A method of supervising intruder alarm systems, each alarm system comprising a plurality of alarm sensors and at least one gateway communicating with a remote alarm receiving center. The method includes the steps: a) receiving in a first intruder alarm system radio signals transmitted from a second intruder alarm system, b) transmitting from said first intruder alarm system information relating to the received radio signals to said remote alarm receiving center, c) analysing in said remote alarm receiving center information received from intruder alarm systems to identify at least one first intruder alarm system and at least one second intruder alarm system capable of exchanging information via radio signals, d) transmitting from said remote alarm receiving center control signals to said first intruder alarm system and to said second intruder alarm system to operate as a supervising system by monitoring radio signals from the other intruder alarm system operating as a supervised system, e) observing in either one of said first intruder alarm system and said second intruder alarm system absence of the monitored radio signals, and f) transmitting from a supervising alarm system an alarm signal when absence of said monitored signals is detected.

1. A method of supervising intruder alarm systems, each alarm system comprising a plurality of alarm sensors and at least one gateway communicating with a remote alarm receiving center, wherein at least one alarm sensor communicates via a first radio link with said gateway, said method comprising the steps: a) receiving in a first intruder alarm system radio signals transmitted from a second intruder alarm system,b) transmitting from said first intruder alarm system information relating to the received radio signals to said remote alarm receiving center,c) analysing in said remote alarm receiving center information received from intruder alarm systems to identify at least one first intruder alarm system and at least one second intruder alarm system capable of exchanging information via radio signals,d) transmitting from said remote alarm receiving center control signals to said first intruder alarm system to operate as a supervising system by monitoring radio signals from said at least one second intruder alarm system operating as a supervised system; and to said at least one second intruder alarm system to operate as a supervising system by monitoring radio signals from said first intruder alarm system operating as a supervised system,e) observing in either one of said first intruder alarm system and said second intruder alarm system absence of the monitored radio signals, andf) transmitting from a supervising alarm system an alarm signal when absence of said monitored signals is detected. 2. A method as claimed in claim 1, also comprising the step: receiving in a first intruder alarm system radio signals exchanged within a second intruder alarm system. 3. A method as claimed in claim 2, also comprising the step: maintaining in the remote alarm receiving center records of alarm system identities and associated subscriber information, so as to be able to avoid exchanging subscriber information during communication between said remote alarm receiving center and intruder alarm systems. 4. A method as claimed in claim 1, also comprising the steps: including in said control signals instructions to send specifically defined messages, and receiving in a supervising alarm system radio signals comprising said specifically defined messages sent from a supervised alarm system. 5. A method as claimed in claim 4, also comprising the step: including in said control signals monitoring instructions based on a predictable time schedule for sending and receiving radio signals. 6. A method as claimed in claim 5, also comprising the steps: including in said control signals threshold values of background noise levels,measuring background noise levels in said intruder alarm systems, andgenerating an alarm message in any intruder alarm system detecting background noise levels exceeding said threshold values. 7. A method as claimed in claim 6, also comprising the steps: including in said control signals instructions to an alarm system to send echo request signals from a supervising system to a supervised system, andgenerating an alarm message in a supervising alarm system not receiving an acknowledge signal from a supervised system. 8. A method as claimed in claim 4, also comprising the step: maintaining in the remote alarm receiving center records of alarm system identities and associated subscriber information, so as to be able to avoid exchanging subscriber information during communication between said remote alarm receiving center and intruder alarm systems. 9. A method as claimed in claim 1, also comprising the step: including in said control signals monitoring instructions based on a predictable time schedule for sending and receiving radio signals. 10. A method as claimed in claim 1, also comprising the steps: including in said control signals threshold values of background noise levels,measuring background noise levels in said intruder alarm systems, andgenerating an alarm message in any intruder alarm system detecting background noise levels exceeding said threshold values. 11. A method as claimed in claim 10, also comprising the steps: including in said control signals instructions to an alarm system to send echo request signals from a supervising system to a supervised system, andgenerating an alarm message in a supervising alarm system not receiving an acknowledge signal from a supervised system. 12. A method as claimed in claim 10, also comprising the steps: receiving in a first gateway of a first intruder alarm system radio signals transmitted from a second gateway of a second intruder alarm system to alarm sensors included in said second intruder alarm system, and transmitting from said first intruder alarm system information relating to the received radio signals to said remote alarm receiving center. 13. A method as claimed in claim 1, also comprising the steps: including in said control signals instructions to an alarm system to send echo request signals from a supervising system to a supervised system, andgenerating an alarm message in a supervising alarm system not receiving an acknowledge signal from a supervised system. 14. A method as claimed in claim 13, also comprising the steps: receiving in a first gateway of a first intruder alarm system radio signals transmitted from a second gateway of a second intruder alarm system to alarm sensors included in said second intruder alarm system, and transmitting from said first intruder alarm system information relating to the received radio signals to said remote alarm receiving center. 15. A method as claimed in claim 1, also comprising the steps: maintaining in the remote alarm receiving center records maintenance schedules and similar information regarding intruder alarm systems, andutilizing said information when receiving alarm signals to avoid unnecessary alarm activities.
