It's purely for redundancy. If I detect an alarm, I simply check to see if it's coming from any of the CC's. If not, then the trigger alarm would have to be the CX. So again, I'll know where the fire is. But if I'm not at home, then this way I have some redundancy because otherwise, being CC's, they're almost a single-point failure as far as the Elk detecting anything. But with the CX, then as long as the tandem line works, the Elk will still get notified.
Mixing the two types gives me the benefits of both. Maybe a little overkill, but smoke alarms is a good place for that.
