Veritas R8 Unset Flashing

[Mxal]

I’ve a Veritas R8 panel with the unset light flashing. Not a duplicate thread as:

I checked battery output as was dead
Checked fuse … ok
Replaced battery … fault persists
Closed panel and enter code + reset 2x … fault persists

I’m now not convinced the panel is recharging the battery when required or drawing power from it?

Tested with multimeter, new battery output is perfect at both the battery terminals and also connectors on the panel board ( from fly leads ).

I then disconnected the negative terminal at the battery, went positive to positive on the multimeter, and negative lead to the negative fly lead … no voltage!

Any ideas? Fault panel or otherwise?

Could a dead battery in a bell box cause this power unset light flashing too perhaps … not checked that yet.

Thanks in advance.

Remove battery …what’s coming out of battery leads ? Should be around 13.8 v dc ….if nothing REMOVE battery fuse to test it , if it’s ok ….bin panel

I’ll check the voltage from the battery leads with battery disconnected when I return … haven’t checked that yet - thanks.

When measuring the battery when disconnected the voltage was just over 13 v dc - cant remember the exact decimal.

I have previously removed, tested and also replaced the glass fuse - removed fuse was fine but I put a new one in to rule out the fuse.

Is it a new battery?

Have you checked, mains power in 230V, ac power out of transformer about 18/19V AC.

Flashing unset light indicates power fault not necessarily battery fault of memory serves me correctly.

I know it may be a little late but hopefully this may help people having the same issue at some point.
I had the same problem and, having tested the soldered power fuse F5, I assumed it was the transformer. I tested the power in to the connector block and it was OK.
After further investigation I found that the wire out of the connector block wasn't live
I found a little known glass fuse to the right of the transformer and where the power comes into the unit. (the connector block)

I then spotted a black pull out slider in the connector block and lo and behold there was a fuse in it and it had blown. There was a spare fuse underneath.
Once I replaced the fuse all was OK.
I'll try to post a photo in the next couple of days

Following my previous post I've now attached photos of the fuse location.
