Safety Standards (cont.)
Anyone intending to use a radio in a hazardous area is advised to become
familiar with the subject of intrinsic safety and with Section 70 of the National Fire
Code, which is commonly referred to as Article 500 of the National Electric Code.
Use of anything but factory supplied components may affect the approval and
safety of the radio. Likewise, it is advised that servicing should be performed only
by qualified personnel who adhere to the following Factory Mutual Research
Corporation (FMRC) required warning:
Modification of FMRC-Approved intrinsically safe radios will
negate Factory Mutual Research Corporation Approval.
Certain JT 1000 radios and batteries have been declared intrinsically safe by
FMRC of Norwood, Massachusetts, for use in hazardous atmospheres. FM
Approved radios are identified by attached certification labels and by matching
green dots found on the bottom of radios and batteries. The intrinsically safe
rating by Factory Mutual Research Corporation states that electrical equipment is
incapable of releasing sufficient electrical or thermal energy, under normal or
abnormal operating conditions, to cause ignition of a specific hazardous
atmosphere. This means the JT 1000 radio has been thoroughly tested by
Factory Mutual Research Corporation and carries its certification for operation in
the hazardous atmospheres designated on the radio label. Radios must ship
from the Motorola factory with the hazardous atmosphere capability and
cannot be modified in the field. Failure to use the radio with the approved battery
will negate the approval. JT 1000 radios that are approved by Factory Mutual
Research Corporation can be used in those applications requiring reliable two way
hand-held radios in the listed specific hazardous atmospheres. Motorola approved
equipment and accessories, along with competitive equipment approvals, are listed
in the yearly approval guide published by Factory Mutual Research Corporation. This
guide can be ordered from the following address:
