Fire Fighting Interc m Operati n:
When the system is operated via turning
ON the Fire Fighting Switch on the panel,
a three way communication link will be

Room Speaker & the Lift Car Speaker.
“Press to speak” button is provided on the
Panel and on the Motor Room speaker to
communicate to the other speakers.
Turning OFF the Fire Fighting switch will
turn off the communication.
Evacuati n Interc m Operati n:
When the system is operated via turning
ON the Evacuation Switch on the panel, a
speech link can be provided to allow
communication between the Master
Switching Panel and any of the outstation
speaker bo es in the system.
All calls will be registered on the Master
Switching Panel when the “Call” button is
pressed on any of the Outstations.
To answer a call, the Evacuation
Manager, simply presses the flashing
button for the corresponding outstation. At
this point a voice link will be opened.
Once the conversation has finished, the
pressing of the fully illuminated button, on
the Master Switching Panel, will now
cancel the call.
If for any reason the Evacuation Manager
wishes to speak to an outstation, he
simply presses the button corresponding
button of the outstation. A voice link will
be opened and the button will fully
illuminate.
NB: Acoustic feedback will occur when
the Lift car doors open if the Main
Switching Panel is near the Lift car's
opening. (Use a relay on the "door open"
signal to avoid feedback problems).
NB: Fire Fighting will have priority over
the Evacuation. i.e. if the evacuation
switch and fire fighting switch are turned
ON at the same time, the system will
operate as the Fire Fighting Intercom
system.
