In effect, your security system becomes less credible. False alarms can cost you big fines in many U.S. cities and towns. In fact, in some instances, chronic abusers may even have police response suspended. To reduce that number, make sure anyone with a key to your home knows how to operate your system. Make special arrangements for guests or repair technicians.
Routine maintenance can greatly reduce false alarms.
Also, call your security company immediately if your system doesn't seem to be working correctly or before you do any remodeling. Remember your security I.D. code. Find out if there really is an intruder or fire and respond appropriately. If the alarm activation was accidental, carefully disarm your system per your system's instructions. After you've reset the system, wait for your monitoring station to call you.
