Smoke alarm verification is sometimes a requirement, depending on your location, or the type of premises. Some monitoring companies even require it. In any case its not supposed to add more than 90 seconds, but of course, every second can count. If your area doesn't require it, then certainly you don't need to activate it, but the option is there for when its required.RAL said:4. Not sure if you mean the "auto verified fire" feature. For me, I wouldn't use the auto verify, as I view it as slowing down the notification of the fire department until the condition is verified (unless a second zone trips). I wouldn't want to delay the response, even if just one zone trips. It might seem like a nice way to filter out false alarms, but if you properly install the smokes, there should be few false alarms.
