Coax
Which kind of cable is suitable for coax system?
- It’s necessary RG59 type up to 300 mt or different but respecting 75 Ohm of impedance (not suitable satellite cable).
What can happen when using no coax cable or cable with different impedance?
- The picture can appear crummy and without contrast.
Is it possible to install a monitor at 900 mt far away from camera?
- Yes, by using a video amplifier sch. 1840/250 next to the monitor.
How many video distributors 1794/4 can be powered on a system?
- Up to 10, for furthers it’s necessary a supplementary power supply sch. 789/2 for every 20 distributors, providing 2 additional wires on the riser.
How many video house phone can ring together with power supply 789/5B?
- Up to 4 video house phones.
Is it possible to realize an implantation with a mix of black and white and colour video house phone?

- The unused video outputs must not be closed by resistor. Output 5 is dedicated for other distributors, when connected remove 75 Ohm jumper JP1.
Is it possible to activate supplementary services in the same time of external call?
- Yes, by using call repeater relay sch. 788/52. The relay is equipped with 2 exchange contacts able to drive circuits with voltages not exceeding 24 V and maximum currents of 5A.
Is there a table support for video house phone?
- Yes, kit 1702/92 specific for Atlantico.
Is it possible to utilize video distributor for TV antenna in alternative of 1794/4?
- Not suggest able, because video signal could work in low frequency, usually by a value of 1 Vpp.
Is video house phone Atlantico suitable both in coaxial and 5-wires system?
- Yes, it is, using dedicated bracket 1202/90 in coaxial implantation and bracket 1202/955 in 5 wires ones.
Is it possible to regulate call volume on Atlantico?
