Doorbell with 16VAC 1.5A power supply (no chimebox) keeps causing failure of power supply

[PaulM1253]

Hi guys I've been trying to get my wired video doorbell going over the past 18 months.  I wanted the wired version of the doorbell to ensure I always have at least one camera running on power at all times.

I am located in Australia (240VAC is the standard) I have ultra cameras/base at the front of my property with Pro3 cameras/base at the rear of my property.  I am heavily invested with Arlo at this point therefore I'm reluctant to throw the system away.

As I do not have an existing doorbell, I opted to supply power to the Arlo wired video doorbell by purchasing a 16VAC transformer (see image)

I have purchsed an Arlo chime unit to pair with the doorbell.

With the initial installation (by a licensed electrician), the doorbell powered on, worked for about 5-10 minutes, then lost power.

The electrician was convinced the Arlo unit had failed as he rarely sees transformers fail, therefore I purchased a second Arlo wired doorbell as a replacement.  That second unit also failed to power on using the installed transformer.

The transformer was replaced with the same model transformer (images above).  The (just purchased) second doorbell worked on the new transformer for 24 hours before losing power.  I have to assume the transformer has failed again.

My question - is there anyone local to Australian conditions who has successfully installed one of these using a power transformer instead of an existing doorchime?  What power transformer was used?  Any tricks to get these going?  Its getting bloody expensive to keep pushing on, given I've bought two units and I'm getting the electrician to do the work.

While a gesture of help is a good thing, please dont respond if you haven't personally been involved in an Australian  installation of this type (as a professional electrician or otherwise) so that we can provide meaningful answers to people who need genuine help.

Thanks - Paul.

It seems like no-one has really had a similar problem or they have not solved anything similar either. I do note that there are a number of posts that refer to "heating up" of the doorbell and the camera not working which I conclude might be related. I'm still fatally optimistic that the doorbell (the second one I purchased at least) will work but I'm seeking the special sauce that makes it run without a wired chime. Arlo products are definately for the technical enthusiasts and less for the general public due to the nature of what they do. Heavy on engineering and light on simplicity.

If you switch the powerkit to bypass mode, then the chime is essentially disconnected from the circuit.  You could also just connect the wires from the doorbell and transformer together at the the chime (not connecting them to the chime at all).  Then no power kit is needed.
