Firefighter telephone outlet plan symbol

Plan symbol for a firefighter or emergency warden telephone outlet used for communication during an incident.

In plain English

What does Firefighter telephone outlet plan mean?

Firefighter telephone outlets, or warden intercommunication points, give two-way voice communication between floors and the fire control point. Plans draw a telephone handset mark or outlet tagged FFT, EWIS or WIP at stair landings and plant rooms.

A simple example

The circuits are monitored and often fire-rated, so the plan symbol tells the installer to use the specified fire-resistant cable. Positions follow the fire code and brigade requirements. The symbol does not show whether the outlet is a jack for a portable handset or a fixed phone.
