SMS RECIPIENT PRIORITIES

Method of priority
By time delay.
Upon detection of an event,
the Silent Sentry will
immediately send the
relevant message to all
priority 1 recipients. If no
acknowledgment is
received within the user
specified time, then the
Silent Sentry will send the
same message to all
priority 2 recipients.
If still no acknowledgement
is received, then the
message is sent to all
priority 3 recipients.
HOLD OFF TIME PROTECTION
To ensure that an errant process alarm does not send
SMS messages too often, it is possible to set a Hold Off
time for all messages. Once a message has been sent to
all recipients, the message will not be sent again for at
least the duration set in the Hold off time setting.
SMS ALARM ACKNOWLEDGMENT
Method
All outstanding Alarms in
the Silent Sentry can be
acknowledged by sending
an SMS to the Silent Sentry
with the words “Ack” or
“Yes” in the message.
MAXIMUM SMS MESSAGES PER HOUR
As further protection against an abnormally high SMS bill
for any reason, the Silent Sentry can be set to only send
up to a maximum number SMS messages per hour. This
guarantees the maximum size of your SMS bill regardless
of the status of your equipment being monitored.
DAILY SMS UPDATE
The Silent Sentry can be configured to send a daily fixed
message at a specified time of the day. This message
ensures that the system is still alive, even in the absence
of any alarm messages needing to be sent.
The recipients of this message can be individually
selected.
