Document No. IS 4501 Issue E 27-11-09
Sheet 6 of 6
The IS-A105N Sounder has also been approved to the IECEx
scheme.
The installation requirements for IS-A105N sounders
approved to the IECEx scheme are the same as the
installation requirements for IS-A105N sounders approved to
the ATEX directive.
Certificate No.
IECEx SIR 04.0038X
Marking:
Ex ia IIC T4 Ga (Ta = -40ºC to +60ºC)
Standards:
IEC 60079-0:2004
Edition 4
IEC 60079-11:2006
Edition 5
IEC 60079-26:2006
Edition 2
CONDITIONS OF CERTIFICATION (as stated on the IECEx
Certificate of Conformity IECEx SIR 04.0038X)
1. The equipment shall only be supplied via Terminals
+ w.r.t. Terminals - from a certified barrier having a
maximum open circuit voltage Uo that is less than or
equal to 28 V and a maximum short circuit current Io
that is less than or equal to 93 mA, where Io is
resistively limited.
2. The total capacitance connected to ter wrt –
(i.e. the capacitance of the cable plus any other
capacitance) shall not exceed 83nF.
3. The equipment has an ingress protection rating of
IP66; however, if it has been supplied without a
cable entry device, then the user shall ensure that
the device that is fitted will provide an ingress
protection that is appropriate to the environment in
which it is installed i.e. IP20 or better.
4. The enclosure is non-conducting and may generate
an ignition-capable level of electrosatic 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 IS-A105N Sounder has also been FM Listed.
Marking: IS Class I, Zone 0, AEx ia IIC T4

See the Control Drawings D 4528 Sheets 1 and 2 for
installation details and entity parameters.
The IS-A105N sounders are marked with the certification
requirements for the ATEX, IECEx and FM approvals.
