BarTender:

If you go for a cheap low end Eaton UPS and then plug it into your computer you can turn off the Beep if you install their management tool.

As long as it supplies enough power for the garage.

I personally like the beeping, as then you know it's currently on the battery and then when the battery stops it's either the battery is dead or the mains is back on.

Thanks for that, I will look deeper in to it.

I dont need the beeping we have lots of other indications that the power is off :-)

SATTV: 600VA should be fine, 100VA better, I dont think the door would use more than 1/2 horsepower or approx 375W and there is nothing in the manual.

Check the inrush current on that, if it's an induction motor a UPS will shut down or, for a cheap UPS without proper protection circuitry, cook itself trying to drive it.

Having a battery version/accessory makes it very likely to be a DC motor, usually with speed control. It's not going to be a brute force induction motor. You don't see those other than on very slow, large commercial doors.

We have a Chamberlain which has the option of connecting a 12v battery. I haven't fitted a battery to ours so my information may not be 100 % correct. I know for sure the motor is 12v and the lamp is also 12v and are powered from an internal 12v power supply which is fed from 230VAC.

I'm fairly sure the battery (when equipped) is wired to two terminals under the cover and sits in parallel with the 12v output from the power supply.

A pretty simple set up and easy to add the battery to. It would surprise me if the Garador was any more complicated.

In short, buy a bracket and attach the battery directly to the door opener?

I think so but not sure. Ceratinly wouldn't expect ¬ $1000 to do it. A bit mystified by the insistence to also fit beam sensors, this is probably where the major cost is.

I'd be looking at fitting the battery myself.

The manual indicates a 24V light, so I imagine the battery might need to be 24V as well. Certainly not hard.

Yes the backup battery is 24v, but the connector is a 5 pin connector, I have no idea what pins are what and if there are any other smarts otherwise why would you use a 5 pin connector rather than a 2 pin connector, it possibly is to keep people from adding their own.

The other issue however is how do I dangle two batteries from the ceiling?

At least the Garadoor battery backup comes in a case, just screws to the ceiling and connects I guess.

It has to look good, the garage is no longer my domain exclusively.

I just dug up the quote, 31 July 2023.

Battery $352 + GST

safety Beams $295 + GST

Technician $130 + GST ( first 15 mins )

Have you asked them to explain exactly why beams are required when adding a battery backup system?

All you are doing is adding battery backup for the occasional time that there is a power outage.

Does the door have some automatic function to open or close the door when power is cut?

I am at a loss to understand this requirement.

They seem insistent on putting those beams on whenever they do work on garage doors. Tried to upsell a friend on a correct installation for the beams when they were warranty sorting out a failed inside button.

SomeoneSomewhere:
I can confirm that despite having the option (at least in the linux drivers) to disable the beeper, my cheapo Dynamix Eco UPS 1000 still beeps.

Disabling a buzzer in hardware is pretty easy though; desolder, or glob it up.

Also, on cheapo UPSs, the general buzz of the equipment can be almost as loud as the beeper when providing backup power.

I can confirm that on the Eaton UPSs when I disabled it using NUT ( Linux UPS tools ) I was able to disable the beep. And when I unplugged it, moved it and plugged it back in without USB cable and had some load it didn’t make any beep. My APC also behaved the same way.
