Title:
FIRE ALARM APPARATUS
Document Type and Number:
WIPO Patent Application WO/1990/004241
Kind Code:
A1
Abstract:
This invention provides a fire alarm apparatus which detects a plurality of detection information by a plurality of fire detection means for detecting physical quantities on the basis of a fire or by a plurality of detection means including at least one fire detection means and environment detection means associated with the fire detection means, which subjects the plurality of detection information to integral signal processing and which is suitable for obtaining at least one fire information for fire supervision. To this end, the fire alarm apparatus comprises a table for storing a specific set of detection information and a set of fire information to be obtained when a specific set of detection information is given; a signal processing network constituted so that a suitable weight is given to each inputted detection information in accordance with the degree of contribution to said each fire information and each fire information is calculated on the basis of the detection information thus weighed; and adjustment means for adjusting the weight so that each fire information calculated when a specific set of the detection information is given to the signal processing network is approximated to the set of the fire information inside the table described above.
