Big one family dwelling with 12 (maxium allowed on one zone) inter-connected hard wired (120 volt) with battery back-up located in the dwelling and approved by the local authorities...sooo now the owners purchasing the property are unable to get home owners insurance on the dwelling unless there is a "monitered" fire alarm system installed in the dwelling! Apparently as of Janruary 1st 2004 in MASSACHUSETTS the insurance industry has a new rule applying to homes and contents worth more than a million dollars to have a monitered fire alarm system.Any input on this???
