A gas-fired boiler room has a fuel supply, burners and hot surfaces in one room. Methane rises, so detectors at the ceiling read in %LEL and close the gas valve on their own relay long before a flammable mixture forms, then report the event over cellular.
Pipework, valves and burners share the room with hot surfaces.
A leak rises and collects under the ceiling.
Boiler rooms run without staff, so a leak is found by detection or not at all.
| Target gas | Methane (CH4) |
|---|---|
| Selectable ranges | 0-10 / 0-50 / 0-100 %VOL·%LEL |
| Mounting height | High, 0.3 to 0.6 m below the ceiling: the gas is lighter than air |
| Where the detectors go | High on the wall above the gas train; near the gas meter and regulator; close to the ceiling, away from extract airflow |
| 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.
For leak detection, %LEL, so the alarm trips long before a flammable mixture forms. The %VOL ranges are for process and biogas measurement.
Which gases, how many points, where they sit and what they report into. We come back with the cells, the ranges and the positions.
