A good quality toroidal transformer should also not suffer load losses if they are correctly rated. Toroidal transformers are a better design and inherently have much lower core losses than a more traditional transformer. So to fix this in my panel, I have replaced the transformer with a toroidal type. Moreover, there is the question of long-term reliability which I feel would be a problem for this application there is nothing so simple and reliable as a transformer. Switchmode PSU’s are excellent for high power levels and small spaces, but they do suffer from power losses too. I had two options, replace with a Switchmode or replace with a better quality passive transformer.

I did not want to install the panel with this heat-generating cheap-ass transformer, so I decided to fix it.
The transformer in this panel suffers from both problems quite severely, its a poor quality transformer. The heat generation is caused primarily by resistance in the iron core of the transformer. The second source of loss is Core Loss, which is where the transformer consumes power it’s self, even when no load is present. Cheap copper alloys have higher resistance generally, as you draw current through the wire, heat is generated as a result of the resistance in that wire. The first is known as load loss and is as a direct result of resistance in the copper wire that makes up the transformer windings. There are two sources of loss in a transformer. The quality of the design and construction of the transformer play a big part in how efficiently the transformer performs. The transformer is an Iron Core transformer, typical construction that most people are familiar with, and these types of transformers are known to have some inherent inefficiencies. Looks and feels good quality, but performs quite badly I bought a second panel and transformer, and low and behold the transformer was just as bad. It was getting hot enough that I thought there was something wrong with the transformer. Now with the lid on, and with the panel installed in an enclosed space, this is not ideal. I measured it at around 55 degrees Celcius. One of my first observations when running the panel on my desk was how hot the mains transformer was running. I do plan to write some other, possibly more interesting articles about this system and its overall hackability, but I thought I would start with a simple one, the mains transformer – which actually sucks! Here is why… This is also a very “hackable” system making it friendly for DIY’ers and IoT systems and experiments and stuff. On the second-hand market (aka e-bay) they are not very expensive and are still relatively modern systems.

These alarm systems are quite advanced, professional intruder alarm systems made by Honeywell and from hardware design and overall architecture are most definitely on the professional end of the scale. I recently replaced my current intruder alarm system with a Galaxy Dimension G3-520.
