There likely would be a reduction in premium for having such a system - at least from reputable insurers. The problems are 1) as Rob suggests you cannot do it yourself and 2) the premium reduction is based on the probability of a fire in the first place, which works out to less then the extra monthly cost (mortgage) of the system. Great if you want it and can afford it but a real bummer if it is that final cost that pushes the house out of what you can afford.
