Stationary gas warning systems in garages, tunnels and loading zones are the  crucial monitoring instrument  of a ventilation system. It regulates the air quality in enclosed spaces and decides when to start the ventilation.

Reliable application is regulated throughout Europe in the  EN 50545 standard. EN 50545 - the central standard for gas monitoring in garages and tunnels - requires extensive prerequisites for gas alarm systems. The gases CO, NO2 and LPG to be monitored by means of sensor technology are defined in the standard.

In addition to the type of warning,  SIL monitoring  is also required to EN 50271, which is referenced in EN 50545.
