George Risk Industries 8572 Andover 10 kΩ Resistor Pack

George Risk Industries 8572 supplies two 10 kΩ resistors for Andover physical-security applications. The pack addresses installations that need the specified resistance at more than one supervised input circuit. Rather than treating resistance as an incidental wiring detail, use the matched value called for by the receiving controller or input module so the circuit can be evaluated as intended. In an alarm or access-control enclosure, resistor placement affects how an input interprets normal, open, and fault conditions. Apply each resistor only at the location and with the circuit topology prescribed for the connected Andover equipment. Two supplied resistors support work on two applicable circuits, or provide a second unit where the installation documentation requires the same 10 kΩ value. The component pack belongs with low-voltage physical-security wiring and panel termination work. Selection turns on the required resistance and platform compatibility, not on the sensor type alone. This pack is specifically designated for Andover use and supplies 10 kΩ resistance in a quantity of two. It does not substitute for a controller, contact, cable, or termination enclosure; it is the passive resistance component used alongside those items. Verify the intended circuit point before installation, particularly when inputs use different supervision arrangements within the same system.
