  • Page 2: System Description

    1. System Description. Fireray 50/100RU Detector comprises a Transmitter and Receiver contained within one enclosure. The Detector installs to the building fabric between 1 and 2 feet from the ceiling. The Transmitter emits an invisible infrared light beam that is reflected via a prism mounted directly opposite and with a clear line of sight.

  • Page 3: Detector Positioning

    3. Detector Positioning. An infrared signal is projected out of the transmitter optics (see Fig 3) to the reflector placed at the opposite end of the detection zone. The signal is reflected back to the receiver where it is analysed for fire and Trouble.

  • Page 4: Installation

    Due to the principle of the detector i.e. reflective, the prism must NOT be mounted on glass or a polished reflective surface. Mount the Prism on a solid structure between 15 to 160 feet (Fireray 50RU), and 160 to 330 feet (Fireray 100RU) directly opposite the Detector.
  • Page 5 5. Prism Targeting Mode. Apply power to the Detector. There is a 5 seconds pre-charge delay after power is applied to allow the internal circuits to stabilise correctly. After this period the RED indicator will flash once to indicate that the model is a 50RU or will flash twice to indicate a 100RU.
  • Page 6 • FLASHING AMBER The Detector is receiving a weak signal and is attempting to increase the infrared power output. • The Detector has optimised the infrared power and receiver gain for the current orientation of the Detector and Prism. This does not mean that the Detector to Prism alignment is at its optimum, i.e.

    6.4. Exiting Alignment Mode. Do not remove the detector from the wall during this action. Using the mode switch (See fig. 4) select Run Mode (Switch will be in the down position). On exiting alignment mode the Detector will perform an internal calibration check, this can take up to 60 seconds.

  • Page 9: Connection And Configuration Settings

    7.2. Trouble Test. Cover the Prism totally with a non-reflective material and confirm that the Detector indicates a Trouble condition after approximately 10 seconds (the amber LED on the Detector will illuminate, and the Trouble relay opening will indicate this). The Trouble condition will automatically reset after a period not greater than 2 seconds when the obstruction is removed.
