Combined optical smoke and rate of rise heat detector 8060 provides early warning of fire condition upon reaching a smoke concentration threshold and rate of rise of the temperature. Fire detector type 8060 combines the advantages of Optical-smoke detector type 8030 and Rate of rise heat detector 8020, and is an attractive option due to decreased expenses for supply and installation. The fire detector is microprocessor controlled and operates a sophisticated algorithm for self-compensation of contamination. The fire detector complies with the requirements of EN 54/5 and EN 54/7.
