As directed by the HSE (Health & Safety Executive) the law requires electrical equipment to be maintained to prevent danger. The type and frequency of user checks, inspections and electrical testing needed will depend on the equipment, the environment in which it is used and the results of previous checks.
Life safety systems should be an integral part of any building's infrastructure. It is these systems that monitor and and indicate the presence of smoke or fire. Ensuring the system you have is adequate for your property and suitably maintained can save lives.
