George Risk Industries Inc. R1-W-1K 1K Ohm In-case Resistor

Product Description

The GEORGE RISK INDUSTRIES INC. R1-W-1K is a 1,000 ohm (1K ohm) in-case resistor designed for use in security and alarm system wiring applications. This resistor is housed in a compact white casing that allows it to be installed cleanly within door, window, or perimeter contact assemblies. It is used to provide end-of-line (EOL) resistance in supervised alarm loops, ensuring that the control panel can detect open or short circuit conditions on the line. Installation is typically performed by security system technicians and low-voltage alarm installers.

This resistor is suited for residential and light commercial security installations where supervised contact loops are required. The white casing blends with standard white door and window frames, making it a clean fit for surface-mounted or in-frame contact installations. It is sold individually as a single unit, making it easy to stock and use as needed during new installations or service calls on existing alarm systems.

Key Features

• 1K ohm (1,000 ohm) resistance value for standard end-of-line loop supervision
• White in-case housing integrates cleanly with white contact hardware
• Compact form factor fits within standard security contact assemblies
• Sold as a single unit for flexible stocking and field use

Compatibility

Designed as an OEM-style accessory for use with in-case security contact assemblies requiring end-of-line resistor supervision. Confirm loop resistance requirements with the specific alarm control panel before installation.

Installation Notes

Installation should be performed by a licensed low-voltage technician familiar with supervised alarm loop wiring practices. Power down or disarm the alarm control panel before servicing any contact or loop wiring to avoid false alarms or panel faults. Follow local low-voltage wiring codes and the control panel manufacturer guidelines for correct EOL resistor placement within the loop.
