Power supply GIRA 128800 for GIRA intercom systems, white

Power supply GIRA 128800 is a control device for supplying power to audio and video components of the Gira door communication bus. Housed in a white enclosure, it provides reverse-polarity protected and short-circuit-proof 2-wire bus power required when using video components such as colour cameras and TFT colour displays. 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. Front-panel buttons allow system and door opener programming and LED indicators show operation status, overload, system programming and door opener programming.

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.
