What's in the Ring Alarm 5-Piece Kit?

The Ring Alarm 5-Piece Kit contains the five core components of a complete home security system: a Base Station (the system brain with cellular backup and 104dB siren), a Keypad (for arming/disarming with PIN), a Motion Detector (PIR sensor, battery-powered, adjustable range), a Contact Sensor (for a door or window), and a Range Extender (Z-Wave signal booster for larger homes).

This combination covers the primary entry points of a typical UK front-door and main living area. For complete coverage of a larger home — multiple doors, multiple entry-level windows, upstairs coverage — additional sensors are purchased separately and added to the system without tools or professional installation.

No Subscription Required

The Ring Alarm works fully without a paid subscription: the siren sounds on triggered motion or contact events, the Ring app sends push notifications, and the system can be armed and disarmed by keypad or app. This distinguishes Ring from most monitored security systems that require monthly subscription commitments of £15–30 to activate the alarm response service.

Ring Protect Pro (optional, approximately £10/month or £100/year) adds 24/7 professional monitoring, cellular backup activation, and extended video recording for Ring cameras. This subscription is optional and additive — the basic system is fully functional without it. For households who want the deterrent and self-notification value of a security system without recurring costs, the no-subscription operation is the primary appeal.

Self-Installation

No drilling, no wiring, no professional visit. The Base Station plugs into a power outlet with an Ethernet connection to your router. The Keypad attaches via the included mounting plate (adhesive or single-screw options). The Motion Detector and Contact Sensor mount with adhesive strips or a single screw. Total installation time for the 5-piece kit is approximately 30 minutes following the Ring app setup wizard.

The Z-Wave mesh network the components use means each device extends the signal range for others — no specialist radio knowledge or configuration is required. Adding additional sensors and components to an existing Ring Alarm setup follows the same pattern: app setup wizard, position, adhere or screw mount.

Alexa Integration

Ring is an Amazon-owned company, and the Alexa integration is consequently deep. Voice commands arm and disarm the system, check system status, and interact with Ring cameras. "Alexa, arm Ring in away mode" activates full perimeter monitoring when leaving the house — useful when hands are full with bags or a child. The integration works with any Alexa-enabled device including Echo speakers and Fire TV sticks.

Google Home integration is more limited — basic arming/disarming is possible but the ecosystem fit is less cohesive. Ring Alarm is an Amazon-ecosystem-optimised product; Google Home households may find the SmartThings or Arlo alternatives better integrated.

The Base Station Siren

The 104dB siren in the Base Station is genuinely loud in enclosed home environments — comparable to a smoke alarm in immediate impact. The siren's purpose is twofold: immediate deterrence (most intrusion attempts are opportunistic and a loud alarm encourages departure) and notification to neighbours who can call police or check on the property.

Entry delay is configurable — typically 30–60 seconds — allowing keypad disarming before the siren activates. Motion sensitivity on the PIR detector is adjustable to reduce false triggers from pets under a specified weight threshold.

Cellular Backup

The Base Station includes cellular backup that activates if your broadband connection is cut — relevant for intrusions specifically attempting to defeat the alarm by disconnecting internet (a real, if uncommon, attack vector). The cellular connection requires a Ring Protect subscription to function actively, though the sim hardware is included in the device.

Expanding the System

Beyond the 5-piece kit, Ring offers additional Contact Sensors (£20–25 each), additional Motion Detectors, an Outdoor Siren, a Panic Button, and Flood/Freeze Sensors. Ring cameras (Video Doorbell, Spotlight Cam, Floodlight Cam) integrate into the same Ring app ecosystem for a combined security overview. The incremental expansion model is a strong argument for Ring as a first security system — start with the kit, add components as budget allows.

Verdict

The Ring Alarm 5-Piece Kit at £249 offers professional-quality home security features without professional installation costs or mandatory monthly fees. At 4.7 stars from over 1,000 reviews, the system's reliability and ease of setup are well-validated. For Amazon/Alexa ecosystem households, the integration is seamless. The base kit covers core coverage; the expandable sensor ecosystem means it scales with your property and budget.

Rating: 4.7/5 — Excellent deterrent, no mandatory subscription, Alexa-native integration, professional monitoring available optionally. Amazon ecosystem optimised — less ideal for Google Home households.
