DFM is a device fault management application. It doesn't do any network-level correlation. Therefore, the ability to digest a router going down into a site event is not possible.
It sounds to me like your Notification Group could use some work. Make sure you have not checked any of the boxes under Alerts in your Notification Group. Only check the Event boxes. This will limit your notifications to the atomic events (with all the juicy details) when they become active, and when they clear.
Configuring a threshold for reachability is not really possible. You can adjust the polling interval and the SNMP timeouts, but as soon as DFM cannot ping or poll the device, it's considered down. These settings can be adjusted under DFM > Configuring > Polling and Thresholds > Polling Parameters.
