I accidentally made my alarm ring but the station did not call, why?

Most systems are programmed to send an “abort” signal or a “disarm” signal.  If your alarm rings but is disarmed with a user code, the system will send the alarm plus the “disarm “or “abort code”.  The “abort” or “disarm” lets the station know that the alarm was caused by user error and no further action will be taken (provided that the abort signal shows within 120 seconds of the alarm signal).

This feature helps cut down on false alarm response.
