Outre un interrupteur thermique (12) qui interrompt l'alimentation en courant de l'entraînement (10) en cas de température de fusion, le dispositif d'entraînement (1) comporte en outre un capteur de température (13) pour mesurer la valeur de la température de l'air (T), un capteur de gaz (14) pour mesurer la teneur (G) en gaz d'incendie de l'air et un module de commutation (15) qui interrompt l'alimentation en courant en fonction de la valeur de température de l'air (T) et de la teneur (G) en gaz d'incendie de l'air. Le clapet de protection anti-feu peut ainsi, en cas d'incendie, être amené dans une position de sécurité non seulement en cas de température plus élevée dans la région de l'interrupteur thermique (12) mais déjà en cas de développement de gaz ou de fumées provoqué par l'incendie.
