How do I test my system?

We recommend testing your system monthly. To test your system, just call the Monitoring Center at (844) 425-5787 and give them your account number or address to look up your account, then give them your password and ask for your system to be placed on test for 1 hour. Then you can arm your system, and trip/open a zone or two (or all of them) wait for approximately 30 seconds after tripping the zone, then go ahead and disarm your system and call the monitoring center back and ask if they received the alarm signal. if yes, you can ask them to take your system off test.
