Outdoor Siren Power Modes

Hello AllDespite reading a lot of posts I am afraid I am still a bit confused about the way outdoor siren is powered. I understand powering the siren and powering dusk to dawn feature are two separate issues but what I want to understand clearly is if I were to use the Ring Plug In Adapter then will it power both the siren AND the dusk to dawn feature and there is no need for any other power?What I want is avoid the need for climbing up the ladder periodically to change anything. So, can someone please clear this up for me?So, to summarise, if I use the plug in adapter will that be all or do I need the additional battery pack as well to power both the siren and the dusk to dawn feature?Many thanks…
