Can I buy a second base station
Or do I need a second base station for my bedroom to hear if my daughter sneaks out at night
Hi @aparm. You would only need one Base Station for your Ring Alarm system, and this is included in every kit that you purchase. If the system is armed and a door or window is opened, this will trigger the siren which will play from the Base Station unit itself. It is typically loud enough to be heard within the whole house depending on how your home is setup, as everyone’s home is different. You can find an overview of how the system works in our Help Center Article here, which may answer any additional questions you have. 
My base station is no longer working. Am I able to order a new base station?
