GENERAC 6664 Wireless Remote Monitor

The 6664 remote monitor communicates up to 600 feet line of sight from the generator. That is line of sight, so walls, metal siding, and distance around corners cut into it. In a typical house the monitor sits inside on the kitchen refrigerator while the standby unit is out on the pad, which is well inside that range. For a property manager placing one in an office across a courtyard from the generator, measure the straight path, not the walking distance.

No wiring at all. The 6664 is completely wireless and battery powered, so there is no low voltage run to pull and no connection to the transfer switch or generator terminals. You set it where you want status visible. It has a magnetic back for mounting on a refrigerator or any steel surface, which is how most owners place it.

Three status colors: green, yellow, and red, backed by a buzzer that sounds when the generator needs attention. Green is the all clear, yellow and red escalate to a condition the owner has to go look at. The audible alert is the part that matters for an unattended property, since nobody watches a light. The unit also gives its own audio alert when its battery runs low, so a silent monitor is not mistaken for a healthy generator.

Yes. The 6664 sounds an audio alert when its battery gets low. That matters more than it sounds: a battery powered monitor that quietly goes dark looks exactly like a generator with nothing wrong. The low battery chirp is what separates those two states.

Generac 6664. That is the manufacturer part number as well as the model designation, so it is what you order by. It is the wireless, battery powered status monitor with the magnetic back, not an in wall or hardwired display.

The magnetic back sticks to any ferrous surface, so a steel door, an electrical panel cover, a file cabinet, or the side of a mechanical room enclosure all work as well as a refrigerator. On drywall or wood there is nothing for the magnet to grab. Since the unit weighs about 1 pound assembled, a small steel plate or bracket handles it if you need it on a non magnetic wall.

No. The 6664 is not flagged as containing chemicals that cause birth defects under California Prop 65, and it carries no shipping restrictions. For institutional buyers who screen for those flags on every line item, it clears both.
