Det-Tronics PIR9400 PointWatch Infrared Hydrocarbon Gas Detector - Manual (Page 3)

1 95-8440 9.3
Caution
Be sure to read and understand the entire
instruction manual before installing or operating
the gas detection system. This product is intended
to provide early warning of the presence of a
flammable or explosive gas mixture. Proper device
installation, operation, and maintenance is required
to ensure safe and effective operation. If this
equipment is used in a manner not specified in
this manual, safety protection may be impaired.
APPLICATION
The PointWatch TM Infrared Gas Detector Model PIR 9400
is a diffusion-based point-type infrared gas detector. The
PointWatch Detector is 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, corresponding to the detected gas concentration.
It has Division and Zone explosion-proof ratings and is
suitable for use in indoor and outdoor applications.
The PointWatch Detector Model PIR 9400 is ideally suited
for use in harsh environments and where the cost of
required maintenance for conventional catalytic detectors
is prohibitive. It 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 Zone 1 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 ®
UD 10 , Infiniti ® U 9500 , R 8471 , and Eagle Quantum
Premier ® (EQP).
FEATURES
• 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.
