Title
(EN) HEAT-ACTIVATED ALARM AND RESPONSE SYSTEM
(FR) SYSTÈME D’ALARME ET DE RÉPONSE ACTIVÉ PAR LA CHALEUR
Abstract
(EN) A heat-activated fire-suppression system is provided. The system can include one or modules installed in an exterior panel of a building. The one or more modules can include a shape memory alloy wire that deforms upon heating to cause the module to release a pressurized substance. The system can include an alarm module that emits an auditory alarm. The system can include a fire-suppression module that releases a fire-suppressing substance upon the shape memory wire deforming in response to heating.
(FR) L’invention concerne un système d’extinction de feu activé par la chaleur. Le système peut inclure un ou plusieurs modules installés dans un panneau extérieur d’un bâtiment. Le ou les modules peuvent inclure un fil d’alliage à mémoire de forme qui se déforme en chauffant pour amener le module à libérer une substance pressurisée. Le système peut inclure un module d’alarme qui émet une alarme sonore. Le système peut inclure un module d’extinction de feu qui libère une substance d’extinction de feu lorsque le fil à mémoire de forme se déforme en réponse à son chauffage.
