The unit is intended for indoor installation and simplifies power management for Gira intercom systems.

Advantages

The GIRA 128800 can supply power to up to 2 door stations with a colour camera and up to 28 home stations equipped with TFT colour displays. It can activate a total of up to 15 colour cameras (combination of door stations and DCS-camera-gateways), while providing self-resetting electronic short-circuit and overload recognition for both the operating voltage and the bus connection.

How to use

Install the unit indoors according to Gira installation guidelines and connect the 2-wire bus to the door communication network. Use the AC 12 V output or the relay output to connect a door opener, depending on whether the opener uses the control unit's supply or its own power source. Program system functions and door opener times using the front-panel buttons; monitor status and fault conditions via the LED indicators.

Recommendations

For reliable operation, provide separate power supplies for colour cameras that exceed the unit's direct supply capacity and ensure installation by a qualified technician following local electrical regulations and Gira documentation.
