Ade Optima Compact Gen4 Intruder Panel, Transformer Keeps Burning Out?

[phil_ad]

Installed this alarm in my grandparents house when they first moved in. Everything was fine for first few months, then the transformer burnt out. Replaced it with a new one, and sure enough, few months later same happened. On third panel now and its happened again! Has anyone had this same trouble or know what the problem could be? The fuse inside the fuse spur doesn't blow and neither does the fuse inside the panel it self.. Luckily I know the lad down the wholesalers so its not costing us to replace the panel every time. The panel doesn't really get used that much only use when they are out most the day, so its not like its getting over used either.

Any suggestions?

Try a decent panel instead?

and...

is the incoming side checking out OK when you test it?

[phil_ad]

Incoming side is fine, 240v up to the transformer, and then out of the transformer, nothing. First thing I check when it happens to make sure its nothing to do with the incoming mains.

[Ronnie]

Incoming side is fine, 240v up to the transformer,

thats not what I said..

[phil_ad]

well what do you mean by incoming side?

[Ronnie]

well what do you mean by incoming side?

the incoming mains - does this test ok within the recommended limits? what is the output from the transformer when commissioning (before it goes wrong obviously)?

[phil_ad]

The incoming mains is 240v up to the transformer and the output from the transformer is 15v AC

[Ronnie]

The incoming mains is 240v up to the transformer

still not answering my question, perhaps someone else can help you out here. good luck.

i don't understand what you are asking, do you mean the main cable into the house and into the meter? This is all okay, 240 between L-E and L-N and obviously nothing between N-E.. Sorry but not understanding what you mean when say incoming mains. That to me just sounds like your asking for the mains into the panel.

now you answered the question. i'm trying to establish the base line readings here (start with the basics and work your way up and you'll find something wrong somewhere) and "nothing" is not normal. are you sure it's nothing N-E?
