The remote signals involve faxes, SMS messages, calls to the service centre and activation of the relay, and are effected only
when at least one alarm remains active for a time greater than the delay set for the corresponding category.

The fax is transmitted only when the remote signalling condition exists and the following 2 conditions are satisfied:
at least ½ hour has elapsed since the transmission of the previous fax
at least 1 minute has elapsed without remote-signal alarms being activated, or alternatively there are more than 32 active
This type of filtering prevents repeated faxes being sent containing “similar” information.
The following is the format of the fax sent in response to one or more alarm condition:

The list of alarms is compiled in reverse chronological order, from the more recent to the oldest, copying from the PlantWatch
internal log only the start alarm events, while the signal-only events and end alarm events are ignored, except for the PlantWatch
reset.
The alarms that are still active at the moment the fax is transmitted are printed preceded by the symbol <!>, while those which,
due to their seriousness or duration over the set delay time, have brought about the sending of the fax, that is, have become
remote-signal alarms, are also preceded by the symbol <*>, and this symbol is followed by a number that indicates the duration
of the alarm in hours and minutes; if the alarm has been or is active for more than 18 hours, the indication “>18” is displayed.
If after the activation of the remote signalling condition the alarms that caused such condition are over, the fax will still be sent,
without indicating any active alarms.
A maximum list of 35 alarms is sent, to leave space for the report of the variable values read at the moment the fax is sent.
The heading of the fax includes the date and time of transmission, the name of the installation, the installation code and the
telephone number of the fax recipient. The installation code is the number used by the data processing centre (supervisor) to
identify the PlantWatch system that has performed the call.
