Title (EN) A DEVICE AND SYSTEM PROVIDING INCREASED OPERATIONAL SAFETY OF AN INSTRUMENTATION LOOP SYSTEM
(FR) DISPOSITIF ET SYSTÈME FOURNISSANT UNE PLUS GRANDE SÉCURITÉ DE FONCTIONNEMENT D'UN SYSTÈME DE BOUCLE D'INSTRUMENTATION
Abstract:
(EN) The present invention provides redundancy in instrumentation loop systems, such as smoke and fire detection systems without any duplication of safety devices, instrument devices, smoke detectors or controllers. Redundant loop devices for control of loop access according to the present invention provide interface for physical communication sections of the loop and a communication protocol for the loop system.
(FR) La présente invention procure une redondance dans des systèmes de boucle d'instrumentation, tels que des systèmes de détection de fumée et d'incendie sans avoir à dupliquer les dispositifs de sécurité, les dispositifs d'instrumentation, les détecteurs de fumée ou les contrôleurs. Des dispositifs de boucle redondants destinés à commander l'accès de boucle selon la présente invention fournissent une interface pour les sections communications physiques de la boucle et un protocole de communication pour le système de boucle.
