Operation
1. When the water level goes below 1 meter (39 inches), the
alarm will trigger.
2. The local Spider will send a special message to the remote
Spider requesting that the remote Spider
’
s CONTROL 3 be
turned ON.
NOTE: The local Spider does not send
‘
On rem3
’
; rather, it
sends a specially coded command containing its own time,
the alarm number, and the desired action.
3. If the remote Spider receives the special command and it is
within 10 minutes of its own time, it will turn CONTROL 3 ON.
It will then send a response text message to the local Spider
acknowledging the command and stopping further sending
attempts by the local Spider. Go to step 6.
4. If the remote Spider does not receive the special command
or the command is not within 10 minutes of its own time, it will
ignore the message but still send the acknowledgement
command.
5. The local Spider
’
s text message acknowledgement time is
set to 3 minutes. If it does not receive an acknowledgement
from the remote Spider within that time, it will re-send the
special command. This process is repeated up to 3 times.
6. Auto Acknowledge time on the local Spider alarm is set to 60
minutes. Hence, 60 minutes after the alarm trigger, the alarm
will be auto acknowledged (if not already acknowledged by
the remote Spider). This will allow the alarm to send a new
series of text message commands if the water level goes
inactive (above 1 meter (39 inches)) and again goes active
(below 1 meter (39 inches)).
