During the 1970s, the first fire detection systems were installed in the wings of the palace. Fire guards specially hired by Burghauptmannschaft patrol the imperial palace day and night. After the fire in and reconstruction of the Redouten hall wing, the Vienna Imperial Palace received its own site, extinguishing, and reconnaissance operation.
The number of fire detection systems has now gone up to 23. From six detector groups to large systems with several hundred detector groups (including optical smoke detectors, heat detectors, VESTA detectors to linear detectors and, of course, pushbutton alarms). They still keep the historic look in mind.
The six gas extinguishing systems are certainly a highlight; they serve as defensive fire protection in the different archives and in the internal memory and server rooms. A sprinkler system was installed in the newly built congress centre. The entire Palace premises have 27 surface hydrants and more than 400 wall hydrants. The number of different fire extinguishers amounts to more than 1000. Fire zones and fire doors were installed in the historical buildings, as well as smoke ventilation systems in the stairwells.
The fireproofing updates and the continuous improvement of the fire protection measures on the premises of the imperial palace allow for intervention as early as during the emergence stage of fires.
