The fire alarm system is a very important aspect of any domestic and business setting. Fire alarm systems are essential for the protection of life and property and crucial to get a fire alarm system installed in your vicinity as a precautionary measure against accidental fires. According to 2010 Building Regulations, installation of fire alarms or fire detectors 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. Hence, any employers or building owners or occupiers must carry out, and keep updated, a fire safety risk assessment, and based on the findings of this assessment, they must ensure that appropriate fire safety measures, including fire detector system and alarms, are in place to minimize the risk of injury or loss of life in the event of a fire.
