Appendix 1
FM & cFM Approval for use in USA &
Canada.
A1.0 Factory Mutual Approval
For installations in the USA and Canada, the
BA307C, BA308C and accessories have been
approved intrinsically safe and nonincendive by FM
Approvals, project identification 4B3A7.AX-1 and
3032632. Copies of the Certificates of Compliance
are available from the BEKA associates sales
office and from the BEKA web site
www.beka.co.uk.
A1.1 Intrinsic safey approval
The BA307C and BA308C are approved to the FM
Class 3610 intrinsic safety standard and Canadian
Standard C22.2. Installations must comply with
BEKA associates Control Drawing CI300-22, 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 Canadian
Standard C22.2.
The BA307C and BA308C have a T4 rating at
ambient temperatures between –20
o
C and +60
o
C
and may be used in the following divisions with the
following gases:
Intrinsic Safety
Division 1 or 2
Class I Group A & B
Group C
Group D
The FM entity parameters are similar to the ATEX
parameters. The intrinsically safe circuits shown in
this manual may therefore be used for installations
in the USA, providing the Zener barriers and
galvanic isolators are FM Approved and comply
with BEKA associates Control Drawing CI300-22.
For Canadian installations Zener barriers and
galvanic isolators must be cFM or CSA Approved.
A1.2 Nonincendive approval
The BA307C and BA308C have been approved to
the Class 3611 nonincendive standard by Factory
Mutual allowing them to be installed in Division 2
Classified Areas without the need for Zener
barriers or galvanic isolators. Installations must
comply with the National Electrical Code
ANSI/NFPA70.
The BA307C and BA308C have a T4 rating at
ambient temperatures between -20
o
C and +60
o
C
and may be used with the following gases:
Nonincendive
Division 2
Class I Group A & B
Group C
Group D
