Using infrared beams, optical beam detectors are designed to identify smoke over much larger areas than traditional fire detection devices, making them suitable for large indoor spaces. They work by transmitting a beam of invisible infrared light across the building space to be protected. Usually wall-mounted at near-ceiling level, a receiver detects and measures the light and can recognise smoke interference anywhere along the beam path, triggering the alarm signal when the pre-determined threshold is reached. 

The Fireray 5000 is said to detect smoke over distances up to 100 metres. The motorised, reflective, auto aligning infrared system can be installed with up to two detector heads per system and each system controller houses two pairs of fire and fault relays, one per detector.

The China Certification Centre for Fire Products (CCCf) is a fire product qualification institution approved and authorised by the Chinese government. Its business scope covers fire product and fire-related product certification and the drafting of codes, standards and detailed regulations.
