Fire Alarm
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.
Warwick (/ˈwɒrɪk/ WOR-ik) is a market town and county town of Warwickshire, England. It lies near the River Avon, 11 miles (18 km) south of Coventry and west of Leamington Spa and Whitnash. Its population was 31,345 in 2011. Signs of Neolithic activity precede unbroken habitation to the 6th century AD. It was a Saxon burh in the 9th century; Warwick Castle was built during the Norman conquest of England. Warwick School claims to be the country's oldest boys' school. The earldom of Warwick, created in 1088, controlled the town and built its walls, of which Eastgate and Westgate survive. The castle became a fortress, then a mansion. The Great Fire of Warwick in 1694 destroyed much of the town. Warwick missed industrialisation, but the population has grown almost sixfold since 1801.
