LABEL FOR ALARM SYSTEMS

INDICATEUR POUR SYSTEMES D'ALARME

English Abstract

A b s t r a c t
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.

Claims

The embodiments of the invention in which an
exclusive property or privilege is claimed are defined as
follows:
1. A label connectable to an alarm system
comprising:
a first sheet, having a means for mounting said
first sheet on a light transmitting surface so that a
warning sign on said label is visible through said surface;
and
a second sheet fixed to said first sheet so that
at least one light emitting diode is positioned between said
first and second sheets to project the light from the diode
through said light transmitting surface and illuminate said
label.
2. A label according to claim 1, wherein said
diode is connected to an integrated circuit which causes
said light emitting diode to flash.
3. A label according to claim 2, wherein said
integrated circuit is positioned between said first and
second sheets.
4. A label according to claim 3, wherein the
first sheet is transparent.
5. A label according to claim 3, wherein the
first sheet is translucent.
6. A label connectable to an alarm system
comprising:
at least one sheet, having a means for mounting
said first sheet: on a light transmitting surface so that a
warning sign on said label is visible through said surface;
and
- 4 -

a light emitting diode attached to said sheet to
project the light from said diode through said light
transmitting surface and illuminate said label.

A Label for Alarm Svstems
Self-adhesive labels e.g. with printed warning - ALARM -
S are known and extensively used in connection with burglar
alarms. The text on the labels may vary, but their purpose
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 panel
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 manner.
In accordance with an embodiment of the invention, a label
connectable to an alarm system is comprised of at least one
sheet, having apparatus for mounting the first sheet on a
light transmitting surface so that a warning sign on the
label is visible through the surface, and a light emitting
diode attached to the sheet to project the light from the
diode through the light transmitting surface and illuminate
the label.
When a flashing label is to be adhPred to e.g. a glass
pane, the protective paper is removed from the adhesive
front side of the panel, 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 second,provide, as mentioned, an enhanced preventiva 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.
In accordance with an embodiment of the invention, a label
connectable to an alarm system is comprised of a first
sheet, having an apparatus for mounting the first sheet on a
~ light transmitting surface so that a warning sign on the 20 label is visible through the surface, and a second sheet
fixed to the first sheet so that at least one light emitting
diode is positioned between the first and second sheets to
project the light from the diode through the light
transmitting surface and illuminate the label.
An embodiment of a warning label of the invention is shown
in the drawing, in which:
Fig. l is a front view of the label,
Fig. 2 is a section along the line A-A in Fig. l,
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
S 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 csnnected
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 edga-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.
