can optionally be fitted with a protective guard to protect it against external damage. Two versions are available: in widths of 30 mm and 80 mm.
When installing the protective guard, please ensure that the indicator light on the sensor unit remains visible.
Mount the protective guard with 2 wall dowels over the

3.1
Initial commissioning
System initialisation
Once the complete gas detection system has been installed, the system must be initialised using the
warning unit
. For the
CO2 CONTROL AM / AM PLUS
versions, see the additional notes in the
CO2 CONTROL AM / AM PLUS installation sheet.
1. If the system is to be supplied with power from the mains plug, before inserting the mains plug, the
ALARM OFF
button on the
warning unit
must be pressed
until the buzzer sounds. Then, release the button. Upon a successful start of initialisation, you will hear a short beep and ticking from the
warning unit
.
The system will then initialise by itself. The process ends with 4 short signal sounds and the green power lights on the system components will light. After this,
each device must be checked to ensure that all of their green power lights are lit. If this is not the case, the procedure described above must be repeated.
2. If the system is to be connected directly via the distributor (230 V / 50 Hz) to the power supply, the fuse for the corresponding circuit must be switched off
and switched on again with the
ALARM OFF
button pressed until the buzzer sounds. Then, release the button. The initialisation process will then continue in the
same way as in 1. above. For the AM and AM PLUS versions, see the notes on the
CO2 CONTROL AM / AM PLUS installation sheet.
Once initialisation is complete, check all of the connected components to ensure that the
green operating lights are lit!
In the event of a faulty power light, check the system once again and repeat the
initialisation process.
When initialisation fails, the system will switch to alarm mode after approx. 2 minutes.
