Your system may be programmed for an Automatic Timer Interval (ATI) periodic test. This programming watches for a specific signal from your system approximately once a month. If we do not receive that signal, our system generates a “Late To Test” signal, which may indicate a communication failure. We will call you to notify you of the “Late To Test” status and request your help troubleshooting by placing your account on test and testing the communication of your alarm system. If we do not receive a signal during testing, we will set up a service call for you so a technician can be sent to your location.
