•HEARING PROTECTION WARNING: This communications product is designed to produce a
specific audio output level at a maximum rated power. Many countries now have regulations defining
the amount of noise that an individual can be subjected to during a normal workday. The duration of
exposure, and the level of ambient noise will affect compliance to these regulations. Compliance is
application dependent, and standards vary. It is the SOLE RESPONSIBILITY of the end user to
determine applicability of and compliance to local hearing protection regulations.

2.0 MSHA Electrical Approval
Innovative Wireless Technologies
1100 Main Street, Lynchburg, VA 24504 USA
Model: PROIWT
Permissible Communication Interface
MSHA Approval No: 23-A120005-0
Tested for intrinsic safety in methane-air mixtures only.
Warnings:
MSHA approved for use with one of the following IWT
communication systems only:
SENTINELTM Wireless Mesh Communication and
Tracking System
The interface can only be connected to the Biomarine
Inc. PRO PP facemask.
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.

4.0 Installation
The PROIWT interface will install into the PRO PP facemask in place the facemask voice emitter front
cover. The speaker portion of the system will clip to the lapel of the user’s shirt or to the harness of the
BioPak 240R respirator. A cable is utilized to connect the facemask interface components to the speaker.
The speaker is provided with a coiled cable attached that will interface with the 2-way radio supplied with
the Innovative Wireless Technologies communication system.
Warning: Do not damage the voice emitter cup of the facemask during PROIWT installation.
The voice emitter, located internal to the mask, cannot be cut, slit, punctured, or
otherwise damaged. A damaged voice emitter will result in a breach of the respirable
air circuit of the BioPak.
1. Using a T20 Torx screwdriver, remove the four front cover screws and reserve for reuse as
depicted below.
2. Inspect the rubber skirt of the mask and verify that it is properly positioned within the groove of the
speech channel body as depicted below. The skirt must be positioned in the groove of the speech
channel body around its entire perimeter.

4. Remove the voice emitter by pushing down on the release tab and pulling straight out.
Warning: Do not damage the voice emitter cup of the facemask during PROIWT installation.
The voice emitter, located internal to the mask, cannot be cut, slit, punctured, or
otherwise damaged. A damaged voice emitter will result in a breach of the respirable
air circuit of the BioPak.

7. Reinstall the nose cup around the perimeter of the voice emitter as depicted below. If the mask is
fitted with a drink tube, make sure the drink tube is properly positioned as depicted.

8. Position the oval-shaped foam piece around the perimeter of the PROIWT microphone as
depicted below.
9. Position the PROIWT interface assembly onto the speech body channel as depicted below. Verify
that the rubber skirt of the mask has not been forced out of the speech channel body groove.
Secure the interface into position using the four Torx screws from step 1. Hand-tighten the screws
evenly and DO NOT OVER-TIGHTEN.
10. Don the facemask and determine which microphone cable is best suited for the user. The
microphone cable will connect the interface assembly to the speaker and is supplied as a 12” or
18” length. The selected length shall not restrict head movement of the user and should be
positioned to minimize the potential for snagging. The cable contains locking connectors on both
ends. To engage the cable simply line up the contactors and press together. To disconnect the
cable, pull back on the outer shell to release.

11. Prior to the using the system, leak test the facepiece to verify proper installation of the interface.
Leak testing can be achieved utilizing the Biomarine PRO PP Field Test Kit, part number B6-02-
5003-43-0.
12. Follow the directions provided for the speaker and radio to ready the communication system for
use.
13. To Install the Speaker and Radio Cable to the 2-Way Radio:
a) Turn the radio off. Installation of the speaker while the radio is powered may cause the radio
to transmit constantly, locking the radio system. If this occurs, turn off power to the radio.
The radio can then be powered on, restoring normal operations.
b) Remove any dust caps or covers from the radio cable connector.
c) Attach the speaker radio cable to the radio connector.
d) Tighten the mounting thumbwheel.
5.0 Communication System Use
Refer to instructions for the Innovative Wireless Technologies SENTINELTM Wireless Mesh
Communication and Tacking System for proper operation of the radio and complete system. The user
should speak in normal tones and not shout. Avoid talking when the mask is bumping or banging into
other objects as the sound waves may be picked up by the microphone and distort speech.
To speak into the facemask microphone, depress and hold the rubber side button of the speaker while
speaking.
To speak through the mask voice emitter just speak normally and the sound will transmit through the slots
in the interface cover.

6.0 Communication System Post Use
At the completion of a mission, follow all instruction provided by Innovative Wireless Technologies to shut
down the Innovative Wireless Technologies SENTINELTM Wireless Mesh Communication and Tacking
System. Remove the microphone cable from the interface and remove the speaker and radio from the
user. The interface should remain installed in the facemask. Cover the connectors of the interface with
the supplied cap to protect. Wash and inspect the facemask as described in the BioPak 240R Benchman
Manual. Be sure that contacts of the interface connector are fully dry prior to reuse.
Warning: Make sure the contactors of the interface connector are fully dry before re-using the
facemask.
Warning: When not in use, keep the contactors of the interface protected by covering with the
included cap.
Warning: Do not allow the facemask with the interface installed to soak in disinfectant or remain
submerged in liquid for extended periods. Ten minutes is all that is required to fully
disinfect the mask.
Warning: There are no servable parts within the interface component, cables, or speaker. Do
not disassemble the components or the validity of the MSHA intrinsic safety approval
will be voided.
The front grill of the speaker can be removed for cleaning if needed. To remove the front grill, grip the
speaker in one hand, use the palm of the other hand to press down on grill and turn ¼ turn to the left.
Grill will lift out of housing. Grill can be removed to wipe away dust, dirt, moisture, etc. from inside the
cavity to ensure optimum performance. An optional debris screen, part number B2-06-6002-88-0, may be
located under the front grill and is used in those environments with intense conditions. The debris screen
can be washed with warm soapy water and replaced, when completely dry, back into the unit.
Removable Front Grill of Speaker
To remove the front grill of the speaker, reference Illustrated Parts List, grip speaker in one hand, use
palm of other hand to press down on grill and turn ¼-turn to the left. Grill will lift out of housing. Grill can
be removed to wipe away dust, dirt, moisture, etc. from inside cavity to ensure optimum performance. An
optional debris screen, B2-06-6002-88-0, may be located under the front grill for use in environments with
intense conditions. The debris screen can be washed with warm soapy water and replaced, when
completely dry, back into the speaker.
