This contact is designed in such a way that magnetic interference from surrounding metals is reduced, allowing it to be used in steel framed doors. The barrel of this contact holds 4 sloped crush ribs – allowing it to easily slide into a 20mm diameter recess, locking at the contact plate. 6 core wiring allows this contact to be used with both, either or none of the included resistors. The 2k2/4k7 resistors provided are suitable for use with a variety of Castle, Menvier, Pyronix, Scantronic and Texecom Premier panels, as well as any others that use the 2k2/4k7 configuration. Magnetic Interference Detection allows it to meet the standards required for Security Grade 3.
