In 2006, Greater Manchester fire crews spend over 97,000 hours dealing with the 13,500 false alarms from automatic fire alarms. In an attempt to slash the £2m cost of false callouts to business premises, crews will no longer respond to automatic fire alarms if there is no sign of a blaze. In future, any alarm generated by an automatic detection system will be ignored unless it is confirmed as a real fire after human investigation. The move is primarily aimed at commercial premises; hospitals, hotels, prisons and other high-risk buildings will be excluded from the new policy.
