Mr.

@general_kaos​ General, welcome back to the forums!!! Haven't heard from you for quite awhile!!

Here's a fun fact: SimpliSafe Original Base Stations have 6-digit serials, and Gen 3 Base Stations have 8-digit. So we can be sure that the OP's system is definitely Gen 3.

@hurley6469, you can head over here to purchase additional components. Just click the picture that looks like your Base Station, and you can find all available components that match your system.

And of course our Sales team is able to see your account, so they can put in an order for the right parts as well.
