Abstract
An integral testing system for testing OFDs is provided. The OFD may comprise a body, a detector, and an infrared source. The detector and the infrared source may be housed with the body. The infrared source may be configured to generate emissions having one or more infrared wavelengths that are detectable by the detector. The infrared source may be configured to produce infrared emissions to simulate flaming fire.
Claims16
An optical flame detector comprising:
- a body;
- a first infrared source housed within the body and configured to generate a first emission having a first wavelength;
- a second infrared source housed within the body and configured to generate a second emission having a second wavelength that is different than the first wavelength, the first emission and the second emission being generated in less than one hundred milliseconds and in response to receiving a request to perform a self-test;
- a first window coupled to the body and configured to filter and reflect the first emission from the first infrared source and the second emission from the second infrared source;
- a second window coupled to the body and configured to filter and reflect the first emission from the first infrared source and the second emission from the second infrared source;
- a first detector housed within the body and configured to monitor an environment through the first window and to receive the first emission from the first infrared source reflected by the first window and to receive the second emission from the second infrared source reflected by the first window;
- and
- a second detector housed within the body and configured to monitor the environment through the window and to receive the first emission from the first infrared source reflected by the second window and to receive the second emission from the second infrared source reflected by the second window.
