from the second group (parameter 2). The next press of the same
button again selects the number from the first group, etc..……
If the button is pressed after the line has been opened (but before the
call is answered), the unit will hang up for the period given by parameter 54, lift
up the line and dial the other group number.
The relay can be controlled by pressing the buttons in the combination
that is set in the preprogrammed code (parameters 32-34). The time between
presses must not be bigger than that set in parameter 53. The unit will lift up
and close the corresponding relay or the period given by parameter 36 . Then it
will hang up.
3.3 Telephone Caller
A Telephone Caller is a person that is in phone connection with
SlimDoorPhone.
3.3.1 Outgoing call
An “outgoing” call is a call from the unit (i.e. when a visitor presses a
button). Once the visitor has pressed a button a telephone will ring. On
answering the telephone, you will be able to converse with the visitor. 10
seconds before the maximum call duration (parameter 52) the unit will emit a
tone to warn that the call will end. The call may be extended by pressing the
key as set in parameter 42. A code may be dialled to close the relay
(parameter 35), releasing the lock. Hanging up the telephone will end the call,
as will the busy tone from the PBX.
3.3.2 Incoming call
An incoming call is a call to the unit. After dialling the PBX extension number to
which the unit is connected, the unit will ring for the set number of rings
(parameter 51), the unit will lift up and it is possible to speak. The possibilities
are the same as with outgoing call (Chapter 3.3.1). It is also possible to switch
between Day and Night service.
•
If, within the first 10 seconds, the service password is entered, the unit
will switch to programming mode and voice communication will cease.
•
During an incoming call it is possible to restrict relay control (parameter
37). This can be useful in some special applications.
