t4 – time activation 2 of relay (Parameter 372)
t5 – time between pulses 1 of relay (Parameter 302)
4.4. Telephone Caller
A Telephone Caller is a person that is in phone connection with Link Ana iDP.
4.4.1. 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. Pressing the key as set in parameter 42 may extend the call. A code may be dialed
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.
4.4.2. Incoming call
An incoming call is a call to the unit. After dialing 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 (#0000), the unit will switch to
•
programming mode and voice communication will cease.
Second exception is when DIP1 is switch to position ("SERVIS"). Then you enter in programming
•
mode directly without dialing service password.
During an incoming call it is possible to restrict relay control. This can be useful in some special
•
applications.
5. Parameter programming
5.1 Programming from a phone by DTMF
The Link Ana iDP may be set to programming mode in two ways:
by password : dial the unit's number (either extension number, if connected to a PBX or
•
telephone
number, if connected to a PSTN line). The unit will answer (you will hear the Pick up
line tone – see Chapter 3.1). Within 10 seconds dial # xxxx, where xxxx is the password for
entry to programming and, if OK, the registration tone for programming mode will sound, and
afterwards the Programming tone is heard.
By "SERVICE" switch – dial the unit in the same way as in 1, but when the SERVICE switch is
•
connected, the unit will automatically enter programming mode. You will hear the call connection
confirmation tone; the confirmation tone for programming mode and afterwards the
Programming tone is heard.
5.1.1 Parameter programming
The initial state for programming is signaled by the programming confirmation tone. The unit will always
revert to this state after 5 seconds of inactivity, even if you have started to program a parameter.
When programming, there are two types of parameters. The majority are parameters with a fixed
length. The parameter is always saved immediately and is confirmed by Parameter Confirmation tone.
Parameters with variable length (parameters 1,2,32,33,34) are saved after the inactivity period
expires (5 sec). However, a variable length parameter will be saved immediately when maximum
