A good electrical and security installation has never been taken into account in the construction of historic buildings. Since such buildings have great historical and cultural value, a good fire detection system is often required. However, the aim is to affect the appearance of the rooms as little as possible, so that the fire detection system should be installed as invisible as possible. By using very small capillary points which, because of the active suction can often be mounted in less visible places, Stratos aspirating systems can be used almost invisibly.
Another technique that is often used in historic buildings is that of beam detection. This technique uses a transmitter / receiver combination that functions with an infrared signal. When the infrared beam is disturbed by smoke, this can lead to a fire alarm. This technique is applicable when no obstructions are or cannot be present in the room.
