Fenwayfool sounds like someone from Boston. We have a park/garden/pond/stream area in the Back Bay area of Boston called the Fenway. Some call it the Fens. A Central Park if you will, but on a much smaller scale. Nice place for a stroll to watch the ducks/geese/squirrels/flowers in the summer.
From home plate at Fenway Park, of Boston Red Sox fame, one could hit a baseball over the wall and it would almost land in the Fens.
We install, monitor, service, and provide an all-inclusive "Monitoring and Service" policy for all systems that we install. Customer owns the system. Parts and labor to repair and service our systems, all residential, are at no additional cost to the customer when they have a problem with their system -- as long as they remain connected to our CS -- and of course continue to pay our semannual invoices.
Our contract states that the system is not to be serviced by any person other than our employees; that if it is serviced by anyone else, it is our option to terminate the agreement.
The danger of other persons adding to the system or otherwise making adjustments, moving contacts, keypads, etc. is the liability that it presents to us. The last thing I need is a system that malfunctions at a time when it is really needed - because some Fenwayfool knowitall became his own expert technician.
In forty-four years we have never been sued.
Knock on wood.
The statements made by Fenwayfool reflect his choice of moniker.
