George Risk Industries R1-B-2.2K 2.2K Ohm Resistor

Product Description

The GEORGE RISK INDUSTRIES INC. R1-B-2.2K is a 2.2K ohm resistor used in security and alarm system wiring applications. Resistors of this type are installed in series or end-of-line configurations to supervise circuit continuity and enable zone detection by a control panel. Licensed alarm installers and low-voltage security technicians are the primary trades working with this component. It is a small, passive electrical component that regulates current flow within a supervised loop circuit.

This resistor is commonly used in hardwired security alarm systems where end-of-line (EOL) resistor supervision is required. It is suited for residential and light commercial installations where a control panel monitors door contacts, window contacts, motion detectors, or other hardwired zone devices. The 2.2K ohm value is a standard resistance used by a number of control panel manufacturers for supervised zone wiring.

Key Features

• 2.2K ohm resistance value for supervised alarm circuit wiring
• Compatible with end-of-line resistor supervision configurations
• Compact form factor for easy integration into contact housings or junction boxes
• Sold individually per unit of measure

Compatibility

Designed for use in hardwired security alarm and access control systems requiring end-of-line resistor supervision. Verify the required resistance value with your specific control panel documentation before installation.

Installation Notes

Installation should be performed by a licensed low-voltage or alarm systems technician in accordance with local codes and manufacturer panel documentation. De-energize the alarm circuit and disarm the control panel before adding or replacing resistors in a supervised zone. Resistors are typically installed at the last device in a zone loop, inside the device housing or at the terminal block. Confirm the required EOL resistance value matches the panel zone programming before commissioning the circuit.
