Abstract
A security monitoring system includes at least one sensor configured to sense an event condition. A security monitoring system controller communicates with the sensor and an indicator of alarm and trouble conditions. The central security system also detects barometric pressure within a monitored area. The security system controller is configured to receive an event signal indicative of an event from the at least one of the sensors and receive an indication of the barometric pressure from a barometer. When the barometric pressure from the barometer indicates a change in barometric pressure, the security monitoring system controller confirms that the event is present and outputs an indication signal to the indicator based on the confirmed event. When the barometric pressure from the barometer does not indicate a change in barometric pressure, the security monitoring system controller suppresses the output of the indication signal.
