Require two key switches be turned together to enable the circuit?
Sounds more like the hardware in a missle silo.  I sure hope those 
safety
switches and keys along with software codes are not obsolete concepts!

Maybe they should have looked at Broadcast Tools audio switchers which 
can
be programed to require pressing an enable button along with the channel 
selection
button to make a change.

Problem is you can't have different switch arrangements for different 
alerts
if you don't want to befuddle and slow down an operator from sending out 
an
urgent alert.  And having to press more than one button to trigger an 
alert
doesn't mean they'll actually think about it and double-check their 
choice
before commencing.

We're all creatures of habit.  Even with software warning us, do we 
really
want to delete it?  How many of us have blindly gone ahead and poof!?  
Probably
all of us from one time to another.

Like the missle silos, the better check is having at least two people 
have to agree
to launch and having to operate switches real or virtual from more than 
one arm's
length apart.  For example, two folks would have to check off the same 
alert on two
separate screens/panels in order to arm it for transmission.
