Mh3>Basics Of Burglar Alarm Equipment
Security and burglar alarms have been use for many years. Many businesses use burglar alarms as well as some private residences. The technology has changed a great deal over the years, but the basic components of burglar alarm systems are still the same. Three basic types of components make up burglar alarms.
Sensors are the first part of burglar alarms to be activated when an alarm condition exists. While once the sensor was as simple as a string or wire attached to a door or window rigged to make noise upon opening. Today's sensors are far more sophisticated affairs. They can vary from simple switch type sensors that create an open circuit when a door or window is opened and the two halves of the sensor are separated. More advanced sensors are available today that use motion detection, heat, proximity, and even lack of motion. Some even utilize laser light to form a circuit.
The second component of burglar alarms is the signaling device. These components, like sensors, have evolved as time has passed. Where once signals were just some cans or bells attached to a string, today, they are very sophisticated pieces of equipment. Many signal devices include a loud whistle or siren and strobing lights designed to act as a deterrent. The assumption is that the hoorah will frighten a criminal and stop burglary before an intruder actually gains ingress. Other types of signaling components are silent. These typically send a radio signal to a monitoring station or directly to emergency response agencies.
Some signaling devices incorporate both parts. An audible and/or visible alarm is generated to let the owner's know something is wrong. At the same time a radio signal is sent to emergency response personnel to alert them to the situation. Burglar alarms that incorporate fire alarms and emergency medical alerts use both types of signaling device.
The third and most commonly recognized component of burglar alarms is the control panel. These panels have changed somewhat since the first models were built, but all function in basically the same manner. A typical control panel allows the owner to enter codes to turn various parts of the system on or off and tell the system whether the owner is home or not. Standard procedure calls for the owner to enter a code when leaving home that arms the entire system after a set delay built in to allow the owner time to leave the building. Upon returning, the owner will trip the alarm on entry. Even very basic systems will allow a set length of time for the owner to disarm them before notifying either a monitoring company or the police. Very sophisticated systems will only delay on specific sensors recognized as normal access points.
Fire alarms and medical emergency alerts will automatically send out a notification to proper authorities.
Burglar alarms have changed and grown over time. Even with all the changes and additions, the basic components that make up the systems continue to be of three basic types. Sensors, signaling devices, and control panels are the three types of components included in burglar alarms.
