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.

​Swindon (/ˈswɪndən/ (listen)) is the largest town in Wiltshire, South West England, lying between Bristol, 35 miles (56 kilometres) to the west, and Reading, the same distance to the east. The town is 71 miles (114 km) west of London. The population of the Swindon built-up area was 185,600 in 2011.[1]

The Town Development Act 1952 led to a major increase in its population.[2]

Swindon railway station is on the line from London Paddington to Bristol. Swindon Borough Council is a unitary authority, independent of Wiltshire Council since 1997. Residents of Swindon are known as Swindonians. The town is home to the offices of English Heritage, the Historic England Archive (formerly the National Monuments Record Centre) and the headquarters of the National Trust (all three are on parts of the site of the former Great Western Railway's Swindon Works), and the head office of the Nationwide Building Society.
