Abstract: The invention relates to an alarm siren detector and a method of actuating a locking mechanism on detecting the alarm siren. The alarm detector (10) comprises a locking mechanism (22, 24, 26) comprising a locking arm (26) which is moveable between a locking position and an unlocking position and movement of the locking arm between an unlocking position and a locking position is user operated. The method comprises detecting and sampling environmental sounds with a microphone; comparing the sampled sound with a reference pattern using fuzzy logic to determine whether an alarm is sounding; and if it is determined that an alarm is sounding, releasing the locking mechanism so that the locking arm automatically moves from its locking position to its unlocking position. An application of the invention to a fire door enables it to be held open legally, since the door will close automatically as soon as a fire alarm is triggered.
