False alarm reduction in security systems using weather sensor and control panel logic
First Claim
1. A security apparatus, comprising:
- a control for controlling a security system that secures a building;
a first sensor for detecting an intrusion into the building; and
means for determining whether a weather condition is present in a vicinity of the building;
wherein the control determines whether to trigger an alarm responsive to an intrusion detection signal from the first sensor, and a signal from the detennining means indicating whether the weather condition is present.

Abstract
A security system that secures a building includes a weather detector for detecting weather conditions, such as thunder or high winds, which are likely to cause false alarms in sensors such as an acoustic glass break sensor, shock sensor and vibration sensor. The weather detector may include a sensing component that senses atmospheric conditions external to the building, such as temperature, pressure, wind speed and/or lightning. The weather detector may also include a component for receiving a data communication, such as from a radio, Internet, or telephone link, indicating that the weather condition is present in a vicinity of the building. The security system operates in a bad weather mode by requiring corroboration of intrusion detection signals from the sensors that can cause false alarms.

12. A method for use by a control of a security system for securing a building, comprising:
-
receiving a signal indicating whether a weather condition is present in a vicinity of the building; receiving an intrusion detection signal from a first sensor of the security system that detects an intrusion into the building; and determining whether to trigger an alarm responsive to the receiving the intrusion detection signal from the first sensor, and according to the signal indicating whether the weather condition is present. - View Dependent Claims (13, 14, 15, 16)

17. A program storage device, tangibly embodying a program of instructions executable by a control in a security system to perform a method for securing a building, the method comprising:
-
receiving a signal indicating whether a weather condition is present in a vicinity of the building; receiving an intrusion detection signal from a first sensor of the security system that detects an intrusion into the building; and determining whether to trigger an alarm responsive to the receiving the intrusion detection signal from the first sensor, and according to the signal indicating whether the weather condition is present. - View Dependent Claims (18, 19, 20)

21. A system for securing a building, comprising:
-
a control operable to receive a signal from a weather detector, the control further operable to receive an intrusion detection signal from a first sensor and to determine if the first sensor is of type that is subject to indicating a false intrusion detection due to the presence of the weather condition, the control further operable to determine if a corroborating intrusion detection signal is received from a second sensor; and decision means operable to decide to trigger an intrusion alarm when a weather condition is present and when the intrusion detection signal is from a sensor that is of type that is subject to indicating a false intrusion detection due to the presence of the weather condition, if a corroborating intrusion detection signal is received.
