Sounds like BS to me.

I don't do commercial fire ..... and I can see your point if using two
telco lines ..... but if you've got one telco line and one cellular
back up. which is the better way to go ..... if one technology goes
down the other can still transmit a fire signal.

If  you've only got one technology and it goes down and the only way
you know is due to a lack of supervisory signal, there's no way to
monitor the premise for fire between the time you lose supervision and
the time it's repaired. Unless your're going to roll the trucks when
you lose supervisory signal.

Sounds like the same flawed logic that was the demise of Derived
Channel telephone line monitoring.
