Optical smoke detector MKII-OP
MKII-OP optical smoke detectors use 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).
- Designed in compliance with EN54
- Lockable to base to prevent unauthorised removal
