More and more operators are calling for the installation of automatic extinguishing systems to protect passengers and investments. The aim is to extinguish a fire in its development. These systems are becoming increasingly important in long and short haul rail travel as well as underground train networks.
Stand-alone extinguishing systems are not activated via a fire detection and alarm panel, but are a combination of an extinguishing system with an autonomous detection unit which activates the extinguishing system in the event of a fire. As a general rule, they employ heat detectors which trigger an extinguishing system directly once a predefined temperature is reached. These systems are equipped with monitoring (changeover) contacts, which can then be used to transmit the activation of this type of system to a detection and alarm panel or to the train bus.
The advantage: Stand-alone systems do not require any additional detection or power supply, and are ideal for small technical areas.
