  • Page 10: General Description

    UV/IR detectors which are subject to the aforementioned interferences. The F120 flame detector monitors for specific radiation emitted by a fire through the use of 3 sensors - one UV (ultraviolet) sensor and two IR (infrared) sensors. The UV sensor provides the shortest response time in detecting radiation from a fire.

  • Page 11: User Customizable Modes

    This provides a rapid visual check of detector operation and indicates the unit is in operation. The Model F120 Flame Detector responds to a flame with a variety of criteria and time delay settings. A multiposition selector switch sets the detector for the most appropriate mode for the exact conditions at your particular installation.
  • Page 12 Model F120 UV/IR Flame Detector Alarm and Delayed Alarm The Model F120’s standard configuration requires at least two of its three sensors to be activated to signal an alarm. When flame radiation is initially detected, the Alarm outputs, both relay contact and current loop, are instantly activated. A red LED alarm light behind the viewing window in the detector is also activated.
