DOOR PHONE - VIDEO DOOR PHONE SYSTEMS: Installation Diagrams

Traditional call systems are suitable for making new systems with call

signal to a dedicated buzzer ﬁ tted inside the door phone.

This type of door phone is suitable for replacing 1030, 930 and

730 model door phone in existing systems and for making intercom

systems.

“1+1” wire systems

“1+1” wires systems are available with electronic call option only.

These systems are characterised by simple wiring with only 2 wires for

each user.

They are suitable for making new installations and are most appreciated

for use in old buildings to replace an existing call only system (button

and bell). The existing service can be transformed into a door phone

system without adding wires to the column or in the apartments.

In this systems, only the called door phone can pick up the conversation

with the visitor (no other users can cut into the call in progress) and

open the electrical door lock.
