We send an officer to most every alarm call. If we get more than 3 unfounded calls in one shift, the road supervisor can make the decision not to respond.
I'd say about 99% of our alarm calls (in total, fire and police) are unfounded. However, we have had a few holdup alarms that were real. I really wish we'd start fining them, it might cut down on the amount of calls we receive; At the very least we'd get some extra money for the dept.
But for our agency, as was stated in the "officer to every call" thread, we send an officer to most everything per the SOPs. Fun fun!
