Gas detection controller for car park or tunnel CPS

Regarding gas detection, professionals in the sector must follow the technical instruction of 3 March 1975 relating to the ventilation and monitoring of the atmosphere in car parks (car park regulations or enclosed spaces where vehicles are present). The latter recommends limit values for carbon monoxide and nitrogen monoxide concentrations.

To better prevent the risks linked to exhaust gases (CO, NO, NO2, LPG, or H2) presence, most car parks are provided with air extractors which are very expensive in terms of energy. The CPS gas detection controller for car park offers a safety aspect with a permanent analysis of the gas concentration and an economic characteristic with optimum control of the ventilation and smoke extraction systems. This monitoring reduces costs by improving ventilation efficiency.

In addition to the CPS10 gas sensors, many additional modules are available, such as 4 or 8 relay cards (for automatic controls), logic input cards (for firefighter commands) and analog output cards for measurement copying or dimmer controls.

The existing major harmful gases in car parks and tunnels are carbon monoxide (CO) and nitrogen oxides (nitric oxide and nitrogen dioxide). Other gases are also found, in lower concentrations, such as LPG (butane, propane, CNG) and, more recently, hydrogen (H2) emitted during the charging of electric vehicles.
