I installed the Smoke/CO listeners to my system per the intructions. The instructions indicated that when you put the Smoke/CO listeners through the test mode, that you deactivate (remove the battery from the Smoke/CO listener) any other Smoke/CO listeners you may have installed.
I did that, but now can’t seem to get the other Smoke/CO listeners back online. Their status simply shows up as “tampered” and I can’t figure out how to reset or clear them and get them back “online.”
