  • Process for the automatic reporting and extinguishing of fires
    Patent number: 4005754
    Abstract: A process for the automatic reporting and extinguishing of fires and an automatic fire reporting and extinguishing system capable of performing such process are provided. The process uses at least two different types of fire reporting devices and requires a signal from each type of device in order to respond by releasing extinguishing agent. This requirement eliminates many false alarms and unnecessary releasing of extinguishing agent. According to the process extinguishing agent is released in a predetermined quantity and then a check is made to determine whether the fire has been extinguished. If the fire is not extinguished, another quantity of extinguishing agent, equal to the first, is released. Succeeding quantities of extinguishing agent are released until the fire is extinguished or the extinguishing agent is spent.
