1 Safety Information
1.1 Correct Use
The MSA G1 SCBA wireless accessories uses Bluetooth technologies for audio communications
and/or data sharing. Every SCBA is equipped with a Bluetooth Module to enable a wireless connection
between the SCBA and an MSA approved compatible device.
These user instructions will provide detailed steps in how to set up and use these Bluetooth wireless tech-
nology features. Below are a few key definitions to help throughout the user instructions.
Key Definitions:
Pairing - The state in which two Bluetooth devices are set up to connect to each other by storing each
device's Bluetooth address. Paired but unconnected devices will not transmit audio and/or data.
Connection - The action of two paired devices communicating and sharing data from one to another. Audio
and/or data will only transmit between the devices after a successful connection.
CAUTION!
Bluetooth operation is dependent upon signal availability of the wireless service(s) necessary to maintain
the communication link. Loss of wireless signal will disrupt the audio or data link from the SCBA to the Blue-
tooth compatible device and result in loss of audio communication and/or data sharing. Do not attempt to
reestablish wireless services in a hazardous atmosphere.
If loss of signal occurs in a hazardous or contaminated area, restart the Bluetooth device and use in
stand alone mode per manufacturer’s instructions.
Once you have returned to a safe atmosphere, restart both the Bluetooth device and SCBA to reestab-
lish the wireless signal.
It is imperative that the user instructions be read and observed when using the device. In particular, the
safety instructions, as well as the information for the use and operation of the device, must be carefully read
and observed. Furthermore, the national regulations applicable in the user's country must be taken into
account for a safe use.
Alternative use, or use outside this specification will be considered as non-compliance. This also applies
especially to unauthorized alterations to the device and to commissioning work that has not been carried
out by MSA or authorized persons.
1.2 Liability Information
MSA accepts no liability in cases where the device has been used inappropriately or not as intended. The
selection and use of the device are the exclusive responsibility of the individual operator.

Pairing a Motorola APX portable radio that uses a Remote Speaker Microphone (RSM)
The pairing sequence for Motorola APX portable radios that utilize a RSM is the same as described above.
Please refer to the pairing sequence for either a single or two display radio to pair the portable radio to the
MSA G1 SCBA.
3.4 Usage (Connecting)
This section gives instruction about how to properly use or connect the SCBA and radio after pairing has
been established.
Connecting the SCBA to the Portable Radio
Prior to using the G1 SCBA with a Motorola radio, ensure that the SCBA and radio are paired to one another.
If necessary, clear the pairing history and re-pair both devices per the instructions displayed in section 5.
(1) Turn on the Motorola radio. It is recommended to turn on the Motorola radio first when starting up both
the SCBA and radio.
(2) After the radio is powered on, turn on the G1 SCBA via pressurization. Once the SCBA is fully powered
on, the SCBA will connect and immediately disconnect from the Motorola radio.
NOTE: As long as the user is not breathing through the regulator, the radio will function independently of
the G1, and all portable radio communications will originate and pass through the radio only.
Once breathing begins on the regulator, the radio and SCBA will connect automatically within 20 seconds.
When the connection is complete, all SCBA long range voice communication will go from the SCBA through
the portable radio.
NOTE: If the regulator is shut off, the radio and SCBA will automatically disconnect, and all portable radio
communication will go back through the radio only.
NOTE: After the pairing tag is successfully read, a Bluetooth enabled G1 SCBA will search for a pairing
partner for 8 minutes. If a pair has not been made after 8 minutes, the G1 will stop looking for a pairing
partner. If the 8 minute time out is exceeded, the pairing process should be started over.
NOTE: After a successful pairing, if the regulator is shut off, the G1 SCBA will not remain connected to the
APX radios. As long as the G1 regulator is shut off, the APX radio is available for normal, non-Bluetooth
use. The G1 SCBA will automatically re-connect to the Motorola radio the next time an end user breathes
on the G1 regulator.
The G1 SCBA and Motorola single display radio are now paired and ready for use.

4.1 Enabling Bluetooth Functionality with MSA Gas Detectors
(1) Power on the MSA gas detector per the device instructions.
(2) Wait for the sensor warm-up phase to complete.
Due to the device calibration and start up times, MSA recommends powering on the gas detector
device first. Allow the gas detector to completely startup before moving on the next step.
The device is ready for pairing once the Blue LED begins to blink quickly.
(3) Power on the SCBA.
IMPORTANT! The remaining pairing steps detailed below must be completed within 8-10 minutes of
the G1 SCBA being powered on. If the pairing process is not initiated within 8-10 minutes of the
G1 SCBA being powered on, the steps below must be repeated.
(4) Place the G1 into RFID mode:
a) Access the RFID tag reader on the G1 SCBA by pressing and holding both of the 2 GREEN control
module buttons until the RFID icon displays on the control module
(5) Place the RFID chip of the Gas Detector onto the RFID
reader of the SCBA.
a) The Gas Detector RFID chip location differs depending
on which model is in use.
b) The Altair 5X RFID tag is located under the MSA logo
on the front of the device.
A green RFID icon will display on the G1 control module
along with an audible double beep to confirm that the
RFID tag was read successfully.
(6) Accept the pairing request when it is displayed on the gas
detector.

(7) The gas detector is now successfully paired to the G1.
A successful Bluetooth wireless connection will result in
a slow blinking BLUE LED on the Altair 5X and a solid
green Bluetooth icon on the G1 control module
secondary screen
Once an MSA gas detector and a G1 SCBA have been
paired successfully the pairing will be maintained across
power on/off cycles for both devices indefinitely.
If the pairing process is unsuccessful, there will be no
slow blinking LED on the gas detector and the steps
above will need to be repeated.

Bluetooth Device Pairing Removal
G1 SCBA
US
5 Bluetooth Device Pairing Removal
There are three different ways to remove the pairing connection between an MSA G1 SCBA and a corre-
sponding Bluetooth device (Radio or Gas Detector). Pairing should only be removed when a user wants to
ensure the existing G1 SCBA and Bluetooth device do not connect during the next startup or if the G1 SCBA
needs to be paired with another Bluetooth device.
The three options for pairing removal are:
(1) Removing the battery on the G1 SCBA. This action will clear ALL Bluetooth pairing history stored within
the G1 SCBA.
(2) Pairing a new or different radio or gas detector by repeating the pairing processes detailed in sections
3 and 4. This will remove the previous Bluetooth device pairing information from the G1 SCBA and the
G1 will now only work with the most recently paired Bluetooth device.
(3) Creating a Reset Bonding tag in the A2 application and scanning the SCBA with the RFID tag.
5.1 Maintaining Pairing Information
The G1 SCBA factory default setting is for all pairing information to be cleared from the SCBA every time
the battery is removed from the SCBA. This is done so that if the SCBA will routinely be paired with multiple
radios or gas detectors that it is easy to clear pre-existing pairing data.
The G1 SCBA can be configured so that pairing information is retained across battery removals. This is
most appropriate for use cases where the SCBA will be paired to a single radio or gas detector for a long
period. The procedure for configuring the SCBA to retain pairing information is as follows:
(1) Access the A2 Software application and verify that the latest version of SW is being used.
(2) Select G1 Tags from the main screen.
(3) Choose G1 Configuration from the left side menu.
(4) Click button labeled Add G1 Configuration.
(5) Select Bluetooth Setting from the sub menu.
(6) Select Bluetooth Pairing Save from the sub menu.
(7) Place a blank RFID tag onto the RFID reader/writer.
It is highly recommended to clear the pairing of the radio and the SCBA at the same
time. Do not clear the pairing information from only the SCBA and not the radio. Refer
to section 5.1 for detailed instructions on removing the radio pairing information.
There is no reason to ever clear the pairing from an MSA Gas detector itself. Removing
the pairing from the G1 is all that is needed when removing a Gas Detector - SCBA
pairing.
The third option is needed if the G1 SCBA has been customized to maintain Bluetooth
pairings across battery removals. This customized setting has to be done through the
A2 application and requires the creation of a Bluetooth Pairing Save tag (refer to
section 5.1). The factory default setting is for pairing information to clear when the
battery is removed so this option is only necessary if the SCBA has been specifically
customized to maintain the pairing during battery removal.

with Bluetooth. Only
the MSA Altair 4XR
and Altair 5X with
Bluetooth are
compatible with the
G1 SCBA.
Utilize an MSA Altair 4XR or
Altair 5X with Bluetooth gas
detector.

Can I pair my G1 SCBA with a non-Motorola Bluetooth radio?
• No. MSA only approves the use of the SCBA with Motorola APX version radios.
What happens to the Bluetooth connection when I take off my regulator and the radio remains on?
• The G1 will automatically disconnect the BT connection when the regulator on the SCBA is turned off,
and the radio will resort back to normal functionality. The G1 will also automatically reconnect the BT
connection to the radio the next time the regulator is in use.
Why does the large push to talk button on the RSM not work?
• This is the expected behavior of the Motorola RSM when in Bluetooth mode and connected to an SCBA.
The smaller push-to-talk button must be used to transmit audio directly through the G1 to the radio. If the
larger push-to-talk button is used, audio will still transmit, but it will not go directly through the SCBA and
will not take advantage of the G1 audio filtering.
