In some embodiments, the light barrier (21) is an infrared barrier, preferably an infrared barrier with four beams. This light barrier can communicate without a wired link with the alarm center, for example with radio communication, and can operate with batteries or a solar battery. The use of a light barrier saves installation and maintenance time and saves money, since it will no longer be necessary to make trenches in concrete or asphalt to pass cables. The light barrier may include radio transmitters, whether or not via a wave amplifier, received by receivers of an alarm system (or alarm center) which signals a detection of movement to the central monitoring station. (or mobile application or the police or firefighters).

Thus, the light barrier allows:

- a delimitation of the zone or zones to be marked for electrical stations,

CRM / 02 / EN

- detection of movements near the marked area,

- unauthorized intrusion detection of the area marked by a break in the light barrier,

- a transmission, which can be in real time and remotely, to the alarm center of this intrusion which will inform the central monitoring station or the mobile application.

In certain embodiments, as shown for example in FIG. 1, the light barrier can be placed on beaconing devices (B) of the electrical stations, in order to delimit the area not to be crossed.

In certain embodiments, the central alarm unit (3) can be a wireless alarm center, for example with radio communication, and can operate with batteries ensuring its autonomy for several years. This alarm center is preferably for outdoor installation and may include a waterproof housing. The central can be configured to transmit its reports and alerts to the monitoring center or mobile application, thanks to a GPRS module ("General Packet Radio Service" defining a network protocol for mobile telephony derived from GSM and complementary to it) which can be integrated in the control unit. This central alarm unit can be configured to trigger an alarm when the central unit's enclosure is opened, in order to ensure self-protection against any harmful or unauthorized act. The alarm control unit may also include a storage means for memorizing the various characteristics of the control panel (for example the state of opening or closing of the case, the serial number, the firmware revision, the state of the batteries , etc.) or the events of the beacon system (for example the recording of surveillance video of the marked area). Thus, the alarm center can make it possible to record and store the various activities and events of the system which can be consulted remotely by the central monitoring station or mobile application. The power plant

Alarm CRM / 02 / FR can also include a movement analysis software near the marked area, allowing to signal the police or firefighters in the event of unauthorized intrusion into the area (s) signposted.

The console can communicate securely, encrypted and regularly with the control panel. The console can include an alphanumeric keyboard and a reader badge to enter all the settings and parameters of the alarm center, for example according to the administrator rights granted (for example: level 1 assigned to users up to level 4 assigned to the administrator), authorized time slots, alarm parameters, authorized intervention for maintenance, event log / history, etc. The console can incorporate an audible alarm that beeps during the entry and exit delay to activate or deactivate the alarm. This console can be configured to trigger an alarm when the console is opened or destroyed, in order to ensure self-protection against any harmful act or unauthorized intervention. Finally, the programming console may include an indicator, preferably a diode

CRM / 02 / FR bi-color electroluminescent (LED), indicating the operating status of said console.

In certain embodiments, the signaling device (30) comprises an alarm siren (33) for emitting an audible and / or voice alert.
