pairing mechanism) between the process unit and the corresponding unit will be performed and the process unit will be tested with seven additional corresponding units, which had not been paired. One process unit shall be chosen randomly and will be either tested against eight different corresponding units, alternatively the means of matching (e.g. enrol and calibration mechanism for pairing) for each detector. corresponding unit or interference test unit).Р”Р‡or grade 4 detectors purely based on magnetic fields, the manufacturer shall supply a minimum of eight differs of coded pairs or similar means (e.g. The pure interference test magnet shall be applied at any selected area or point directly to each accessible surface of the process unit, while no other magnetic fields shall have influence (e.g. In case of purely magnetic field based products, a further interference test shall be performed. Pass/Fail criteria: Signals or messages shall be generated in accordance with Table 2 in the presence of the interference test unit or the detector shall continue to work normally if the make and break distances do not exceed twice the specified values. In case the connecting field is purely magnetic, both polarisation directions shall be tested parallel and perpendicular on each chosen point. Monitor the outputs of the process unit, and measure the make and break distances in accordance with 4.3.1. If due to the size of the surface it is possible to position the interference test unit on more than one position, then the test should be repeated at several randomly chosen points. The interference test unit shall be applied on all exposed surfaces reference Annex F. For lock state contacts mounted flush in ferromagnetic material directly, the test shall be undertaken using 2 steel mounting plates based on the material defined in Annex E, having dimensions of (200 x 200 x 1,6) mm. For lock state contacts mounted on ferromagnetic material directly, the test shall be undertaken with the process unit placed on a steel mounting plate based on the material defined in Annex E, having dimensions of (600 x 600 x 1,6) mm.

The interference test unit shall be applied onto all exposed and accessible housing surfaces when mounted normally.Р”Р‡or detectors designed for installation in a ferromagnetic environment, the tests shall be performed in such an environment following the installation instructions and using the installation material (if required) by the manufacturer. The test environment/installation shall allow reproducible adding and removal of the corresponding unit without any changes to the original installation distance, to simulate the locking and, for combined products, the opening and closing of the monitored object. If a prohibited area is described by the manufacturer, the distance of this area will be added to the previously calculated separation distance.

The process unit and the corresponding unit shall be installed according to the manufacturerРІР‚в„ўs description with a separation distance calculated as 50 % of the specified make distance on the РЎС“-axis.

This test shall be performed for grade 3 and grade 4 products only. Resistance to magnetic field interference
