Definitions
- the present invention relates to a method and a device for deploying a link between at least one security system and an alarm center. It applies, in particular, to the protection against the risks of sites such as dwellings or industrial or industrial sites for example.
- the term "supercapacitor” refers to a capacitor having a power density and an energy density between the batteries and the conventional electrolytic capacitors.
- a "site” is a place with at least one room corresponding, for example, to a room.
- sensors capturing a physical quantity whose value may represent the danger, such as temperature for example,
- a central unit receiving the values transmitted by the sensors, detecting an anomaly in a physical quantity sensed by a sensor and
- actuators such as trap opening pistons for the evacuation of smoke for example, operated under the control of the control unit, when an anomaly is detected.
- each sensor and actuator is wired to the control panel.
- these sensors and actuators are wirelessly connected to the control panel.
- the disadvantage of current wireless technologies is that the wireless transmission between a sensor or actuator and a central is fragile in view of the distances that can separate the central sensor or actuator.
- the surrounding electromagnetic noise of a site thus secured can be a source of transmission defects between a sensor or actuator and the central.
- these systems either are used in small premises, or have a plurality of plants to limit these transmission problems or repeaters that relay the transmitted signals, which increases the cost of maintenance and the risk of failure .
- the pairing between the control panel and a sensor or actuator is made by pressing a button on the control panel and a button on the sensor or actuator.
- this sensor or actuator When pressing the button of the sensor or actuator, this sensor or actuator transmits a pairing signal.
- the button of the control unit is also pressed or has been pressed within a period of time less than a predetermined limit value, the pairing between the sensor or actuator and the control unit is performed.
- each actuator or sensor thus paired near a central is then positioned in the site to be secured.
- each sensor or actuator comprises an identifier representative of the intended location of the sensor or actuator.
- WO2005 / 1 19609 which teaches a wireless communication implementing a spread of the frequency spectrum of the communication.
- this document does not solve in particular the problem of the reliability of the location information of a sensor.
- this document does not teach a solution to the problem of positioning error of a sensor / detector / actuator by a system operator.

- the surrounding electromagnetic noise can be a source of transmission faults between an outlet and the plant.
- these systems are either used in small premises, or have a plurality of plants to limit transmission problems or repeaters that relay the transmitted signals, which increases the cost of maintenance and the risk of failure hardware.
- these current systems have unidirectional and downlink communication from the control panel, which prevents the control panel from obtaining any information from the outlet.
- the opening of an opening is controlled by the control panel when a fire is detected. Except for some fires, it is better to limit the amount of oxygen present in the room where the fire occurs. For all of these reasons, the current wireless systems for securing a site do not make it possible to respond optimally to the reliability constraint of the normative duration between two tests of operation of the device.
