Abstract
A method of operating a security system includes providing a plurality of sensors, and detecting at least one event with the sensors. A decision whether to initiate an alarm signal is dependent upon the detecting by each of the sensors, which of the sensors has detected the at least one event, and what nonzero number of times a first of the sensors has detected the at least one event.

A method of operating a security system, said method comprising the steps of:
- providing a plurality of sensors;
- detecting at least one event with said sensors;
- deciding whether to initiate an alarm signal, said deciding being dependent upon:
- said detecting by each of said sensors;
- which of said sensors has detected the at least one event;
- and
- what nonzero number of times a first of said sensors has detected the at least one event;
- and
- assigning a numerical value to each of the event detections by said sensors, the numerical values being dependent upon which of said sensors made the event detection, said deciding step being dependent upon a sum of the numerical values.
A security system comprising:
- a plurality of sensors, each of said sensors being configured to detect at least one event;
- a control device in communication with said sensors and configured to decide whether to initiate an alarm signal dependent upon:
- said detecting by each of said sensors;
- which of said sensors has detected the at least one event;
- and
- what nonzero number of times a first of said sensors has detected the at least one event;
- and
- said control device also being configured to assign a numerical value to each of the event detections by said sensors, the numerical values being dependent upon which of said sensors made the event detection;
- and to initiate the alarm signal dependent upon a sum of the numerical values.
A method of operating a security system in Away and Stay modes of operation, said method comprising the steps of:
- providing a plurality of sensors;
- categorizing each of said sensors in one of at least two categories;
- detecting at least one event with said sensors;
- issuing an alarm signal dependent upon said detecting step, wherein a sensor of a first of the categories must detect the at least one event twice in order to cause the alarm signal to be issued, and a sensor of a second of the categories may cause the alarm signal to be issued by detecting the at least one event only once;
- switching said security system to a Stay mode of operation;
- and
- deciding in the Stay mode whether to issue an alarm signal dependent upon said detecting step, wherein a sensor of a third of the categories must detect the at least one event three times in order to cause the alarm signal to be issued.
A method of operating a security system, said method comprising the steps of:
- providing a plurality of sensors;
- categorizing each of said sensors in one of at least two categories;
- detecting at least one event with said sensors;
- issuing an alarm signal dependent upon said detecting step, wherein a sensor of a first of the categories must detect the at least one event twice in order to cause the alarm signal to be issued, and a sensor of a second of the categories may cause the alarm signal to be issued by detecting the at least one event only once;
- and
- assigning a numerical value to each of the event detections by said sensors, the numerical values being dependent upon which of said sensors made the event detection, said issuing step being dependent upon a sum of the numerical values.
A method of operating a security system, said method comprising the steps of:
- providing a plurality of sensors;
- deciding whether to initiate an alarm signal dependent upon whether said security system is operating in a Stay mode or an Away mode, wherein each of said sensors is capable in each of the operating modes of independently causing a decision to initiate an alarm signal;
- and
- assigning a numerical value to each of at least one event detection by said sensors, the numerical values being dependent upon which of said sensors made the event detection and in which of the operating modes said security system is operating, said deciding step being dependent upon a sum of the numerical values.
