Connection scheme

Below are general BAS-IP lift controller connection schemes:

1 Connection to the Call buttons located on the floors, or connecting to the centralized input module responsible for calling the elevator to the floors
2 Connection to elevator buttons on lift car keypad
3 Connection directly to the elevator controller or cross equipment
4 Connection for Using the Two-Step Mode of EVRC-IP

Connection to the Call buttons located on the floors, or connecting to the centralized input module responsible for calling the elevator to the floors

This connection is used to simulate pressing the floor buttons in the Call Up/Down mode.

Connection to elevator buttons on lift car keypad

This connection is used in the Access Control Manual mode, where EVRC ports are linked to the floor buttons in the elevator cabin to simulate their pressing.

Cable length recommendation

The maximum recommended cable length between EVRC-IP and the elevator cabin buttons depends on the wire diameter and the elevator system design:

Up to 5 meters with cable of 0.41 mm diameter;
Up to 10–12 meters with thicker cable, such as 1.5 mm diameter;
Some elevator systems may support 10–20 meters or more, while others may allow only up to 5 meters.

To ensure stable operation, we recommend not exceeding 5–7 meters, unless the elevator controller explicitly supports longer button wire extensions.

This applies especially when EVRC-IP is connected in-line with elevator cabin buttons, as in Access Control Manual mode.

Connection directly to the elevator controller or cross equipment

This connection is used to interface EVRC with the elevator control system, allowing it to simulate button presses for floor calls or inside the elevator cabin as required by the selected mode.

Connection for Using the Two-Step Mode of EVRC-IP

The same cable length recommendations as in Access Control Manual mode.

Avoid exceeding 5–7 meters between EVRC-IP and the elevator buttons to ensure reliable operation.
