4.1
Switching on
(1)
Open compressed air cylinder.
(2)
If pressure > 15 bar, SingleLine SCOUT starts up.
a) Electronic component check:
All LEDs are flashing once, an acoustic signal sounds and the gauge LEDs light up green. The
device is ready for use.
If only red LEDs light up and no acoustic signal sounds, do not use the device. There is an
electronical damage.
b) Optional: High pressure tightness test:
–
Press manual alarm button within first 30 seconds after self test was confirmed.
Allow 8 to 12 seconds for stabilisation before closing the cylinder valve.
–
Close cylinder valve and double click on the alarm button.
The self test starts measuring the pressure drop within 60 seconds; red and yellow LEDs flash
while the test is running.
If the pressure drop is < 10 bar within 60 seconds, the device tightness is confirmed by an
acoustic sound and green gauge LEDs flashing.
–
Release air slowly using the lung governed demand valve until warning whistle sounds up.
–
Close the lung governed demand valve and reopen cylinder valve to use the SCBA.
NOTE:
Pressure drop must not be > 10 bar / 60 seconds. If the pressure drop is > 10 bar within 60
seconds, the test is stopped with an acoustic sound and red LEDs flashing. The device is not tight. Do
NOT use the device.
(3)
If pressure < 15 bar, SingleLine SCOUT does not start up.
If only red LEDs light up and no acoustic signal sounds, the pressure level or battery capacity
might be to low.
4.2
Switching off
Switching off the SingleLine SCOUT is only possible in the pressure-free status. The device is considered to
be pressure-free if the measured pressure is less than 15 bar.
(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 sounds between 60 and 0 bar.
(2)
Push the alarm button twice.
The pressure alarm switches off.
(3)
Push the alarm button twice.
An acoustic signal sounds.
The device switches off.
4.3
Pressure Status Message
While operating, the device makes an acoustic sound at the following pressure thresholds:
