Fire and explosion detection apparatus |
摘要 |
Fire and explosion detection apparatus comprises an ultra violet detector providing a first output signal in response to receipt of ultra violet radiation and an infra red detector providing a second output signal in response to receipt of infra red radiation. A logical AND circuit, in response to simultaneously occurring first and second output signals, provides a third output signal indicative of simultaneous receipt of ultra violet and infra red radiation.
