About readings, alarms & Alarm Dialing:
Like most remote controls, the Sicon-8 takes reference readings, particularly when it is first powered on,
after a phone call or when it switches from local to remote mode. Reference readings are taken 1 minute
after these events and are used to establish the current configuration of meter and status values. For
instance, let’s say you decide to turn off your transmitter for any reason. When you call in and turn off the
transmitter, several readings fall below the action or critical alarm threshold but, because the Sicon-8
establishes new references, it recognizes that the transmitter has been intentionally turned off and so
does not set any alarms. When the Sicon-8 is first powered up it waits five minutes before taking its first
reference readings. Similarly, it waits briefly after a phone call is terminated, or after a timed event,
before establishing new reference readings. This is to give whatever the Sicon-8 is monitoring a chance
to stabilize. If a reading is above or below the alarm threshold but returns to a “non-alarm” condition at
any time, the Sicon-8 will use this new reading to re-establish the alarms. If the alarm condition then re-
occurs, the Sicon-8 will set the appropriate alarm and take whatever actions you have programmed.
If an action alarm and a critical (dial-out) alarm occur simultaneously, the Sicon-8 will not attempt to
automatically correct the action alarm condition but instead will only detect the critical alarm & initiate the
appropriate outbound call. If two action alarms occur simultaneously, the Sicon-8 will attempt to correct
the lowest numbered alarm first, then the higher number, if it still exists. Also, if any new alarm occurs
while the Sicon-8 is attempting a corrective action, it will stop the action, but will not attempt to initiate a
dial-out unless one of the new alarms is a critical alarm. Any new alarm, either action or critical, is placed
on the new stack for review at the next inbound call.
By default, out of tolerance conditions must exist for at least 30 secs. before the Sicon-8 will set an alarm.
93 – Jump to alarm stack at next un-played alarm - Similar to 92 above, this command lets you listen
to any alarms that have not been heard. If no unread alarms remain, the Sicon-8 will say “no more
alarms” & leave you in the MAIN menu. If you wish to return to the channel menu, enter the channel
number you wish to select. All functions behave exactly as in 92 above.
94 – Remote/Local mode toggle - If remote toggling is enabled in the system setup menu, you can
enter your special remote toggle password here twice in a row followed by the # key, each time, to
toggle between remote & local mode. If you successfully enter the password, the Sicon-8 will beep
continuously for 15 seconds before switching from local to remote mode. While this function can be
used to put the Sicon-8 back into remote mode if it has been accidentally left in the local position,
only a senior administrator that has personal knowledge that there is no one at the remote site
should ever make the decision to enable the remote mode. The special password for this function
should always be changed from the default and never given out to anyone other than responsible
senior management. You must have administrator access to operate this function.
95 – Audio monitor - turns on the audio input and feeds it down the phone line for 15 seconds. If
audio control is disabled (audio input is normally muted), then this will unmute the audio input for 15
seconds, or until a DTMF tone is entered by the user. If audio control is enabled, this simply toggles
the audio mute line. The user should exercise caution in this case because if they are controlling the
Sicon through the audio input (or with the cell-phone interface), then executing this command will
mute the input, preventing them from being able to further control the Sicon.
96 – Report Firmware Version
97 – Logout previous user - Lets you login with a different password. You can use this to increase
or decrease the current access level of the Sicon-8.
97 Logoff – does not hang up but allows for new logon ata different access level.
