GEZE Interface module IO 420

The new GEZE Interface module IO 420 allows GEZE products in the fields of automatic door systems, window technology and RWA (smoke and heat extraction) as well as safety technology to be integrated into buildings via the BACnet communication standard.

IO 420 is consequently suitable for the fast, simple and standardised BACnet integration into building management systems.
