Engines running in an enclosed car park or loading dock produce carbon monoxide, which gives no warning. Detectors at breathing height switch the extract fans on demand and report over cellular, so the air is managed by what is in it rather than by a timer.
Queues at exits and vehicles idling at docks raise CO fastest where people stand.
Nobody notices CO until they feel it.
Ventilation run by measured CO runs when it is needed and not all day.
| Target gas | Carbon monoxide (CO) |
|---|---|
| Selectable ranges | 0-500 / 2000 / 5000 / 10000 ppm |
| Mounting height | Breathing height, about 1.5 m: the gas mixes into the room |
| Where the detectors go | At breathing height along driving lanes; near ramps, exits and queuing areas; at loading docks where vehicles idle |
| Outputs | Two alarm relays, 4-20 mA and RS485 Modbus RTU, all at once |
| Reporting | RS485 into a Genesis controller, then over cellular to alerts and a record |
The detector relays switch the fan, close the valve or sound the beacon locally, with no network involved.
The same reading goes over cellular to the people on the alert list, wherever they are, with acknowledgement recorded.
Concentration, time and duration are kept on a record that exports to Excel, for the incident review and the next inspection.
Yes. Each detector has two relays that switch locally on its own set points, for example a low stage and a high stage of ventilation.
The NIOSH Pocket Guide lists a recommended exposure limit of TWA 35 ppm (40 mg/m³) C 200 ppm (229 mg/m³), an OSHA permissible exposure limit of TWA 50 ppm (55 mg/m³) and an IDLH of 1200 ppm. These are United States values; set alarm points against the rules that apply at your site.
Which gases, how many points, where they sit and what they report into. We come back with the cells, the ranges and the positions.
