Indoor Siren Placement

I can't find information on the best place to locate an interior siren for a new-build alarm system. I'd rather not have it visible, so is unfinished attic, or in basement mechanical room good enough to be heard? Should I have one for each level?

For an attic mount of a bullhorn style siren, aim it at a vent or soffit so it can be heard outside of the attic.

For indoors, there a number of unobtrusive, even paintable, siren models that you could put next to the door bell sounder, and it would become "invisible" in no time.

The point of indoor sirens is to frazzle and disorient the thief (loud piercing sounds in enclosed spaces have that affect), and alert sleeping occupants (you wouldn't want one IN a bedroom, but in the hall outside the common sleeping area) - in conjunction with an outdoor siren to call attention to the house. You would want one basically in the central area of each floor.

no rules on just one indoor siren -- run wires for multiple. Some can fit in single-gang boxes.

You can think about an exterior strobe, too.

Best to be a hallway near the bedrooms on same floor. This is because of fire alarms and teenagers/elderly hard of hearing people.

Some teenagers need a train horn in their bedroom to wake up!
