You’re using the hardwired input of the 6022 to connect to the Normally Open output of the duct detector? Which hardwired input are you using LP1 or LP3? This will determine the LOOP number you will need to assign under the Wireless Setup for the Zone. When the duct detector goes into alarm how do you want the M1 to respond?
