Otis Instruments Omniguard Model 860 UV/IR flame detector is designed to detect unwanted fires and output alarm information. The Model 860 senses ultraviolet radiation and infrared radiation in the appropriate wavelengths for early fire detection. Utilizes the patented Omniguard Fire Event Analysis Algorithm to provide superior false alarm immunity. Otis Instrument flame detectors have an automatic self-test function to monitor the detector's ability to sense fires and report a fault condition when impaired.
Notes: Swivel mount (20856) included. Other configurations available - Please call 1-800-333-3331 for more information.
