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.
The Metropolitan Borough of Dudley is a metropolitan borough of West Midlands in England. It was created in 1974 following the Local Government Act 1972, through a merger of the existing Dudley County Borough with the municipal boroughs of Stourbridge and Halesowen. The borough borders Sandwell to the east, the city of Birmingham to the south east, Bromsgrove to the south in Worcestershire, South Staffordshire District to the west, and the city of Wolverhampton to the north.
Being a metropolitan borough Dudley is effectively a unitary authority, with the exceptions of Transport for West Midlands, (publicly branded as West Midlands Network), fire and police services, and the local government pension fund (West Midlands Pension Fund), which are jointly run by the seven metropolitan boroughs of the West Midlands county.
For Eurostat purposes, Dudley is a NUTS 3 region (code UKG36), and is one of seven boroughs or unitary districts that comprise the "West Midlands" NUTS 2 region.
