P-3612PE hydrogen versus PE KAYO-3612
P-3612PE is the PE-family fixed hydrogen gas detector, whereas PE KAYO-3612 is a separate impact-detection product line. Select the correct feature set before attempting to reuse cable wiring, outputs or maintenance procedures. Hydrogen-specific calibration, sensor placement and the controller’s interpretation of 0–100% LEL are essential for safety integration; a catalytic element is not proof of a complete alarm system. The displayed Prosense ATEX/IECEx certificate identifiers are family references and must be reconciled with the exact P-3612PE model suffix, cable entry and actual installation zone.
