Anybody know of a no monthly fee alarm system?

[Colin Nelson]

Hey Everyone. Happy Holidays

I own a 3 family apartment building in a C+ neighborhood in St. Louis MO. Upon buying this property I noticed that all three units were hardwired with an alarm system. Only one works currently.

The alarm sounds but that's it. It's not hooked up to a monthly service, the police aren't notified or anything. This actually works. I'd love to market the property highlighting the alarm system without the additional cost (Of course, I'd let me tenants know it only sounds)

Problem is, I don't know where to go to get my other two apartment wired in the same way. I've heard I can sign up with a no contract system then just pay for installation......anybody ever went this route? Or have a better solution?

Just trying to make my property safer with as minimal cost as possible. Thanks in advance for the help!
