Document No. D251-00-601-IS Issue 1 20-09-2022 Sheet 7 of 7
IECEx Approval
The IS-mC1 Combined Sounder / Beacon has also been
approved to the IECEx scheme.
The installation requirements for IS-mC1 combined sounder /
beacon approved to the IECEx scheme are the same as the
installation requirements for IS-mC1 combined sounder /
beacon approved to the ATEX directive.
Certificate No.
IECEx SIR 06.0045X
Marking:
Ex ia IIC T4 Ga (Ta = -40ºC to +60ºC)
Standards:
IEC 60079-0:2017
IEC 60079-11:2011
IEC 60079-26:2014-10
CONDITIONS OF CERTIFICATION (as stated on the IECEx
Certificate of Conformity IECEx SIR 06.0045X)
The equipment has an ingress protection rating of
IP65. However, if it has been supplied without a
cable entry device, then the user shall ensure that
the devices that are fitted will provide an ingress
protection that is appropriate to the environment in
which it is installed i.e. IP20 on better. If only one of
the two cable entries are used, then the unused
entry ‘knockout’ shall be left intact or fitted with a
blanking device that ensues ingress protection
appropriate to the environment in which it is installed
i.e. IP20 or better.
The total capacitance connected to Sounder
Terminals + w.r.t. Terminals - (i.e. the capacitance
of the cable plus any other capacitance) shall not
exceed 83nF.
The enclosure is non-conducting and may generate
an ignition-capable level of electrostatic charges
under certain extreme conditions. The user should
ensure that the equipment is not installed in a
location where it may be subjected to external
conditions that might cause a build-up of
electrostatic charges on non-conducting surfaces,
additionally, cleaning of the equipment should be
done only with a damp cloth.
The equipment shall only be supplied via Sounder
Te w.r.t. Sounder Terminal - from a barrier
having a maximum open circuit voltage Uo that is <
28V and a maximum short circuit current Io that is <
93mA, where Io is resistively limited.
If not already fitted optional internal wiring
connections between Sounder Terminals + / - and
Beacon Terminals + / - may be fitted by the user.
The wiring used for such connections shall have a
minimum radial thickness of insulation of 0.5mm.
The IS-mC1 combined sounder / beacon is marked with the
certification requirements for the ATEX and IECEx and
approvals.
