Issue - The control panel goes into alarm when the F220 Smoke Head is installed in an F220-B6C base. If I use the same smoke head and install it into an F220-B6R base, it works fine. What causes this problem
Solution - The wiring diagram for the F220-B6R uses terminals 1 and 2 as the alarm loop, whereas the F220-B6C uses terminals 4 and 5 as the alarm loop and terminal 1, 2, and 3 are the relay.
