Installation
Please read the guides on the installation, use and maintenance of flammable gas
and oxygen detectors (standard EN/IEC 60079-29-2) and toxic gas detectors
(standard EN 45544-4).
2.1 Regulations and conditions of use
• Where applicable, the installation should meet all the regulations currently in force for
installations in explosive atmospheres, in particular standards IEC/EN 60079-14 and
IEC/EN 60079-17 (current editions).
• Generally speaking, the ambient temperatures, supply voltages and power outputs that
are mentioned in this document relate to explosion safety. They do not relate to the
detector's operating temperatures.
• The equipment is authorized for use in ATEX zones 2 and 22 at ambient temperatures
between -20°C and +55°C.
• The sensor in the transmitter should always be in contact with ambient air. Therefore:
- Do not cover the detector
- Do not paint the detector
- Avoid dust
• The OLCT 10N may be used only with the TELEDYNE OLDHAM SIMTRONICS MX 16
or MX32v2 or MX 43 or MX 256 measurement and alarm controller.
Only catalytic versions are certified to use in ATEX II 3GD zone

2.2 Location of the detector
Depending on the density of the gas to be detected or the application, the detector shall be
positioned at ground level, or on the ceiling at the same height as the airflow, or near air
extraction ducts. Heavy gases may be detected at the ground level, while light gases will be found
at ceiling height.
