Description

The 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. Utilizes the patented Omniguard Fire Event Algorithm for superior false alarm immunity and quick detection of hydrocarbon fueled fires.

Features

  • Patented Fire Event Analysis (FEA) Algorithm for Superior False Alarm Immunity
  • Operating Temperature: -40°F to 185°F (-40°C to 85°C)
  • User-Selectable Sensitivities
  • Long Range Detection
  • Diagnostic Ter-Test No External Test Source Required)
  • Self-Contained, Explosion-Proof Enclosure
  • Sensitivity gurable Relays and
  • State-of-the-Art Microprocessor Control
  • Wide Field View of 90°
  • FM, CSA, IECE and ATEX Approved
  • 5-Year Warranty
