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.
Bournemouth (/ˈbɔːrnməθ/ (audio speaker iconlisten)) is a coastal resort town on the south coast of England. At the 2011 census, the town had a population of 183,491. With Poole to the west and Christchurch in the east, Bournemouth is part of the South East Dorset conurbation, which has a population of 465,000.
Before it was founded in 1810 by Lewis Tregonwell, the area was a deserted heathland occasionally visited by fishermen and smugglers. Initially marketed as a health resort, the town received a boost when it appeared in Augustus Granville's 1841 book, The Spas of England. Bournemouth's growth accelerated with the arrival of the railway, and it became a town in 1870. Part of the historic county of Hampshire, Bournemouth joined Dorset for administrative purposes following the reorganisation of local government in 1974. Through local government changes in 1997, the town began to be administered by a unitary authority independent of Dorset County Council, although it remains part of that ceremonial county. Since April 2019 the unitary authority has been merged with that of Poole, as well as the non-metropolitan district of Christchurch to create the Bournemouth, Christchurch and Poole unitary authority.
The town centre has notable Victorian architecture and the 202-foot (62 m) spire of St Peter's Church, one of three Grade I listed churches in the borough, is a local landmark. Bournemouth's location has made it a popular destination for tourists, attracting over five million visitors annually with its beaches and popular nightlife. The town is also a regional centre of business, home of the Bournemouth International Centre or BIC, and a financial sector that is worth more than £1 billion in gross value added.
