The Fireray 5000 System is an auto-aligning, self-correcting infrared reflective beam smoke detector. Up to 2 detector heads can report to a single ground level controller. In addition, each system controller houses two pairs of fire and trouble relays, one per detector. Once the detector head is installed, using the easy-fit mounting system an integral LASER can be activated. This allows the reflective prism to be located quickly and with confidence.
