A checking call voice message is played for manual pickup (confirmation

Operational Call
Operational call is a call made automatically whenever a defined event happens (stuck button,
rescue end, audio error, ...). Refer to Subs.
Incoming Call
The control center can also call the
2N
®
LiftIP 2.0
number, which automatically receives every
incoming call. The incoming call is time limited and controlled like the outgoing call (extension,
identification).
The incoming call can, for example, inform a trapped person about the rescue squad arrival, etc.
Also, it helps check
2N

remotely for proper function and connection.
Useless Startup Protection
As the only purpose of
2N
®
LiftIP 2.0
is to call for help when a person gets trapped in a lift, no
call is necessary if the cabin door is open. If the lift is equipped with a door contact, connect the
contact to the
2N
®
LiftIP 2.0
CANCEL input and define a timeout for
2N
®
LiftIP 2.0
to wait after
the ALARM button is pressed until it establishes connection. Thus, if the ALARM button is pressed
by mistake, the lift arrives in a floor, the door opens and the call is canceled. Also, the minimum
button pressing time can be set to eliminate erroneous pressing of the button.
Call End (Outgoing/Incoming)
The call end (line hang-up) occurs whenever any of the below listed situations happens:
The counterparty (control center) hangs up;
The maximum call duration expires – 10 s before the expiry,
2N
®
LiftIP 2.0

“Attention, the call end is near. Press 4 to extend the call.” to allow you to extend the call.
