Generac Part 6665 QT Remote Monitor Adapter Kit
The Generac 6665 is a proprietary harness adapter kit specifically designed to enable the use of Generac's older, basic, local wireless remote monitor (Model 6664, which is a simple indicator light device) on large, liquid-cooled standby generators. This 6665 adapter kit provides the correct length and proprietary connectors needed to bridge the gap between the monitor's transmitter and the liquid-cooled generator's internal control board (specifically the Nexus controller).
Features
Truly Wireless:
- The monitor unit itself is completely wireless and battery-operated, allowing you to place it anywhere in your home.
Convenient Mounting:
- It has a compact, sleek design and features a magnetic back for quick placement on a refrigerator or other metal surface, as well as options for wall or desk mounting.
Extended Range:
- Offers reliable 600-foot line-of-sight communication (and often better penetration through walls compared to older models).
Factory Paired:
- The unit is automatically paired at the factory to its corresponding transmitter unit at the generator, eliminating the need for complex in-field pairing procedures.
The monitor relies on a simple, traffic-light system using LED indicator lights:
🟢 Green LED   Ready:
- Generator is functioning correctly and is ready to start automatically during an outage.
🟡 Yellow LED   Maintenance/Warning:
- Indicates a non-critical alert, such as a scheduled maintenance reminder or a low battery warning. (The generator is generally still ready to run.)
🔴 Red LED   Fault/Alarm:
- Indicates a shutdown alarm or a fault that prevents the generator from running automatically. Requires attention and dealer service.
- Low Battery Alert Â
- The monitor will emit a separate audio alert when its internal battery is low and needs replacement.
