User manual for the ABB-Welcome Telephone Gateway (models 83350-500 / 83350-515) — connects a telephone system to an ABB-Welcome door communication system so that connected telephones act as audio indoor stations.
Electric voltage! Risk of death and fire due to electric voltage of 230 V.
The Telephone Gateway is part of the ABB-Welcome door communication system and works exclusively with components from that system. It connects to a telephone system as an analogue subscriber, allowing regular telephones to receive and answer door calls.
| No. | Function |
|---|---|
| 1 | Operation status of connection to PBX (connected/idle/ringing) |
| 2 | Operation status of Welcome bus (ready/receiving data/reset in progress) |
| 3 | USB port for software update (factory use only) |
| 4 | Terminal resistor switch — OFF for pure audio installs, ON for video/mixed installs on the last device of a branch |
| 5 | Long-press 3s to reset to factory defaults (both LEDs flash) |
Install only if you have the necessary electrical engineering knowledge — incorrect installation can endanger life and cause serious property damage. Follow the "five safety rules" (DIN VDE 0105, EN 50110): disconnect the power, secure against reconnection, ensure there is no voltage, connect to earth, cover/barricade adjacent live parts. Use suitable PPE and only suitable tools/measuring devices.
The device must only be installed on mounting rails per DIN EN 50022.
Configure your telephone system so the Telephone Gateway cannot be directly called from an external telephone, to prevent unauthorized access by intruders. If external access is required, activate the Indoor Station PIN.
