Compatibility of systems from different series
Systems DET AC Plus Slave of the old series (Part No. 7338.320) can as a general
rule be connected to active extinguishing systems DET-AC III Master of the new
series (Part No. 7338.121). In the same way, systems DET-AC III Slave of the new
series (Part No. 7338.321) can as a general rule be connected to active
extinguishing systems DET AC Plus Master of the old series (Part No. 7338.120).
The systems are fully functional. However, not all messages are transmitted and
certain functions cannot be performed (e.g. Maintenance Program, external
tank, ...).

Networking systems
Up to five systems (active extinguishing system DET-AC III Master or EFD III with
DET-AC III Slave) can be networked with each other via a bus system to protect
several switch cabinets. One data line and one supply line respectively must be laid
