Alarm
There are intelligent
communication failure alarms
in the monitoring unit's Alarms
- History page.
Improper cabling.
Check the cable clamp to ensure it's intact, and check if
the cable connection has been loosened.
After an alarm generates, the
notification system does not
respond properly. I'm receiving
less than three email or
SMSnotification (or none at
all).
Incorrect SMSmodule and mail server
configurations.
Verify that the notification configurations are correct.

blocked and possible workarounds.
Suspended telephone card. Confirm if the telephone card has been suspended.
If the above solutions do not resolve the issue, click Data & History - History Log. Check the log for

communication is busy.
When the first login system
has an alarm or a new alarm
generates, no alarm sounds.
Device volume is muted. Unmute the device.
Browser prohibits sounds.
Based on your browser, refer to the appropriate setting
configurations:
• Chrome: Go to Settings - Advanced -
Website Settings - Sounds. Check if

the Mute section. If so, delete it.

Check the box for Play sounds in web
pages, then click Apply.

communication being normal,
the login page is not
appearing.

Confirm the IP address is correct. As the unit uses two
network cards, ensure the Ethernet cable is plugged
into the proper interface. If the address is static, refer to
the Ethernet port in the monitoring unit section for the
default IP value.
