As I visit more and more sites, I am finding a neglect towards the maintenance and upkeep of fire doors and their interface connections to fire alarm systems.
Fire doors wedge open with fire extinguishers or any other object that may happen to be near by is a criminal offence.
However, they are properly and legal ways of holding open a fire door. The most popular is provided a door magnet and this magnet is kept energised by the fire alarm system. The principle is the same whether it is a wired or wireless fire alarm. Another popular method is the dorguard. This unit is operated by the sounder of the fire alarm system. The dorguard looks for a constant noise (longer then 30s )over a certain decibel level and if these criteria’s are met the dorguard operates.
Fire alarm maintenance of the fire alarm and door holders is crucial to ensure the passive fire prevention throughout the building.
Surrey based fire alarm company Fire Systems Ltd, provides fire alarm installation and fire alarm maintenance.
How comprehensive do Fire Detection Systems need to be? Would an integrated solution be needed or simply the correct application of a fire alarm and fire extinguishers for most office and domestic sites?
