This operating manual describes how to use the Searchpoint Optima Plus infrared point gas detector.
The Searchpoint Optima Plus infrared point gas detector is designed for use in potentially hazardous areas, detecting hydrocarbon gases and vapours by dual‑wavelength infrared absorption. The manual provides guidance on safe installation, electrical connections, and commissioning procedures.
Safety warnings emphasize compliance with regional codes such as BS5345 and NFPA 70, and state that the unit must not be operated in atmospheres containing more than 21% oxygen. Maintenance should be performed only by qualified personnel, and a planned maintenance programme is recommended.
