12 OPERATION
This section continues with a description of the alarm management mode by
standard telephone users. For information about alarm management with
automatic protocols (Esse-ti or Ademco Contact ID) please refer to the
corresponding documentation. The following codes (“Acknowledgement”,
“Handsfree”, “Exclusion” and “End”) are factory-set codes. In case of re-
programming, you must use the new codes. The “Exclusion” and “End” codes
are also used in the Ademco Contact ID protocol.
Call cycles
Upon an alarm or during the automatic test, the device generates a sequence of
calls to the numbers programmed and associated with the event. The device
makes two consecutive calls to each number. Each call lasts up to 1 minute.
After calling the last number, the device starts a new cycle of calls, supposed
no one answered and gave HelpyL300 the proper codes, starting from the first
number.
The number of call cycles can be programmed from 1 to 10 for technological
alarms, diagnostics, remaining credit and automatic test call (by default it is set
at 5). In order for the calls to be held valid and accepted by Helpy L300, the
called party must not be found busy.
A special feature of the technological alarms, diagnostics and the automatic test
call is the "CLI" – mode. By routing the calls associated with different alarms
to different telephone lines, the call center manages to discriminate which type
of alarm has been received thanks to the information contained in the CLI
(caller line identification). In this way, it is not required to establish a
connection in order to determine the event, you simply need to be sure that at
least one call has been forwarded to a free telephone number. By setting a call
center working under “CLI” mode as the destination of an alarm call, the Helpy
L300 will carry out as many call cycles to the programmed numbers until it
succeeds to reach a free telephone number. At this point, the calls will end
without any further need to be answered.
As far as the emergency-call alarms are concerned, the number of call cycles is
unlimited.
