An aircraft factory needs to keep unauthorised people out during normal operations. In an emergency, employees need a safe way out and first responders need a way in. At Leipzig/Halle Airport in eastern Germany, Bosch Building Technologies brought both requirements into a single security system for Deutsche Aircraft’s new production site.

When a fire alarm sounds, the first question is where it came from. Security staff need to know which areas are affected, how to warn the people inside and how emergency crews can reach them. At the Deutsche Aircraft site, the project therefore covers not only fire detection and voice alarms, but also equipment along escape and rescue routes and emergency key safes. The safes are intended to give firefighters and other responders access to the keys they need without having to wait for someone to unlock the affected areas.

One site, different rules for entry

A routine visitor appointment in the administration building calls for different checks from a visit to the hangar. The logistics centre presents another challenge. Goods and deliveries need to move through the site without giving drivers or other visitors access to unrelated production areas. Bosch designed the access controls around these different security zones. At sensitive entry points, controlled entrances are intended to prevent tailgating, where an unauthorised person follows someone with permission through a door. Intercoms connect entrances and restricted areas with the security control room.

What the control room can see – and what staff must decide

The Building Integration System 360 (BIS 360) brings together information from fire and intruder alarms, access control, video surveillance and voice alarm systems. Instead of checking each system separately, operators can assess the available information together. An alarm and a camera feed, however, do not tell staff which action should take priority. That still depends on clear responsibilities and rehearsed procedures. The project announcement does not say how the site tests these procedures in emergency drills or what fallback arrangements are in place if the central platform fails.

The line has opened. Full production is still ahead.

Deutsche Aircraft officially opened the final assembly line on 29 September 2026. The opening marked a step towards series production, not the achievement of the plant’s designed annual capacity. Development, flight testing and certification remain in Oberpfaffenhofen, near Munich. Leipzig/Halle will handle final assembly, prepare the aircraft for flight and deliver them to customers. The security system will have to support the site as those operations expand and working routines change.
