System Design
Engineers familiar with codes of practice for
hazardous area systems should only
undertake the design of an flameproof fire
detection system. In Europe the standard is
EN 60079-0 (formally EN 50014), Electrical
apparatus for potentially explosive
atmospheres – General requirements.
The fire detector performance is the same as
the standard none flameproof counterparts.
Performance information given in standard
product guides is therefore applicable to the
flameproof range.
The Baseefa certification of the flameproof
device enclosure covers their characteristics
as components of a flameproof system. This
indicates that the flame detectors can be
used with a margin of safety in such
systems.
Service & Repairs
1. Frequent inspection should be made. A schedule for the maintenance check should be
determined by the environment and frequency of use but should be regular enough to
ensure the detector continues to operate in the designed manner. It is recommended that
it should be at least once a year.
2.
External surfaces of the enclosure should be periodically cleaned to ensure dust deposits
are not allowed to accumulate.
3. Check flamepath/threads on enclosure body and lid for signs of corrosion. If badly pitted,
replace component.
4. All components that are replaced must be in accordance with the manufactures
specification. Failure to use such components may invalidate the certication/approval on
the enclosure and may make the enclosure dangerous.
5. After inspection and maintenance have been carried out, items 3 & 4 of the installation
instructions should be adhered to when resealing the enclosure.
Servicing of the fire protection system should be carried out as recommended by the local regulation
in force.
