Monitorización a distancia de un sistema de extinción de incendios

A fire suppression system has a tank unit (40, 42, 44, 46). A tank body has a first port and an interior for storing at least one of fire suppressant and driver gas. A discharge assembly is mounted to the first port and has a discharge valve (50, 52) and a first monitoring switch or sensor (230 240) having a normally closed output (532) and a normally open output (534). A first monitoring system (100) is coupled to one of the normally closed output and the normally open output. A second monitoring system (340) is coupled to the other of the normally closed output and the normally open output.
