The Fireman audio unit improves the fire fighting operations by setting up top priority
calls to the cabin audio unit in one and the same lift shaft. If any of the machine room
audio units is configured as the control centre (intercom), you can join in the Fireman
call.
Install the Fireman audio unit in a dedicated space that can be easily accessed by
firemen.
The Fireman call has the highest priority, suspending all the other calls (refer to
). It is connected with the cabin audio unit in one and the same
shaft.
Press the button to set up the call. The call duration is infinite. Repress the button to
stop the call.
The Fireman call setup is signalled by the Fireman audio unit LED (mounted on the
electronics board or carried externally from connector 8).
If the control-centre configured machine room audio unit is used, the Fireman call is
signalled by a green LED flashing on the audio unit. Push
(for longer than 2 s) on
the audio unit keypad to join in the call. Push
(for longer than 2 s) on the audio
unit keypad to leave the call without terminating it.
