Car Park CO Monitoring
Sensor calibration and ventilation controls for enclosed car parks.
The Silent Killer in Enclosed Spaces
Carbon monoxide from vehicle exhausts accumulates in enclosed car parks without adequate ventilation, reaching toxic concentrations that kill within minutes. CO is colorless and odorless—occupants experience no warning before unconsciousness. 50ppm causes headaches and nausea, 400ppm induces unconsciousness within hours, 1600ppm kills within one hour. Enclosed car parks require continuous CO monitoring triggering mechanical ventilation preventing dangerous accumulation.
CO sensors measure ambient concentrations activating ventilation fans when thresholds are exceeded. Sensors drift over time reading lower than actual CO levels, failing to trigger ventilation at dangerous concentrations. Annual calibration verifies sensor accuracy against known CO concentrations. BMS integration ensures ventilation responds to sensor readings. Fire override systems transition ventilation from CO control to smoke extraction during fire events maintaining safe evacuation conditions.
System Maintenance & Integration
CO Sensor Accuracy Tests & BMS Integration
Annual calibration using certified test gases verifies sensors measure CO concentrations accurately. Sensor drift testing identifies units requiring replacement. BMS integration testing confirms ventilation systems respond correctly to sensor alarms. Control logic verification ensures fan speeds increase proportionally with rising CO levels.
Ventilation Override Function
Manual override enables facilities staff to activate ventilation independent of sensor readings during maintenance or incident response. Time-based overrides provide ventilation during peak usage periods regardless of sensor readings. Override testing verifies systems respond to manual commands ensuring operational flexibility.
Fire Event Integration
During fire events, car park ventilation transitions to smoke extraction mode maintaining extract operation even when CO sensors indicate low levels. Fire signal integration testing verifies fire alarm signals override normal CO-controlled operation. Failure to integrate systems allows smoke accumulation during evacuations creating life-threatening conditions.
