6. OPERATING MODES
The system has the label holder combined with the button. When a visitor presses the button, the system make a
call on a PBX extension associated with the pressed button.
The numbers that are called may differ depending on the operating mode in which the system is programmed, Day
- Night mode / Group mode, set by parameter 118.
In the case of keyboard expansion, are valid the same informations as stated for the button on the base system
while the keyboard allows to dial the desired number, or to handle additional functions described later.
If is used the keyboard in Speed Dial mode, the descriptions of the operating modes listed below are valid only for
the numbers associated with the Speed Dial service.
Finally, there are three inputs for acquiring external contacts and the associated services are described later in this
manual.
6.1.
DAY / NIGHT Mode
In the Day mode will be called the number associated with the pressed button (definite in the parameter 110). In
Night mode will be called the number associated with the pressed button (definite in the parameter 114). At the
press of the button the system makes the call only once irrespective of the result. The visitor hears signalings of
ongoing call preceded by a voice message, when enabled.
If the visitor presses the button again while the call is in progress, the system stops the call and returns to standby
mode. In systems with the keyboard expansion, to stop the call, it is necessary to press the star key (*).
To put the system in Day mode, the operator must submit to the system the command entered in parameter 121.
To activate the Night mode, the operator must send the command entered in parameter 122. The system reply
playing two beeps to confirm the activation of the Day mode and five confirmation beeps for the Night mode.
It should be noted here that following a reset of the internal parameters of the system, the system restores the Day
mode. The active mode is stored in the system also when system is powered off and then when it reactivate itself,
its active mode will be restored (if the phone line is disconnected and then reconnected for example).
6.2.
DAY / NIGHT mode with call repetition to the same number
To activate this mode should be set up properly its parameter (parameter 118). The operation is similar to that of
the above described mode with in addition the possibility to perform a cycle of call attempts in order to increase the
possibilities of handling the call with a positive outcome. The call is considered successful when the operator dials
the code specified in parameter 123. In all other cases (busy, free, no answer, answer without send the code...) the
system waits for the time specified in parameter 155 after that make a new call attempt to the same number until
the end of the number of call attempts set in parameter 151 is reached.
Pressing the button again during the call cycle has no effect. The visitor will not be able to listen to the performance
of the call until the operator has not entered the code to enable communication.
The operator that receive the call will hear the system tones as a call alert by the visitor. The system returns to
standby at the end of the notice cycles or when the operator (after he has entered the correct code) closes the
conversation with the visitor.
6.3.
GROUP Mode, cyclic calls
To activate this mode should be set up properly its parameter (parameter 118).
For each button it is possible to associate two contact numbers, normally used in the Day / Night mode described
above. When the system is instead set to operate in the Group mode, the pressure of the button causes the system
to begin a cycle of calls to both numbers associated with each individual button and a third number defined in the
parameter 220.
The cycle is interrupted only when the operator that receive the call type the correct code set in parameter 123.
This mode is similar as the Day / Night mode with calls repeat with the difference that each cycle of calls is carried
out on three different numbers.
