Fire alarms are an essential part of any building's safety system, and it is crucial that they are regularly inspected to ensure that they are in good working order. BS 5839 recommends that fire alarm systems be inspected at least every six months by a 'competent person', usually a specialist fire safety company. This professional testing will cover factors including, but not limited to: logbook inspection, visual call point inspections, visual inspection of detectors and other devices, inspection of any building changes (layout, alterations), and changes to use or occupancy levels. Failure to meet the six-month inspection quota means that your system will not be deemed compliant with British Standards, something which could cause issues if you are tasked with proving that your building meets required fire safety regulations. Therefore, it is important to ensure that your fire alarm system is regularly inspected by a competent professional in order to maintain compliance with BS 5839.
