## Symbol convention

Convention: IEC
Form: Telephone set
IEC 60617 installation-plan style (architectural and topographical installation symbols); independently drawn, not certified IEC geometry or a database identifier.

Symbol for a telephone instrument, drawn as a handset shape, used on communication layouts and schematics.

## In plain English

### What does Telephone set mean?

The telephone set symbol shows the instrument itself, usually as a stylised handset over a base or a circle with a handset. It appears on communication system diagrams, lift and emergency phone schematics and on plans where a fixed phone is supplied.

### A simple example

Where a phone is provided as part of a system, such as a lift car phone, help point or emergency phone, the symbol distinguishes the supplied device from a simple outlet. The plan then tags the device type. The symbol does not tell you whether the instrument is analogue, IP or hands-free.

### What the drawings help you do

Check whether the instrument is supplied or only the outlet. Read the device type tag. A telephone outlet is the termination; the telephone set symbol is the instrument.

### This particular reference

Symbol for a telephone instrument, drawn as a handset shape, used on communication layouts and schematics. A telephone outlet is the termination; the telephone set symbol is the instrument.
