Knight Grade 3, 4 Terminal White Surface Contact with Resistors

The YEND74 is a 4 terminal white surface contact complete with selectable EOL/Alarm resistors. Resistor selection is provided by shunt placement. A sprung tactile microswitch provides tamper protection, detecting removal of the lid. Magnetic interference detection provides Grade 3 functionality. This unit can be downgraded to Grade 2 via shunt placement. EOL Resistors: 1k, 2k2, 4k1, 4k7, 5k6. Alm Resistors: 1k, 2k2, 4k1, 4k7, 5k6, 6k8. These resistors cover the majority of leading panel manufacturers including Honeywell, Texecom, HKC, Risco etc. Both contact and magnet are 78x24x20mm with rounded edges for a smoother look. The contact can be wired without the integral resistors (Traditional / 4-Wire) if necessary. YEND74 is suitable for shared zone installation with 2+ contacts. Along with fitting screws, this contact also comes with 2x 3mm spacer shims to assist with installations that are not entirely level. Additional shims can be purchased in a 5 pack - use part code SPA-LS. YEND74 operates at a gap of approximately 30mm. Also available in brown - use part code YEND74B. Also available in Grade 2 - use part code D75MULTI. - Operating gap: ~30mm - Microswitch tamper protection - Integral resistors (shunt selection) - Shared zone ready - PCB with wire clamping terminal blocks - Supplied with fitting screws and shims
