Voice Alarming (if voice option is installed)
If voice sending is enabled, the Spider will dial the first voice number.
If the call is answered, the Spider will identify itself and verbally
communicate the alarm message. The recipient can acknowledge the
alarm. Acknowledging the alarm will stop all further text message, e-
mail, and voice transmissions.
If the alarm call is neither acknowledged nor answered or the line is
busy, the Spider will call the second voice number after 2 minutes. If
this call is also not acknowledged, not answered or is busy, the
Spider will call the third voice number after 2 minutes.
The whole sequence will be repeated up to 3 times. Please refer to
Voice Option on page 70 for more details on the Spider Voice Option
operation.
Control Activation and Deactivation
Alarms can also be used for intelligent control of various systems. For
example, a tank level can be maintained by monitoring a water level
and by controlling a pump. One alarm is set to trigger when the water
level falls below a low level. This alarm is programmed to activate a
control output, which, in turn, switches on the pump. A second alarm
is set to activate when the water level is above a high level. This
second alarm is programmed to deactivate the same control, which
switches off the pump. Thus, the tank level is automatically kept
between the two levels.
Alarm Acknowledgement
Active alarms can be acknowledged in four different ways:
1. By accessing the
“

page with a browser and clicking
on the active alarm
2. By sending a text message to the Spider
3. (GSM systems only) By acknowledging the alarm with the
phone keypad during a voice call
