CA 2630358

A window-attached alerting device (10) having an electronics circuit (12) that is enclosed within an alerting device enclosure (40) that includes an outer side (42) and an inner side (44). The outer side (42) is removably attached to an inner surface (62) of a windowpane (60) that is attached to a building. Since the enclosure (40) is attached to the inside of the building, the enclosure is not exposed to inclement weather or to theft. The outer side (42) of the enclosure (40) is visible through the windowpane (60) and includes indicia (52) in the form of a target (54) or the like that is positioned to encompass an electrode (22). When a person places his/her finger or hand proximate to the target (54) the electrode, in combination with the electronics circuit (12), produces an alerting device signal 31 that can be easily heard within the building.

L'invention concerne un dispositif d'avertissement (10) destiné à être fixé à une fenêtre, comprenant un circuit électronique (12) contenu dans un boîtier (40) possédant un côté extérieur (42) et un côté intérieur (44). Le côté extérieur (42) est fixé de manière amovible à une surface intérieure (62) d'un carreau de vitre (60) d'un bâtiment. Etant donné que le boîtier (40) est fixé à l'intérieur du bâtiment, il n'est pas exposé aux intempéries ou au vol. Le côté extérieur (42) du boîtier (40) est visible à travers le carreau de vitre (60) et comprend des caractères (52) formant une cible (54) ou analogue disposée de manière à entourer une électrode (22). Lorsqu'une personne place son doigt ou sa main à proximité de la cible (54) et, par conséquent, de l'électrode, le circuit électronique (12) déclenche un signal d'avertissement (31) qui peut être facilement entendu à l'intérieur du bâtiment.
