GUIDELINES FOR TAPE REPAIR:
The MMC sonic Trimode tape is verified as Intrinsically Safe by SIRA and BASEEFA (British
Approvals Service for Electrical Equipment in flammable atmospheres) in the United Kingdom.
In order to maintain the validity of the approval, tape units can be repaired only by MMC or our
authorized guaranteed repair offices approved by SIRA, BV, DNV, BASEEFA, CSA. We cannot offer
that approval; it must be given by the approval agency.
To maintain our agreement with the above-mentioned approval agencies and yet accommodate our
customers as much as possible, we have developed three sets of modules, which can be purchased as
units and installed by the owners of the tapes. However, we must know the serial number of the tapes
involved in order to maintain our records properly.
The Modules Developed are:
COMPLETE HUB ASSEMBLY

battery) faceplate, nameplate, gasket, and battery connection cap (approval agency and temperature
