SPECIFICATION DATA PointWatch® Infrared Hydrocarbon Gas Detector Model PIR9400 A P PL ICAT ION S 5 The PointWatch® detector is a diffusion-based point-type infrared gas detector approved to provide continuous monitoring of methane gas concentration in the range of 0 to 100% LFL. The detector provides a 4-20 mA output signal, WARRANTY corresponding to the detected gas concentration. The detector has Division and Zone explosion-proof ratings and is suitable for use in indoor and outdoor applications. Y ear PointWatch is ideally suited for use in harsh environments and where the cost of required maintenance for conventional catalytic detectors is prohibitive. The PointWatch IR detector will perform reliably in the presence of silicone and other catalytic poisoning agents and can also operate in oxygen free environments or where high background gas levels are present. There are no known poisons that affect this technology. The PointWatch detector is globally certified for use in Class 1, Divisions 1 and 2, and Zones 1 and 2 hazardous areas. It is also approved as a stand alone gas detector, and complies with global approvals when connected to a stand-alone approved controller for life safety. The approved Det-Tronics controllers are the FlexVu® UD10, Infiniti® U9500, R8471, and Eagle Quantum Premier® (EQP). FE ATU R E S A N D B E N E FITS • Compliance to ANSI/ISA 12.13.01-2000 performance standard. • Requires no routine calibration to ensure proper operation. • Fail-safe operation. • Continuous self-test automatically indicates a fault or fouled optics condition. • Unique multi-layered filtering system protects optics from dirt and water ingress. • Internal heating system minimizes condensation, allowing reliable operation through temperature extremes. • There are no known poisons, e.g. silicones or hydrides, that compromise the integrity of the measurement. • Performs well in the presence of high concentrations or constant background levels of hydrocarbons, and in oxygen depleted atmospheres. • Standard 4–20 mA output (current source). • Compact, lightweight, explosion-proof housing is designed for duty in harsh environments. • Standard 0 to 100% LFL detection range. 4.1 ©Detector Electronics Corporation 2011 10/11 90-1074
