WVRC-4 Plus Installation and Operation Manual

The Internet Down alarm allows the WVRC-4 Plus to monitor the reachability of a
specified DNS address or IP address using an ICMP ping. The ICMP ping is a
commonly used extension to the Internet Protocol (IP). ICMP supports packets
containing error, control, and informational messages. The PING command, for
example, uses ICMP to test an Internet connection.

the ping address before timeout(unreachable.)
