Zeta Alarm Systems MKII-HF optical smoke detector

The Zeta Alarm Systems MKII-HF conventional detector uses a pulsing IR LED & photodiode to detect IR scatter caused by smoke entering the chamber. The detector is particularly suitable for detecting optically dense smoke, involving materials such as soft furnishings, PVC, plastic, foam and all similar materials which produce small visible particles (0.5 to 10μm). The detector is designed to meet EN54 requirement.
