• Gas welding requires a system inhibit, since the gas torch is an actual fire.
• Arc welding rods can contain organic binder materials in the flux that burn during the
welding operation and are detectable by the device.
• Welding rods with clay binders do not burn and should not be detected. However, a system
inhibit is always recommended, since the material being welded may be contaminated with
organic substances (paint, oil, etc.) that will burn and may be of the size that should be
detected.
2.2 Preparations for Installation
The installation must comply with local regulations and standards applicable to flame detectors (e.g.,
NFPA 72) and all local and common engineering practices. It is recommended to consult with a safety
engineer.
The detectors can be installed with the use of general-purpose common tools and equipment.
Prior to installation:
• Verify the appropriate purchase order.
•
Record the part and serial numbers of the detectors and the installation date and log.
•
Visually inspect the detector prior to installation to make sure it is intact.
•
Make sure that you have all the components and tools required to complete the
detector installation readily available before beginning installation. In cases where you
cannot complete the installation in a single session, secure and seal the detectors and
conduits before leaving the site.
• Use color-coded conductors or suitable wire markings or labels for the wiring. You may
use 12 to 20 AWG (2.5
𝑚𝑚𝑚𝑚
2
to 0.35
𝑚𝑚𝑚𝑚
2
) wires for the site wiring. The selection of wire
gauge should be based on the number of detectors used on the same line and the
distance from the control unit, in compliance with specifications.
•
Use wire rated for a temperature of at least 111°C, which is 5°C above the rated service
temperature.
