The Fireray 5000 System is an auto-aligning, selfcorrecting infrared beam smoke detector. Up to 2 detector heads can report to a single ground level controller. Once the detector head is installed, using the easyft mounting system an integral LASER can be activated. This allows the refective prism to be located quickly and with confdence. The Auto-Align function ensures proper alignment and maximum signal during the beam installation. AutoOptimise automatically steers and maintains the beam in the optimum position for reliable performance. The signal generated in the transmitter element and refected by the prism back to the receiver element is analyzed for the presence of smoke. The internal microprocessor determines an alarm condition when a predetermined level obscuration is reached. The system is designed to be mounted so the beam will project between 1ft. (0.31m) and 2ft. (0.61m) below and parallel to the ceiling. Lateral detection may be up to 30ft. (9.144m) on either side of the beam, providing a maximum total coverage area of up to 19,800 square feet (60ft. x 330ft. or 18.29m x 100m).
