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.
Lowestoft (/ˈloʊ(ɪ)stɒft, ˈloʊstəf/) is an English North Sea coast town and civil parish in the county of Suffolk. On the edge of The Broads, it is the most easterly UK settlement, 110 miles (177 km) north-east of London, 38 miles (61 km) north-east of Ipswich and 22 miles (35 km) south-east of Norwich. As the main town in the district of East Suffolk, it had an estimated 73,775 inhabitants in 2018. A port town, it developed out of the fishing industry and as a seaside resort with wide, sandy beaches. As its fisheries declined, oil and gas exploitation in the southern North Sea in the 1960s added to its development, alongside nearby Great Yarmouth. These roles have declined, but it is developing as a regional centre of the renewable energy industry.
