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.
Rhyl (/rɪl/; Welsh: Y Rhyl, pronounced [ə ˈr̥ɨl]) is a seaside resort and community in the Welsh county of Denbighshire. It lies within the historic boundaries of Flintshire, on the north-east coast of Wales at the mouth of the River Clwyd (Welsh: Afon Clwyd). To the west is the suburb of Kinmel Bay and the resort of Towyn beyond, to the east Prestatyn, and to the south Rhuddlan. At the 2011 Census, Rhyl had a population of 25,149, with Rhyl-Kinmel Bay having 31,229. The Abergele–Rhyl–Prestatyn conurbation numbers over 60,000. Once an elegant Victorian resort, an influx from Liverpool and Manchester after the Second World War changed the town's face. It had declined sharply by 1990, but has since been improved by major regeneration investments. Several million pounds of European Union funding to the Welsh Government has gone on developing the seafront.
