3.0 Introduction
The PROIWT Communication Interface will provide the user with a method to interface an Innovative
Wireless Technologies intrinsically safe communication system with the NIOSH-approved BioPak 240R
respirator. The system consists of a MSHA-approved interface component that will position a microphone
into the speech outlet of a Biomarine PRO PP facemask. A lapel-mounted speaker will connect to the
mask via either a 12” or 18” coax cable and the speaker will also interface to a two-way radio via a coiled
cable. The radio and remainder of the communication system is supplied directly by Innovative Wireless
Technologies.
Installation of the PROIWT interface to the PRO PP mask will not interfere with the operation of the
standard PRO PP voice emitter. Speech can be heard both through the microphone and through the
mask emitter simultaneously.
Warning:
It is strongly recommended to install the PROIWT Interface to the PRO PP mask and
leave it in place at all times. Multiple installations and removals will tend to strip the
screw holes in the mask speech channel body. Should one or more the screw holes
become stripped; a replacement speech channel body can be ordered from Biomarine
under part number B2-06-6002-93-0.
