All electronics are PCB mounted, with wire-clamping terminal blocks for easy wiring. This contact can be wired in series, allowing 2+ contacts to share a zone and function as a single unit.\u003c\/p\u003e\n\u003cp\u003eYEND74 features integral EOL resistors suitable for mainstream panels in the following configurations, selected by shunt links on the PCB: 1k\/1k\u003c\/p\u003e\n\u003cp\u003e2k2\/2k2\u003c\/p\u003e\n\u003cp\u003e2k2\/4k7\u003c\/p\u003e\n\u003cp\u003e2k2\/6k8\u003c\/p\u003e\n\u003cp\u003e4k1\/4k1 (Guardall 8k2)\u003c\/p\u003e\n\u003cp\u003e4k7\/4k7\u003c\/p\u003e\n\u003cp\u003e4k7\/6k8\u003c\/p\u003e\n\u003cp\u003e5k6\/5k6\u003c\/p\u003e\n\u003cp\u003eA no-resistor\/dry configuration is also selectable for 4-wire installations where resistors are not required. The tamper is a sprung microswitch, detecting removal of the contact lid. A second tamper reed detects and responds to magnetic interference, meeting the requirements for Grade 3.\u003c\/p\u003e\n\u003cp\u003eThis reed may optionally be bypassed by shunt, reducing the product to Grade 2 level.
