Example 2: We would like the system to fire alarm B with inverted polarity when the modula-
tion level has dropped below 30 kHz for longer than 15 seconds and release alarm B when the
modulation level rises above that level for 5 seconds. This is a way of detecting that silence
being transmitted.
Setup:
1. Navigate to Alarms ⇒ Alarm B
2. Select Type = Alarm
3. Select Source = Mod Level <
4. Set Modulation Threshold to 30kHz
5. Set Pin Polarity to -ve
6. Set On Delay to 15s
7. Set Off Delay to 5s
8. Set Send e-mail as required. Make sure emails are set up correctly if the feature is en-
abled (consult the relevant section in this manual)
Example 3: We would like the system to fire alarm C with normal polarity when the reverse
power increases above 10.35 watts for longer than 20 seconds. We would like the alarm to
be release if the reverse power decreases below 10.35 watts for longer than 10 seconds.
Setup:
1. Navigate to Alarms ⇒ Alarm C
2. Select Type = Alarm
3. Select Source = Rev Power >
4. Set Fwd Power Threshold to 10.35W
5. Set Pin Polarity to +ve
6. Set On Delay to 20s
7. Set Off Delay to 10s
8. Set Send e-mail as required. Make sure emails are set up correctly if the feature is en-
abled (consult the relevant section in this manual)
