FIELD: engineering of fire alarms, namely - combined fire alarms, possible use for detecting fire by increase of environmental temperature and/or appearance of smoke in place of alarm mounting.
SUBSTANCE: problem is solved by mutual decrease of thresholds during detection of two fire factors, meaning joint consideration of these factors during taking of decision about forming of alarm notification.
EFFECT: increased reliability of fire detection at early development stage.
