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
