Page 2: System Description
Alarm and Fault as normal. 3. Detector Positioning. It is important that the Fireray FD2705R/FD2710R Detector is positioned correctly to minimise the detection time. Experiments have shown that smoke from a fire does not rise directly upwards, but fans out or mushrooms due to air currents and heat layering effects. - Page 3 9 metres either side of the beam, but only for the beam positioned in the apex. All other calculations remain the same. Limit to when a Fireray must be positioned in roof apex Angle of Pitch Limit...

Page 4: Installation
Due to the principle of the detector i.e. reflective, the prism(s) must NOT be mounted on glass or a polished reflective surface. Mount the Prism(s) on a solid structure, 90º to the beam path, between 5 to 50 metres (Fireray FD2705R), and 50 to100 metres (Fireray FD2710R) directly opposite the Detector. -

Using the mode switch (See fig. 4) select ‘Operating Mode’ (Switch will be in the down position). On exiting ‘Alignment mode’ the Detector will perform an internal calibration check. If this fails, which would be due to bad alignment or either electrical or optical noise, the power level will try to compensate. -
