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.

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).
