Extremely useful visit to a new home with existing alarm (and clueless owner). Showed me how to work it, reset the entry and exit times and zones to suit me, explained wiring and alarm history and now I have someone to call if I have a problem. Extremely fast response despite festive period and friendly and careful engineer. Definitely recommend.
