Without video amplifier, the maximum cable length from the first cam- era the last home station 100 150m (for 0.6 0.8mm wire diameter A maximum video devices may connected cable section. Because the video signal the video amplifier only routed one direction from Bus_IN Bus_OUT, all devices which emit video signal must connected Bus_IN via the Gira 2-wire bus.8 mm (A) (A) (A) (B) (A) video distributor order no. 1222 00 Technical data Ambient temperature: -25°C +70°C Port: Screw terminals Dimensions D): 27mm Installation: surface-mounted sur- face-mounted junction box - flush-mounted deep flush- mounted device box - on top-hat rail using included DRA adapter Device description The video amplifier used extend the range Gira door communica- tion systems with video function. - The video amplifier counts device. - maximum video distributors including video multiplexers can be used one system. The lengths specified this example are the maximum line lengths per section.

Connection terminals: Bus_IN Connection for the incoming video signal from door stations with video function, DCS-camera-gateways DCS-IP-gateways. With video amplifier, the maximum cable length from the first camera to the last home station 200 300m (for 0.6 mm/150 0. With video amplifier, the cable length between the door and home sta- tion can extended 100 150m maximum 300m. Example system with home stations and specification cable lengths.8 mm max. The number devices depends the number simultaneously called up home stations with video function: Home stations video per residential unit 3 Residential units 6 Home stations 18 The following rules apply: - maximum devices can connected each cable section. .

Maximum line lengths with video components from the control unit to the last device (when using the video amplifier): - 100m with 0. Cable lengths In systems with video components, the maximum total line length is 300m (distributed over several cable sections). The video signal forwarded amplified state via Bus_OUT. max. g. 100 m K 0. doing so, the line attenuation from the source the video sig- nal the input the video amplifier compensated.615 Gira electrical installation systems Video Door communication I Technical information Video amplifier Order No. The video amplifier increases the volume the incoming video signal to the maximum permissible bus volume and outputs the output the device.6mm wire diameter - 150m with 0.6 mm/150 m K 0. 100 0.
