Ring Alarm 5-Piece Kit

The Ring Alarm 4K11S7-0EN0 kit delivers a complete home-security system with a Base Station, Keypad, Motion Detector, Contact Sensor and Range Extender. All components connect through the Ring App for real-time alerts and remote arming from a phone or tablet. Installation requires no tools and takes minutes on any apartment or house. Optional 24/7 professional monitoring adds a dedicated response team without a long-term contract.

Renters and homeowners wanting tool-free

This kit suits anyone who wants immediate, app-driven security with optional professional monitoring and no wiring expertise. It does not suit buyers who need integrated smoke or water-leak detection, outdoor cameras or hard-wired sensor loops. The system relies on AC power with a 24-hour backup battery and optional cellular backup for continued operation during outages.

HomeKit protocol with 24-hour backup battery

The Base Station runs on 100-240 V AC and includes a rechargeable battery that maintains protection for 24 hours if mains power fails. HomeKit protocol support lets the system integrate with Apple Home automations alongside Alexa voice control. Cellular backup is available as an optional add-on to keep monitoring active when the internet connection drops.

Questions about this item

How much wall space does the Base Station need for its 6.65" x 6.65" footprint?

The Base Station measures 6.65 inches square and 1.42 inches deep, so allow a flat surface at least that large near a mains socket for the included AC adapter.

Which component is the one people forget to pair first during setup?

The Range Extender plugs into a standard outlet and must be added in the Ring app before the Contact Sensor and Motion Detector will communicate reliably with the Base Station.

How often will the Base Station's backup battery need replacement?

The built-in 24-hour rechargeable battery is designed to last several years; replace it only when the app reports a low-backup-battery warning.
