<p>The invention relates to a gas detector device which goes beyond the services offered by conventional gas detectors, by allowing the issuing of graphical information relating to events and operations performed by the device while simultaneously emitting said information in parallel in the form of voice messages. In addition, the device includes two physical outputs for controlling external devices, such as the electrically operated valve for closing the gas supply, and for connecting same to a home-automation system.</p> |
