1 Safety Regulations
1.1 Correct Use
The M1 Control Module, in this manual also referred to as device, is a personal monitoring unit that
monitors the proper functioning of a respiratory protective device. It displays the current operating data
of the respiratory protective device and signals danger conditions (visually and acoustically).
It is imperative that this operating manual 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 care-
fully read and observed. Furthermore, the national regulations applicable in the user's country must be
taken into account for a safe use.
WARNING!
This product is supporting life and health. Inappropriate use, maintenance or servicing may affect the
function of the device and thereby seriously compromise the user's life.
Before use, the product operability must be verified. The product must not be used if the function test
is unsuccessful, it is damaged, a competent servicing/maintenance has not been made, genuine MSA
spare parts have not been used.
Alternative use, or use outside this specification will be considered as non-compliance. This also
applies especially to unauthorised alterations to the product and to commissioning work that has not
been carried out by MSA or authorised 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.
Product liability claims, warranties and guarantees made by MSA with respect to the device are voided,
if it is not used, serviced or maintained in accordance with the instructions in this manual.

Description
GB
2 Description
Fig. 1 Overview M1 Control Module
The M1 Control Module (see Fig. 1) is connected at the end of the high pressure gauge line of an appli-
cable MSA SCBA.
The device monitors the proper functioning of the respiratory protective device and signals danger
conditions (visually and acoustically). The digital display shows the current operating data of the respi-
ratory protective device, especially the pressure level which is also visible via the mechanical gauge.
In addition, the device automatically triggers an alarm if the apparatus user is not moving and provides
the opportunity for manual alarm triggering.
Green, yellow and red LEDs - buddy lights - mounted on both sides of the device indicate the pressure
state of the device. In the event of pressure alarm, motionless alarm or a manual alarm activation via
button, bright red buddy lights flash highly visible.
The device is equipped with an internal data memory for saving the operational data for more than 30
sessions with up to 20 min working time.
An RFID reader is located in the head of the device to read M1 TAGs for personalizing the device.

3 Installation
Installations can only be done by certified MSA technicians outside of hazardous areas.
4Use
4.1 Before Use
Before using the device, it is recommended to perform a short check to test for any leakage in the
system.
(1) Open compressed air cylinder.
(2) When device is started, close compressed air cylinder.
(3) Double press the alarm button.
4.2 Switching on
(1) Open compressed air cylinder.
If pressure < 30 bar, the device does not start up.
If pressure ≥30 bar, the device starts up.
4.3 Switching off/into Standby
The device is considered to be “off” when in Standby mode and monitoring the pressure level exclu-
sively. It is only possible to switch into Standby mode in the pressure-free status which is a measured
pressure below 15 bar.
To switch into Standby mode:
(1) Close the valve(s) of the compressed air cylinder(s) and vent the compressed air breathing
apparatus via the lung governed demand valve (see operating manual for compressed air
breathing apparatus).
An acoustic signal occurs between 60 and 0 bar.
(2) Push one of the mode buttons twice.
The pressure alarm turns off.
(3) Push one of the mode buttons twice.
An acoustic signal occurs.
The device turns into Standby mode.
Completely switching off the device is only possible by removing the battery.
The display turns white, shows the actual pressure and a progress bar.
If a green tick is displayed and the device turns on, the device can be used.
If a red cross is displayed, usage of the device is not recommended. Return the device to
a technical expert for check.
Electronic component check is performed:
All LEDs are flashing once, an acoustic signal occurs and the display lights up. The device is
ready for use.
If red LEDs light up and low battery symbol is displayed, the battery capacity might be to
low, see section 4.9 "Battery Charging".

4.4 Operating Modes
Service Mode
To activate the Service Mode:
(1) Press one of the green buttons longer than 5 sec.
The Service mode is activated.
(2) Use the green mode buttons to switch between the separate menu and submenu options.
For more information, see MSA A2 Software.
Mode Description
Standby Mode The display is turned off and the device only monitors the pressure level. To leave
this mode, pressurize the device.
Reading Mode This mode is used before device start-up to read in information stored on a TAG,
see section 4.11 "Personalization".
Scout Mode
The device is turned on and monitors the proper functioning of the SCBA.
The LEDs indicate the battery life and the buddy lights indicate the pressure level
in the compressed air cylinder.
By pressing one of the green mode buttons, the user can switch between the
pressure level and the remaining time display.
Service Mode This mode can be used in combination with MSA A2 Software to change device
settings and read out log memory.

4.5 Pressure Status Message
While operating in Scout mode, the device makes an acoustic sound at the following pressure thresh-
olds:
• 1st pressure threshold – Single beep (standard setting: 200 bar)
• 2nd pressure threshold – Double beep (standard setting: 100 bar)
• Low pressure threshold – Double beep (60 bar) repeated until confirmed, see section 4.8
"Confirming Alarms"
These thresholds, except from the low pressure warning, can be changed using the MSA A2 Software
in combination with a Bluetooth enabled PC.
See MSA A2 Software for more details.
Cylinder Pressure Display
The cylinder pressure is displayed via the integrated mechanical gauge and additionally displayed on
the integrated display. Current pressure can be read from both, the gauge or display.
The following display thresholds represent the standard setting and, excluding the < 60 bar threshold,
can be changed using MSA A2 Software in combination with a Bluetooth enabled PC.
See MSA A2 Software for more details.
Pressure level in compressed air cylinder Display Buddy lights
> 100 bar green
between 100 bar and > 60 bar yellow
