Do not leave your home until you have spoken with your monitoring station. Rehearse alarm cancellation with anyone who might use your system. Make sure everyone who has a key to your home or business knows how to operate the security system. Keep your security system instruction book, and your monitoring station's name and phone number handy. If you give anyone your key, train them in the proper use of your alarm system.
Many systems offer temporary codes that only work a set number of times.
When the alarm system is armed, be sure all doors and windows are shut tight and locked. Be sure pets are outside or in a room without alarm coverage. Check for drafts or wind or vented air that could blow plants, curtains, balloons, etc. Tell your neighbors about your alarm system. Test your system monthly, or at least yearly.
