I don't think this is your problem. It's an alarm problem. You just need to provide a means to trigger an alarm. Hereabouts a normal is a fire alarm system in common areas with an attached peizo in each unit and local smoke alarms throughout the units. But I don't care about this as the sprinkie. I supply a means to alarm from a flow. The rest is someone else's work. Local exterior alarm is another thing altogether. Don't work too hard solving someone else's (usually the GC) problem.
