An alarm system for detecting and reporting “smash and crash” intrusions is described. The alarm system includes a plurality of intrusion sensors and a security alarm panel in communication with each of the plurality of intrusion sensors at the site of the alarm system. An alarm gateway is provided remote from the security alarm panel, the alarm gateway monitoring the status of the security alarm panel for indications of tampering. A central station is in communication with the alarm gateway and monitors the status of the alarm system, where the alarm gateway sends an alarm condition to the central station when tampering at the security alarm panel is detected.
