George Risk Industries 6644-1 Dual 1K Ohm Resistor 1/8W

Product Description

The George Risk Industries 6644-1 is a dual 1K ohm resistor rated at 1/8 watt, designed for use in security and access control wiring circuits. This component provides end-of-line or in-line resistance balancing for supervised alarm loops and contact circuits. It is a single-piece, passive electrical component installed by security system technicians and licensed electricians during panel wiring or sensor termination. The 1/8 watt power rating makes it appropriate for low-current supervisory circuits typical in commercial and residential alarm systems.

This resistor is used in supervised door and window contact circuits where a defined resistance value must be maintained across the loop to allow the alarm panel to distinguish between open, closed, and tamper states. It is well-suited for residential and light commercial security installations where consistent loop resistance is required at the sensor termination point.

Key Features

• Dual 1K ohm resistance value for supervised loop applications
• 1/8 watt power rating appropriate for low-current alarm circuits
• Compact passive component — no external power required
• Sold individually for precise quantity ordering

Compatibility

Designed as an OEM-style accessory for use with supervised security contact circuits requiring end-of-line or in-line resistor termination.

Installation Notes

Installation is typically performed by a licensed security technician or electrician during alarm system wiring or sensor commissioning. De-energize the alarm panel and associated zone circuits before handling or terminating resistor leads. Follow applicable NEC guidelines for low-voltage wiring practices. Do not exceed the rated wattage of the component during installation or testing.
