Operation
4. Select the gas detector on the smartphone:
a. Short name of the gas detector in the Android/iOS Bluetooth
®
menu.
b. Part number and serial number in optional Dräger app.
A 6-digit number is displayed on the smartphone and on the gas detector.
5. Check that the numeric code on both devices match and, if they match, confirm
on both devices. The devices must be coupled within 20 s otherwise the numeric
code will become invalid.
✓ Coupling of the devices is complete.
Once a connection has been successfully established, it is saved and the two
devices are automatically connected in the future (adjustable via the CC-Vision
PC software).
If the connection is lost, the gas detector automatically tries to establish a new
connection.
A connection to the Dräger Connectivity Hub is established automatically if the
gas detector is registered to the same tenant as the Dräger Connectivity Hub.
For more information, see the Dräger Connectivity Hub instructions for use.
A short tone sounds to indicate that a connection is being established.
A double tone indicates that the connection has been terminated.
4.6 During operation
WARNING
Danger to life and/or risk of explosion!
The following alarms indicate a danger to life and/or risk of explosion:
– A2 alarm
– STEL or TWA alarm
– Device/channel error
► Immediately leave the hazard area.
WARNING
Incorrect measured values!
Only for diffusion mode: If water seals the gas inlets on the gas detector (e.g. in
heavy rain or if the gas detector is submerged in water), incorrect measured values
may be returned.
► With the display facing downward, shake the gas detector to remove the water.
WARNING
Incorrect measured values!
A different reading may be shown if the gas detector experiences a considerable
impact or a significant vibration.
► When using a CatEx or IR sensor (depending on the gas detector type), a
calibration of zero-point and sensitivity must be carried out after an impact load
that results in a fresh air display not equal to zero.
