Check Call
A check call is an automatically made outgoing call whose purpose is to check the
function of the
system. Unlike common outgoing calls, check calls have
2N Lift1

different announcements ("Check call") and use different phone number sets.
Typically, check calls are received automatically if the control centre is equipped with
the
software. All you need to operate the program is a standard PC with a
2N Lift8
®
VoIP account.

answers the line after two rings (or as configured) and sends a sound signal. The
purpose is to provide the person trapped in the lift with necessary information (about
rescue, for example) and check remotely whether
2N Lift1
®
is connected and works
properly.
Useless Startup Protection
As the only purpose of
is to call help in case of emergency, any call made
2N Lift1

when the door is open is considered useless. Hence, connect the door contact if
available to the
CANCEL input and program a connection establishing delay

after ALARM pressing. In this case, if the ALARM button is pressed by mistake, the lift
arrives in the next floor and the door opens thus cancelling the call. Or, you can set the
minimum button pressing time to prevent unintentional ALARM pressing.
Note
The purpose of this section is to help technically trained persons get
insight into the processes running in
during operation. This
2N Lift1
®
information is unnecessary for common
2N Lift1

installations.
