The motion sensor only detects movements or vibrations.
The motion sensor does not detect whether the user is
moving independently. If the user is not moving
independently, but is located on a moving surface, the
distress signal unit may not issue an alarm.
Buddy-light
The buddy-light in the lid ensures that the closed-circuit
breathing apparatus and the user remain visible even in poor
visibility. Team colleagues are notified of warnings and alarms
on this closed-circuit breathing apparatus.
3.2.3 Status indicators
The status of the closed-circuit breathing apparatus is
signalled with LEDs and sounds. The blue and red LEDs of
the Connect ECU and the buddy-light show the same thing.
The states of the closed-circuit breathing apparatus are
signalled as follows:
3.2.4 Accessories
Dräger provides the following accessories for the closed-
circuit breathing apparatus:
– Heat protection
The heat protection can be used at high temperatures in
order to improve the effect of the cooling medium and
increase breathing comfort.
– Grip clamp
The handle can be additionally secured with the grip
clamp in particularly tough operating conditions or high
temperatures.
– Skids
Skids can be attached to the lid. The skids serve as
spacers when the closed-circuit breathing apparatus
needs to be pushed along a surface, and reduce any wear
to the lid.
– Cold protection insulation
Cold protection insulation is available for use in very low
temperatures.
3.3 Intended use
The closed-circuit breathing apparatus supplies the user with
breathing air for approx. 4 hours, thus making it independent
from the oxygen-deficient and polluted ambient air.
3.4 Limitations on use
3.4.1 General information
The closed-circuit breathing apparatus is not intended for use
as a diving apparatus. Brief and/or complete immersion of the
apparatus in water (e.g. when navigating a waterhole in a
mine) will not impair the function of the closed-circuit
breathing apparatus.
If the closed-circuit breathing apparatus has been
completely immersed or the pressure reducer highly
contaminated, the pressure reducer must be thoroughly
cleaned in order to prevent any contamination from reaching
the inside of the pressure reducer.
3.4.2 Measures with temperatures below 0 °C
The use of cooling media is not mandatory. If the closed-
circuit breathing apparatus is to be used at temperatures
below 0 °C, the use of a cooling medium is not recommended.
The following measures must be taken, however:
– Measure A:
The full face mask visor can fog up from the inside and
freeze, restricting vision. To prevent freezing, treat the
visor with the anti-fog solution given in the instructions for
use for the full face mask. Do not use any other agent.
– Measure B:
Store the closed-circuit breathing apparatus at
temperatures of +10 °C to +25 °C to ensure that all parts
are functioning correctly.
– Measure C:
Use the corresponding cold protection insulation.
If the closed-circuit breathing apparatus is used at
temperatures below -6 °C, this may lead to shorter life cycles
(see "Technically possible period of use", page 27).
