. If you don’t respond, the alarm monitoring service contacts the proper agency to dispatch emergency personnel to your address. Some security systems offer additional features, such as immediate alarms, which don’t depend upon a confirmation call or silent alarms that don’t alert intruders and give them a chance to disable the system before the follow-up signal is sent.

Critical information is sent by your home security system to the alarm monitoring center, including account identification (to access your address and contact information) and the type of sensor that has been triggered.

For example, a smoke detector event will cause the alarm monitoring service to contact the fire department, while the signal from a medical alert pendant will be routed to ambulance or paramedic services.

Unmonitored “local” alarms do provide some important benefits. If you’re home, the alarm noise lets you know that there’s a problem and allows you to take necessary action. The noise may even frighten off some less-determined intruders, but most will simply ignore it and disarm your control panel as soon as possible. Many emergencies are too serious for you to deal with by yourself, especially if you’re disabled or otherwise incapacitated; in most cases, you’ll want police, fire, or medical professionals on the scene as soon as possible.
