Otis Instruments Omniguard Model 760 Aluminum Multi-Spectrum Infrared Flame Detector, Auto Self Test, Latching

Otis Instruments Omniguard Model 760 multi-spectrum infrared flame detector is designed to detect unwanted fires and output alarm information. The Model 760 senses infrared radiation in five discreet infrared wavelengths for early fire detection for maximum protection of people, machinery, and facilities. Utilizes the patented Omniguard Fire Event Algorithm for superior false alarm immunity and quick detection of hydrocarbon fueled fires. 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. The self test feature also eliminates the need for any external test fixtures.

Notes: Swivel mount (20856) included. Other configurations available - Please call 1-800-333-3331 for more information.
