STICKER FOR ALARM SYSTEM

Abstract: A label for an alarm system is built together with a light source, preferably a light diode, and an integrated electronic circuit causing the light source to flash. The flashing diode makes the alarm warning highly conspicuous, particularly in dim day light and darkness.

Description: STICKER FOR ALARM SYSTEM Self-adhesive labels e.g. with printed warning - ALARM - are known and extensively used in connection with burglar alarms. The text on the labels may vary, but their purpos is the same, viz. preventive warning that house/car/firm are secured with a burglar alarm system. Particularly in case of car alarms a great preventive effect has been observed when such a label has been adhered on the inside of the car window. In some systems of car burglar alarms, the instrument pan or the window of the car may have adhered to it a small plastics box, which accommodates a flashing control lamp. The purpose is partly to control that the alarm is connected, partly to warn that the burglar alarm is active . The invention concerns a label for alarm systems, and its object is to provide such a label whose warning effect is enhanced by simple and inexpensive means. This object is achieved in that the label is constructed as stated in the characterizing portion of claim 1, since the light source will call attention directly to the label particularly, of course, when it is dark or dim. Various expedient features are stated in claims 2-6. When a flashing label is to be adhered to e.g. a glass pane, the protective paper is removed from the adhesive front side of the label, as is the case with other self- adhesive labels. After adhesion and connection to the burglar alarm system or other power source, the label will flash and thus warn that the burglar alarm has been connected . The flashes of the light diode, e.g. one flash per secorrd, provide, as mentioned, an enhanced preventive effect of . the function of the warning label. This applies ; in particular in dim day light or darkness where it may be difficult to see a normal warning label. Owing to the simple structure, the invention makes it possible to produce a flashing warning label which improves the preventive effect of the warning label for a burglar alarm system in a simple and inexpensive manner. The mounting of the flashing light diode with its auxiliary circuits is an extremely simple process. An embodiment of a warning label of the invention is shown in the drawing, in which fig. 1 is a front view of the label, fig. 2 is a section along the line A-A in fig. 1, fig. 3 is a rear view of the label, and fig. 4 is a section along the line B-B in fig. 3. The flashing label may consist of two layers of fusible sheets 1, fig. 2, between which a small electronic circuit 2 and a flashing light diode 3 is embedded or sandwiched. The warning text 6 is printed or glued as a double-adhesive sheet on the front side of the label. A lead 4 is connected to the burglar alarm or an external power source. In the embodiment shown, one light diode or lamp is fitted; but nothing prevents the use of several flashing light diodes or lamps. The shown and described structure may be modified in several ways within the scope of the invention. The light source might e.g. be placed on the rear side on a trans¬ parent label instead of being sandwiched between two adhered layers. It may also be adapted to edge-illuminate a label so that a pattern or text embossed in the label appears as luminous portions. Nor is the use of the invention conditional upon the label being transparent or transluscent. Another possibility is to provide the label with strips, e.g. in the form of a pattern or a text, of a material which may be caused to be fluorescent.

Claims: AMENDED CLAIMS [received by the International Bureau on 11 March 1988 (11.03.88); original claims 1 and 2 replaced by amended claim 1; claims 3-6 renumbered as 2-5 (1 page)] 1. A label for alarm systems comprising two sheet layers, c h a r a c t e r i z e d in that a light diode or lamp is embedded or sandwiched between the two layers . 2. A label according to claim 1, for mounting on -a glass pane, c h a r a c t e r i z e d in that it has an adhesive front side. 3. A label according to claim 1, for mounting on a non- transparent face, c h a r a c t e r i z e d in that it has an adhesive rear side. 4. A label according to any of the preceding claims and comprising a light diode, c h a r a c t e r i z e d in that the label is firmly connected to an integrated circuit adapted to cause the light diode to flash. 5. A label according to claims 1 and 4, c h a r a c ¬ t e r i z e d in that also the integrated circuit is embe-d-ded or sandwiched between t e two sheet layers.
