Efficiency from one single source Our optimally coordinated components – all planned, installed and maintained in an instant

The centrepiece of the system is an optoelectronic sensor. The basic configuration is intentionally limited to few components by combining a sensor unit with a warning unit, in order to guarantee a high level of reliability, longevity and simple installation. Based on each specific application, another sensor or signalling unit can be connected to a second room or a second entrance. In addition, ventilators and suction devices can be directly controlled via a switching unit. 

CO2 CONTROL basic package

  • Comprising: warning unit, sensor unit and distributor
  • Description: for monitoring of one or maximum two rooms over a control centre / warning unit. Extendable with additional components, such as signal unit, switching unit or second sensor unit  
  • Areas of application: mainly in the area of dispensing equipment, protection of cold storage cells, CO2 cylinder rooms, kitchenettes with water dispensers, simple industrial applications.


  • Comprising: extended warning unit with floating outputs in the low-voltage range. Redirection of the operational and alarm status to upstream control elements
  • Description: as with the basic package, however, combined with the “external world”
  • Areas of application: CO2 coolant area, packaging industry, CO2 fire extinguishing systems, hotel and system catering, breweries / wine press houses


  • Comprising: extended warning unit with 230V/50 Hz floating outputs, especially complying with requirements for CO2 coolant systems. Linking and confirmation of additional alarm units, one-man initialisation, shared cable for supply and control, additional optical-acoustic warning.
  • Description: as with CO2 CONTROL PA, however outputs with 230V/50 Hz. The AM PLUS variant has an additional strong horn and a large flashlight to attract greater attention.
  • Areas of application: Refrigerating devices at discounters, food retailers, food processing, industrial refrigeration systems
