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.
Leicestershire (/ˈlɛstərʃər, -ʃɪər/ (About this soundlisten); postal abbreviation Leics.) is a landlocked county in the English Midlands, being within the East Midlands. The county borders Nottinghamshire to the north, Lincolnshire to the north-east, Rutland to the east, Northamptonshire to the south-east, Warwickshire to the south-west, Staffordshire to the west, and Derbyshire to the north-west. The border with most of Warwickshire is Watling Street, the modern A5 road.
Leicestershire takes its name from the city of Leicester located at its centre and administered separately from the rest of the county. The ceremonial county – the non-metropolitan county plus the city of Leicester – has a total population of just over 1 million (2016 estimate), more than half of which lives in the Leicester Urban Area.
Leicestershire remains the only county in England other than Greater London that has yet to adopt an official county flag.
