Monitoring system energizing detectors of room closures against extension of smoke, or fire

摘要

The system comprises at least one first detector (11) of fire characteristic, supplied from a voltage source (5) and consisting of a detector member (3) and a switch (4) which disconnects current supply of a detector (6) in case of alarm. The first detector also contains a communication element (13) and an evaluation and monitoring circuit and is coupled to second detectors (12), each with a detector member, an inner energy suply (15), and second communication element (16), transmitting information, e.g. alarm and identification data.
