False alarms can lead neighbors to ignore your alarm when it goes off. In effect, your security system becomes less reliable. 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, and make sure they know the disarm code.
Routine maintenance can greatly reduce false alarms.
Also, call your security company immediately if your system does not seem to be working properly and before you do any remodeling. Do not panic. Remember your code. If it is an intruder alarm, stay where you are unless you can safely exit your home. Do not put yourself at risk by attempting to confront an intruder.
