<Desc/Clms Page number 1> Description: SERVO-VANNE. Bouche d'aération pour' systèmes de ventilation et de oondi- tionement d'air' se fermant automatiquement en présence de gaz ou fumée, pour prévenir toute propagation via le systè- me et neutraliser ainsi les risques d'intoxication à dist- ance lors d'incendies ou d'accidents industriels. Principe de fonctionement; une grille d'aération à fermetu- re manuelle, de type et dimentions standard: A,est asservie par un petit moteur basse tension à courrant continu: B, lui - même commandé par un ensemble électronique détecteur de gaz (divers) et de fumée: C, raccordé à un sensor: D, l'ali- mentation est assurée via le secteur par' une unité à trans- EMI1.1 formateur' (220V/12V): B. Une batterie d'accumulateurs: F, garanti le bon fonctione- ment du dispositif en cas de panne de courrant. Une alarme sonore est produite par un buzzer: G. Un interrupteur manuel: H, permet la réouverture de la bou- che d'aération après une alerte. Un témoin vert: I, indique une de service suffisante au bon fonctionement. L'embase: J,, sert de boitier: <Desc / Clms Page number 1> Description: SERVO-VANNE. Air vent for 'ventilation and air conditioning systems' which closes automatically in the presence of gas or smoke, to prevent any spread via the system and thus neutralize the risks of poisoning from a distance during industrial fires or accidents. Principle of operation; a ventilation grille with manual closing, of standard type and dimensions: A, is controlled by a small low-voltage motor with direct current: B, itself controlled by an electronic assembly detecting gas (various) and smoke : C, connected to a sensor: D, the power is supplied via the sector by a unit with trans- EMI1.1 trainer '(220V / 12V): B. A storage battery: F, guarantees the correct operation of the device in the event of a power failure. An audible alarm is produced by a buzzer: G. A manual switch: H, allows the ventilation opening to be reopened after an alert. A green light: I, indicates a service sufficient for proper operation. The base: J ,, serves as a case:| Application Number | Priority Date | Filing Date | Title |
