Has anybody here put a smaller commercial (low voltage) fire alarm system in a home? I have a frequent customer who bought an older house that only has 3 somke detectors, the house should have about 10 (it's big). He has 6 kids to worry about and would like to have a fire alarm system that dials out and can display the triggering device. May also want a duct mounted detector as well. Obviously, this is going to take a little more than a FireX set of interconnected smokes. I have only done a little FA work, and I'm not hip to what's current. Anybody have any good sources of info on these systems? How would you do it? What comapnies should I look at for products? I would like detectors and alarms that are more "residential" looking, ie no giant red strobes that say FIRE on them!

Thanks for any ideas,
Mike
