![]() ![]() If a detector is activated, the control panel identifies the circuit that contains the triggered device and so indicates the zone from which the fire alarm has originated, but the area then has to be manually searched to pinpoint the individual device. A separate two-core, fire-protected cable for each alarm sounder or bell is needed because they are wired to different loops. There may be multiple detectors on a single zone. Less expensive to purchase than other types of alarm system, they work by dividing the building into a number of detection zones, with the detectors and call points within each zone hardwired on dedicated circuits to the control panel. Analogue addressable fire alarm systemsĬonventional, or four-wire, fire alarm systems have been extensively used in smaller properties such as shops and restaurants for many years.They may be also divided into categories depending on whether their aim is to protect life or property, or whether they are manual or automatic. The wide choice of fire alarm systems available is broadly divided into “conventional” fire alarm systems and analogue addressable “intelligent” systems, each type best suited to different kinds of premises. Guidance on the design, installation and maintenance of fire alarm systems can be obtained from code of practice BS:5839. Based on the findings of this assessment, they must ensure that adequate and appropriate fire safety measures, including fire detectors and alarms, are in place to minimise the risk of injury or loss of life in the event of a fire. ![]() Fire alarm systems are essential for the protection of life and property and are a legal requirement under the Regulatory Reform (Fire Safety) Order 2005 in most non-domestic premises where people work or visit, such as offices, shops, hotels, public venues, and in almost all new buildings under the 2010 Building Regulations.īy law, employers and/or building owners or occupiers must carry out, and keep updated, a fire safety risk assessment. ![]()
