Specifications

In cases where the call procedure is initiated with a pulse,
and no presence contact is desired, then an input assigned
as a ‘reset input’ can terminate this procedure and return
the software to the stand-by mode.
A ‘reset pulse’ can also be given to one or more call
inputs. If a contact input assigned to ‘handle a relay’ is
activated,a pre-programmed relay on one of the
couplerheads will either be activated or de-activated
depending on the programming.
Call Rerouting
All of the assigned contact inputs can be routed to one
specific pager.Rerouting can be initiated by the keyboard
of the PC, by the real-time clock in the PC, or by one or
more of the contact inputs of the multi-purpose
couplerheads.
Relay Output
Two relay outputs are available on each couplerhead.
Both can be activated by either of the following:
• by a contact input on the coupler heads.
• by a defined paging call string on the data lines.
• directly from the keyboard of the PC.
• or if communication is lost,between the PC and
the couplerhead.
Contact Monitoring
The activity of the contacts can be monitored while the
software program is running. The PC monitor will
display which call is being transmitted because of an
activated contact input. Calls can also be blocked while
monitoring the contacts - this function is used for
installation purposes.
Communication Monitoring
The software may be programmed to constantly check
whether communication with the assigned couplerheads
is still available. In situations where communication with
a couplerhead is lost for more than ten seconds, the
alphadesk will transmit a preprogrammed call to a
receiver. The information of this call can include the
number of the couplerheads involved. Such a call will be
repeated every 10 seconds until communication with this
head is restored, or until the scrolling of the couplerhead
is terminated by using the MPC editor.

(3)A third call function,identical to Call (2) but with the
difference that an alarm call is transmitted to a third
(freely programmable) address - for example a group
call- if no reaction was given to the assistance call.
This call also contains the same information as the
original call.
The bleep-pattern of this call is again freely
programmable. This alarm call will also be repeated a
maximum number of times or until the presence
contact is activated. If the call contact is again
activated while the presence input is still active, then
either the assistance call or the alarm call will be
transmitted, depending on the type of call the
presence input was activated for.
(4)The fourth call function, identical to call (3), has the
possibility of activating an alarm relay if no reaction is
given to the alarm call within a pre-programmed time
limit.
Situation 1 is defined as a ‘Call’, while situations 2,3 and 4
are each defined as a ‘call cycle’. For ‘call cycles’a presence
input is required and a reset input may be required for a
‘call’, if the call is initiated by a pulse.
A maximum of 32 ‘call cycles’, such as assistance calls,
alarm calls and alarm relays are freely programmable.
This means that each couplerhead may be given its own
assistance call, alarm call and alarm relay.
Each repeat time and number of repeats can be
programmed independent from each other. A delay time
can also be programmed to delay the first call for a
duration of 0 to 255 seconds after the contact input has
been activated.If a reset is given within the delay time,
the call will not be transmitted.
When activated, a contact assigned as a ‘Presence input’
will provide a presence command to one or more call
contacts.When the contact is activated - activated by
pushing the call contact once more - it will initiate the
assistance call, alarm call or the alarm relay. In addition
presence can also be reported on the assistance call,alarm
call, or the alarm relay by activating once again the
presence contact. If the presence contact is de-activated,
while none of the assigned calls is transmitted, the
software returns to the stand-by mode of the relevant call
input.
