This instruction sheet describes installations which conform
to:
EN60079-14:2008/IEC60079-14:2007 Electrical Installation in
Hazardous Areas.
When designing systems for installation outside the UK, the
local Code of Practice should be consulted.
The certification marking is as follows:
1) The certificate number has an 'X' suffix, which
indicates that the certificate contains one or more
special conditions for safe use. Those installing or

Sealing of Enclosure & Mechanism: 'O' Ring
If the equipment is likely to come into contact with
aggressive substances, then it is the responsibility of
the user to take suitable precautions that prevent it
from being adversely affected, thus ensuring that the
type of protection is not compromised.
"Aggressive substances" - e.g. acidic liquids or
gases that may attack metals, or solvents that may
affect polymeric materials.
"Suitable precautions" - e.g. regular checks as part
of routine inspections or establishing from the
material's data sheet that it is resistant to specific
chemicals.
2.2 Zones, Gas Groups and Temperature Classification
The IS-D105 sounder has been certified Ex ia IIC T4 Ga.
