According to our alarm system expert
The second generation of the Ring Alarm is a 7-piece set to secure your house with, including an outdoor siren. The alarm includes a base station, outdoor siren, and various sensors that you can connect to the Ring app on your phone. Via the app, you receive notifications when the sensor detects something. The system has a 24-hour emergency battery, so it keeps working when there's a power outage. In case the WiFi stops working, you can also use the optional mobile backup. In addition to the base station, the Ring Alarm pack includes the second generation of the following accessories: control panel, contact sensor (2x), motion sensor (2x), and signal amplifier. You can easily expand the system with extra sensors. You can even link other Ring devices in your home, like security cameras or the Ring doorbell.

Works easily, settings are extensive. Functions: "disabled" (all off), "home" (the alarm will go off when windows or doors open, but not when there is movement) and "away", all sensors are switched on. All sensors can be programmed in the same way.
