Frankie and colleague kept me in touch with their movements on route and arrived as expected. The guys checked out the current system and found the box in the conservatory was not working and probably beyond repair. They fine tuned the main system and fixed the sensor above the front door. System now checked and working. I showed them my system from my previous house and asked about installing it. They said they would include my request in their job report and I wait to hear back. Very pleased with the two guys who were very friendly, competent and helpful. Thanks guys.
