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.
Weymouth /ˈweɪməθ/ is a seaside town in Dorset, on the English Channel coast of England. Situated on a sheltered bay at the mouth of the River Wey, 11 kilometres (7 mi) south of the county town of Dorchester, Weymouth had a population of 53,068 as of 2018. It is the third largest settlement in Dorset after Bournemouth and Poole.
The history of the town stretches back to the 12th century and includes roles in the spread of the Black Death, the settlement of the Americas and the development of Georgian architecture. It was a major departure point for the Normandy Landings during World War II. Prior to local government reorganisation in April 2019, Weymouth formed a borough with the neighbouring Isle of Portland. Since then the area has been governed by Dorset Council. Weymouth, Portland and the Purbeck district are in the South Dorset parliamentary constituency, which elects one Member of Parliament: as of 2021, the Conservative Richard Drax.
A seaside resort, Weymouth and its economy depend on tourism. Visitors are attracted by its harbour and position, halfway along the Jurassic Coast, a World Heritage Site, important for its geology and landforms. Once a port for cross-channel ferries, Weymouth Harbour is now home to a commercial fishing fleet, pleasure boats and private yachts, while nearby Portland Harbour is the location of the Weymouth and Portland National Sailing Academy, where the sailing events of the 2012 Olympic Games and Paralympic Games were held.
