The 1131 supports both. If your old system used a mechanical "buzz," you wire to terminal . If it’s a modern melodic tone, use The "Jumper":
Some versions have a jumper to split or join the ground (Terminals 6 and 10). If the door lock doesn't trigger, check if this bridge is needed. Volume Adjustment:
There are often small potentiometers inside to balance the "sidetone" (feedback) so you don't hear your own voice too loudly. 📂 Manual Access You can find the official technical PDF on the Urmet Australia support pages. Search specifically for the "1131/1 Universal Door Phone Manual"

System Type: This handset is designed for Electronic Call systems. It is not directly compatible with older buzzer-call systems unless specifically adapted.
Wire Identification: In older buildings, wire colors may not follow a standard pattern. If wires are not labeled, you may need a multimeter or professional assistance to identify the "Common" and "Call" lines.
Replacement: If the existing handset is missing, you can often find wiring diagrams for your specific building system on professional sites like Intercoms R Us.
Universal Alternatives: If the 1131 is unavailable, the Urmet 1130/16 is a common "Universal" replacement that can be configured for various systems, though it requires specific jumper settings. Basic Operation
Answering: Lift the handset to establish two-way communication.
Door Release: Press the dedicated "Key" button while the handset is off the hook to unlock the door.
Ending Call: Replace the handset on the cradle to terminate the connection.
