Well im thinking back a bit now from when they moved in.. Cannot be 100% sure but will double check and get back to you tomorrow. Multimeter is currently still at work on site. for the help so far and will post my readings tomorrow.

if the transformers burning out i would suggest its overloaded.

You cant rely on the fuses to prove its not overloaded as they wont blow till current is past 1.8A and the panel cannot provide that for long.

Need to know your day mode current and battery charge current.

Try a decent panel instead?

I think this is a cracking little panel for the money. Plus we still have optima 1's we installed in the 80's going strong.

QFA

Haven't used them to be honest but anything with "optima" in the title suggests to me it's long past it's day..

I installed a load of these a few years back, but once I got onto the Galaxy panels with LCD keypads I gave up trying to understand the stupid LED keypads that the optimas/accentas had!

you can put an lcd keypad on an optima and a prox reader
