George Risk Industries Inc. 8572 Resistor Pack 10K Ohm

Product Description

The GEORGE RISK INDUSTRIES INC. 8572 is a resistor pack containing two 10K ohm resistors, designed for use in security and access control wiring applications. This component integrates into supervised alarm circuits where end-of-line or in-line resistor termination is required to maintain circuit integrity. It is typically installed by alarm technicians and low-voltage security contractors as part of a complete door or window contact installation. The 8572 is sold as a single unit and is identified for Andover-compatible configurations.

This resistor pack is used in supervised security circuit installations, particularly where zone supervision with a 10K ohm resistance value is specified by the panel manufacturer or system designer. It is suited for residential and light commercial alarm panel wiring. The Andover designation indicates compatibility with Andover-style supervised contact applications. Installers incorporate these resistors at the contact or in the wiring loop to allow the panel to distinguish between an open, closed, or faulted zone state.

Key Features

• Includes two 10K ohm resistors in a single pack for supervised circuit termination
• Andover-compatible resistor configuration for alarm and access control systems
• Sold as an individual unit for precise inventory and job-site control
• Compact form factor suitable for installation within contact housings or junction points
• Appropriate for low-voltage supervised zone wiring in residential and commercial security systems

Compatibility

Designed for use in Andover-compatible supervised alarm circuit applications requiring 10K ohm end-of-line or in-line resistor termination. Specific panel compatibility should be verified against the panel manufacturer's zone supervision requirements prior to installation.

Installation Notes

Installation should be performed by a licensed low-voltage or alarm system technician in accordance with local codes and NEC Article 725 for Class 2 and Class 3 remote-control and signaling circuits. De-energize the alarm panel zone before making any wiring connections. Resistors should be placed at the designated supervision point in the circuit as specified by the panel or system documentation. Avoid over-bending resistor leads, which can affect resistance values and circuit reliability.
