I'd bet you could make something workable with a DPDT coaxial relay,
driving it from alarm contacts or a relay output of whatever
monitoring system you might already have. The tricky part would
probably be appropriately defining "failure" in order to get it to
automatically switch at the right time without causing more problems 
than you started with.
