GIRA Video amplifier 122200

GIRA video amplifier

The video amplifier serves to extend the range in GIRA door communication systems with video function. He lifts the level of the incoming video signal on the maximum permitted bus level and outputs it at the output. Thus, the line damping is compensated for from the source of the video signal to the receipt of the video amplifier.

Through the combination housing, three types of assembly are possible

• wall assembled (in a standard branch jar).
• Built-in (in a device can).
• as a regian (with the enclosed reg adapter).

Notes

• With the video amplifier, the maximum line length between the door and home station can be expanded from 100 to 300 m.
• When commissioning, no further configuration is necessary, since the video amplifier automatically adapts to the existing line network.
