ADAPTIVE METHOD OF FIRE ALARM Russian patent published in 2013 - IPC G08B17/00 G08B19/00 

FIELD: fire-prevention facilities.

SUBSTANCE: method is implemented by means of selection (adaptation) of threshold values of the controlled factor of fire, depending on the values of the controlled operational parameters that characterise these modes of operation of the process environment in which the undesirable factors of the technological process which make an impact on the used fire alarm units, which is similar to impact by the controlled fire factors, can exceed the threshold values.

EFFECT: increased reliability of fire detection by the automatic fire alarm units in the conditions where the adverse factors of the technological process make an impact on the used fire alarm units, which is similar to impact by the controlled fire factors, and can trigger a fire alarm in the absence of fire, and the fire alarm function implementation.
