Struggling

Thanks. Really helped to hear from the experts

Thank you @sixwheeledbeast . It might be time for an upgrade!! Was trying to avoid it as we got an extension planned soon so was ok with an interim solution and then do an upgrade after the construction! Need to have a think

Hi all you guys really know your stuff....and I clearly don’t. I recently changed the battery on the remote for an Honeywell ADT (TCU3uk) since then the remote and the panel don’t conmunicate, all the panel lights have lit up and the alarm doesn’t work. the alarm isn’t monitored and is about 8 yrs old im comfortable with getting a local engineer around but ADT are quoting £170 for a visit and no promise of fixing it either would welcome your thoughts thanks
