Abstract

The present invention is in the field of the security of goods and the subject is more particularly an electrical installation whose function is to simulate the presence of a person in a premises with a view to deterring burglars. According to the invention, an electrical installation comprising a general interrupter 1 is characterised in that it furthermore incorporates means termed changeover switches for powering and alternately switching off, according to a preset programme, one or more of the said instruments 8, 10, 12, 13 and 15 of the premises, said changeover switch means comprising a clock 3 and a plurality of interrupters 4. Application to the security of goods by deterrent.

Description

 The present invention is in the field of security of property with regard to intruders and it relates more particularly to an electrical installation having the function of simulating the presence of a person in a room with a view to dissuading burglars from entering the local.

 While many alarm systems are known based on the detection of the presence of an intruder in a room, the invention proposes means aimed at preventing the intrusion rather than noting it.

 According to the invention an electrical installation equipping a residential or professional premises containing in one or more rooms lighting means, radio or television sets and in general light and / or sound generating apparatus. , said installation further comprising a general switch of the electrical supply and a distribution board, is characterized in its generality in that it also incorporates means known as switches for supplying and alternately switching off, according to a preset program, one or more of said local instruments, so as to simulate a human presence in the local and thus deter intruders.

 Preferably the switching means comprise a clock and, depending on the clock, a plurality of switches each mounted on a supply line of a said device. Advantageously, the clock is an electric clock supplied with energy by the line at the output of the general switch, each of said switches being located between the latter and a fuse in the distribution panel.

Alternatively clock could be a clock powered by battery or by battery which, at the cost of periodic recharges puts the progress of the program safe from "breakdowns" in the sector.

 According to a first alternative embodiment, said switching means are of the electromechanical type comprising a plurality of cams driven by the motor and a plurality of switches controlled by the cams. Such programmers are widely used in the control of household appliances, machines, etc .; they are very reliable and although of a fairly high unit price, require little investment for their adaptation.

 According to a second alternative embodiment, said switching means are of the electronic type and comprise a quartz clock, a logic circuit comprising the program, and a plurality of transistors under the dependence of the logic circuit, and power relays under the dependence of said transistors. Such programmers have fairly low costs for large series, but on the other hand require the investment of programming a circuit which will preferably be an integrated circuit. A more elaborate version of this second variant incorporates as a programming circuit a microprocess that the user can reprogram as desired.

 The present invention will be better understood from the description which will be given in relation to the figure of the single appended sheet which schematically represents an electrical installation of the invention.

 In FIG. 7a, a general switch 1, a circuit breaker, receives the electrical power from a meter (not shown) and its output 2 is, in general, accessible to the installer or to the user in the example of the figure. the output of a circuit breaker is connected on the one hand to a timer programmer 3 which controls, either mechanically, electrically or electronically, the switches to a battery 4 of switches; each switch is mounted on a line comprising a fuse such as 5, each line supplying either a room in the room or a specific device. For example, in the case of the figure, a line such as 7 can supply a television set 8, a line such as 9 can supply a light bulb 10, a line such as 11 can supply a radio device 13. A line such as 14 can supply external lighting 15, a line such as 16 can supply a tape recorder 17 on which would be placed a pre-recorded tape of conversation of the usual occupants of the premises, etc.

 It should be understood that the characteristic part corresponding to the invention is the switch-programmer assembly 3, 4 the switches of which will assemble the switching function can be placed both upstream of the line fuses and downstream of them. this.

 The program of the programmer 3 will be, for example, such that the television set 8 is powered during the hours following meals, such that the switching off of a device in a room is followed by the switching on of the lighting in a room neighbor, etc ... such, finally, that the presence of a normal occupant of the premises is simulated.

 It should be understood that the scope of the present invention is not limited to the electrical installation shown above, but that it extends to any electrical installation having the general characteristics stated above.
