Re: Natural gas detectors and Co detectors

[Jim Rojas <jrojas@xxxxxxxxxxxx>]

I had my Vista20P originally setup for zone doubling. I had my 2 wire
smokes on zone 1. I was still able to use zone 9 as a wireless zone. But
soon afterwards, I threw in a 4219 to keep things simple. I am no fan of
zone doubling.
