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, versions
of the BA354E are available with FM and cFM
intrinsic safety and nonincendive approval, project
identifications 3041487 and 3041487C. Copies of
the Certificates of Compliance are available from
the BEKA associates sales office and
www.beka.co.uk
The FM and cFM Approved Rate Totaliser is
identical to the ATEX & IECEx certified versions
except the three M20 x 1,5 tapped cable entries
are replaced by three plain unthreaded 22.25mm
diameter entries. Approved hubs and glands are
listed in note 7 of Intrinsically Safe Control Drawing
CI300-72 and note 5 of Nonincendive Control
Drawing CI300-73. The certification label on the
FM and cFM Approved version also includes ATEX
and IECEx gas certification information so that the
Rate Totaliser may also be used in systems
covered by either authority.
A3.1 Intrinsic safety approval
The BA354E Rate Totaliser is 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 BA354E has a T5 rating at ambient
temperatures up to +70ºC and may be used with
the following gases and dusts:
Intrinsic Safety

Class I Group A & B
Group C
Group D
Class II Group E, F & G
Class III
Zone 0, 1 or 2
Class 1 Group IIC
Group IIB

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.
A3.2 Nonincendive approval
The BA354E Rate Totaliser is also approved to
nonincendive standard FM Class 3611 allowing
installation in Division 2 hazardous (classified)
locations without the need for Zener barriers or

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
