Fire Detectors for unmanned machinery spaces
Fire protection on ships is provided by detection and fire-fighting equipment together with structural features which are intended to contain an outbreak of fire and the employment when required of non-combustible materials to prevent its spread.
The use of fire detectors is increasing, particularly with the tendency to
reduced manning and unmanned machinery spaces. A fire, if detected
quickly, can be fought and brought under control with a minimum of
damage. The main function of a fire detector is therefore to detect a fire
as quickly as possible; it must also be reliable and require a minimum of
attention. An important requirement is that it is not set off by any of the
normal occurrences in the protected space, that is it must be
appropriately sensitive to its surroundings. Three phenomena associated
with fire are used to provide alarms: these are smoke, flames and heat,
