Where?

If you get the same manufacturer as the panel you will have EOL OOTB. I don't really rate those cheap Honeywells, some nice quads will be much more reliable. Much better down the line to have end-of-line than double pole to diagnose faults.

Should be compatible if you wired as double pole with commoned tampers. I'd probably replace them.

Lidl bakery useful. Aldi don't like at all.

Morrisons is a bit posh for up here... Heron or Farmfoods maybe?

I don't know of any panel that would chime on close. Yep, as above using a Mimic output and some other logic like a toggle relay or custom outputs would be the way to go.

Then I would suggest monitoring in that case.

Like most sounders the Twin alert manual has the wiring instructions for different manufacturers. Aux Tamp / Aux Tamp / Bell / Spk- / 0V / +12V

Not used one. Is the strike time really short? Does the strike lock require the same voltage as the KP? Have you tested your findings with a multimeter? Is it just not wired correctly or some other simple mistake?

It does both. Allowing walk through for Full set and switching to entry for Part sets.

As JW stated the charging rate is in the standard. Larger premier panels have a charging rate selection jumper so you can adjust the rate depending on the battery and make sure it conforms.

If you keep pressing the info/OK button it should run through the faults. If the faults are clear it will let you arm/disarm to clear.

Yep I'd also assume the PIR's are in Auto and sleeping. Door contacts shouldn't do that unless you have programmed them incorrectly. They default to always awake.

Most panels have NVM locking but it's down to the installation company as to if it's used. We don't provide defaulting information here as per our guidelines. It can be argued the programming is intellectual property of the installer. Locking would provide protection against others changing the system configuration then blaming the original installer for a FTO. The charge to come out to reset the codes means they have in writing they have transferred ownership of the system to the customer or their maintainer, it's important due to above. As it's a Gardtec 800 I'd say it's well past it's best and for the bin, just replace it and have done with it.
