Development of Electronic Circuits for Advanced High Temperature Fire Detectors.

摘要

This program was directed toward developing electronic circuits for advanced high temperature infrared and ultraviolet fire detectors which had been developed by the laboratory. A circuit which is applicable to any gas discharge type of UV sensor performed satisfactorily; however, the high temperature UV sensor did not perform reliably above 600F. A circuit for a 750F infrared fire detector was developed and performed satisfactorily. The circuit uses the flicker phenomenon of fuel type fires to distinguish the fire from background sources. This circuit is applicable to any similar solid state infrared sensor.
