APPENDIX 1
FM approval for use in the USA and
cFM Approval for use in Canada
A1.0 Factory Mutual Approval
For installations in the USA and Canada the
BA448CF-P has FM and cFM intrinsic safety and
nonincendive
approvals,
project
identification
3027031 and 3027031C. Copies of the
Certificates of Compliance are available from
BEKA
associates
sales
office
and
www.beka.co.uk.
A1.1 Intrinsic safey approval
The BA448CF-P is approved to FM Class 3610
intrinsic safety standard for use in hazardous
(classified) locations. Installations must comply
with BEKA associates Control Drawing CI410-12,
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.
Canadian installations must comply with the
Canadian Electrical Code C22.2 and with BEKA
associates Control Drawing CI410-12 which is
attached to this Appendix.
The BA448CF-P has a T4 rating at ambient
temperatures up to +70
o
C 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 identical to
the ATEX parameters and, like the ATEX
certification, confirm that the BA448CF-P complies
with the FISCO Field Device requirements
specified in IEC60079-27. The intrinsically safe
system shown in Fig 1 of this manual may
therefore be used for installations in the USA and
Canada, providing the fieldbus power supply,
terminators, Zener barriers and galvanic isolators
are FM Approved for US installations and cFM or
CSA Approved for Canadian installations. All
installations must comply with BEKA associates
Control Drawing CI410-12.
FM and cFM Approval also allows the BA448CF-P
to be connected to non-FISCO systems using the
entity concept – see section 4.2 of this manual.
A1.2 Nonincendive approval
The BA448CF-P is also Class 3611 nonincendive
approved by Factory Mutual allowing it to be
installed 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 CI410-
13, 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 CI410-13 which
is attached to this Appendix.
The FM and cFM Nonincendive Approvals also
allow the BA448CF-P fieldbus indicator to be
connected to any appropriately certified FNICO
compliant fieldbus segment.
The BA448CF-P has a T4 rating at ambient
temperatures up to +70
o
C 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
