Frequently Asked Questions About Commercial Fire & Security
Q: What fire alarm system does my business need?
The type of fire alarm system required depends on the size, layout, use and fire risk of your premises. A professional assessment can determine the appropriate detection, alarm coverage and system category for your building.
Q: How often should a commercial fire alarm be serviced?
Commercial fire alarm systems should generally be inspected and serviced at least every six months by a competent person, alongside the routine checks carried out by the responsible person for the premises.
Q: Is a fire alarm a legal requirement in a commercial property?
UK fire safety law requires businesses to have appropriate fire detection and warning arrangements based on their fire risk assessment. The exact system required will depend on the premises and the risks identified.
Q: What is the difference between conventional and addressable fire alarm systems?
Conventional systems divide a property into detection zones, while addressable systems identify the individual device that has been activated. Addressable systems are often suited to larger or more complex commercial buildings where quickly locating an incident is important.
Q: How often should emergency lighting be tested?
Emergency lighting requires regular testing to ensure it will operate correctly if the normal power supply fails. This typically includes monthly functional checks and a full-duration test annually.
Q: Does my business need an AOV or smoke ventilation system?
AOV and smoke ventilation requirements depend on the design and use of the building. They are commonly used in areas such as stairwells, corridors and communal spaces to help remove smoke and heat and keep escape routes clearer during a fire.
