Details
The 4000 Series audio door entry kits benefit from advanced features such as electronic call tone generation and lock release relay included within the door panel. This reduces the cable requirements between the handset(s) and the door panel to only 4 (3+1) connections. For this reason larger cable distances using small cores sizes can be achieved between door panel and telephones.
The kits are supplied complete with the door station including the digital code lock, power supply and all handsets depending on the number of call buttons.
