Appendix 3
FM Approval for use in the USA and
cFM Approval for use in Canada
A3.0 Factory Mutual Approval
For installations in the USA and Canada, both models
have FM and cFM intrinsic safety and nonincendive
gas approval (not dust), project identifications
3041487 and 3041487C. Copies of the Certificates
of Compliance are available from the BEKA
associates sales office and www.beka.co.uk.
A3.1 Intrinsic safety approval
The indicators are approved to FM Class 3610
intrinsic safety standard for use in Division 1 and 2
hazardous (classified) locations. Installations must
comply with BEKA associates Control Drawing
CI300-72, which is attached to this appendix,
ANSI/ISA RP12.06.01 ‘Installation of Intrinsically Safe
Systems for Hazardous (Classified) Locations’ and
with the National Electrical Code ANSI/NFPA70.
Installations in Canada must comply with the
Canadian Electrical Code C22.2
The front of all both models have IP66 protection. To
obtain an IP66 seal between the indicator and the
panel in which it is mounted, the installation must
comply with note 11 of Control Drawing CI300-72.
Both models have a T5 rating at ambient
temperatures up to +70ºC and may be used with the
following gases:
Intrinsic Safety
Division 1 or 2
Class I Group A & B
Group C
Group D
Zone 0, 1 or 2
Class 1 Group IIC
Group IIB
Group IIA
The FM and cFM entity parameters are similar to the
ATEX and IECEx parameters and the systems shown
in section 4 of this manual may therefore also be used
for FM and cFM installations.
The FM and cFM Control Drawing CI300-72 for
intrinsically safe applications which is contained in this
appendix, specifies that when correctly installed a
BA307E-SS or a BA327E-SS will not invalidate the
certification of an AEx e, AEx p or AEx n panel
enclosure. Providing that the local code of practice is
followed, this allows the indicators to be installed as
shown in sections 4.3.1 and 4.3.2 of this manual.
A3.2 Nonincendive approval
Both models are FM Class 3611 nonincendive
approved allowing installation in Division 2
hazardous (classified) locations without the need
for Zener barriers or galvanic isolators. US
installations must comply with the BEKA
associates Control Drawing CI300-73, which is
attached to this appendix, and with the National
Electrical Code ANSI/NFPA70.
Canadian nonincendive installations must comply
with the Canadian Electrical Code C22.2 and with
BEKA associates Control Drawing CI300-73, which
is attached to this appendix.
The front of all the models have IP66 protection.
To obtain an IP66 seal between the indicator and
the panel in which it is mounted, the installation
must comply with note 13 of Control Drawing
CI300-73.
All the models have a T5 rating at ambient
temperatures up to +70ºC and may be used with
the following gases:
Nonincendive
Division 2
Class I Group A & B
Group C
Group D
Zone 2
Class I Group IIC
Group IIB
Group IIA
