Archived and current model-name crosswalk
Prosense’s 2020 PE-KAYO specification table explicitly identifies the petrol vapour model code P-3212PEK; the current English PE Kayo catalog lists PE KAYO-3212 for the same gas description. These are source-level naming records, not proof of unrestricted revision or accessory interchangeability. Resolve the delivered order code, gas calibration, label and certificate issue with Prosense before replacement or procurement.
Petrol-vapour detection versus a defined fuel gas
The historical P-3212PEK is listed in Prosense’s archived catalog for petrol vapour and motion/impact monitoring. Petrol vapour is a variable hydrocarbon mixture, so the applied calibration and LEL alarm interpretation must follow Prosense’s named model and the actual installation, not a propane or methane setting chosen because the unit looks identical. At a filling station, potential vapour release paths, ventilation and fuel-handling equipment influence detector positioning. The three-axis impact function, gas 4–20 mA reading and any Modbus communications are separate alarm-system signals and must be commissioned accordingly. Historical and current product names do not independently prove certificate scope for a substituted unit.
