Imo, this is wrong, and would lead to ignored alarms. (Who's old enough to) Remember waiting for someone else to answer the landline? Versus it ringing when you're home alone and know no one else is going to get it? Multiple alarm monitors might result in a lack of urgency (ie, someone else is closer, so no rush) or even shrugging off the responsibility all together (ie, someone else will get it, I don't need to go).
