Fire Alarm System
A fire alarm system warns people when smoke, fire, carbon monoxide or other fire-related emergencies are detected. These alarms may be activated automatically from smoke detectors and heat detectors or may also be activated via manual fire alarm activation devices such as manual call points or pull stations. Alarms can be either motorized bells or wall mountable sounders or horns. They can also be speaker strobes which sound an alarm, followed by a voice evacuation message which warns people inside the building not to use the elevators. Fire alarm sounders can be set to certain frequencies and different tones including low, medium, and high, depending on the country and manufacturer of the device. Most fire alarm systems in Europe sound like a siren with alternating frequencies. Fire alarm electronic devices are known as horns in the United States and Canada and can be either continuous or set to different codes. Fire alarm warning devices can also be set to different volume levels.
Huntingdon is a market town in Cambridgeshire, England, chartered by King John in 1205. Having been the county town of historic Huntingdonshire, it is now the seat of the Huntingdonshire District Council. It is well known as the birthplace of Oliver Cromwell, who was born there in 1599 and its Member of Parliament (MP) for the town in the 17th century. The former Conservative Prime Minister (1990–1997) John Major served as the MP for Huntingdon from 1979 until his retirement in 2001.
