YoLink X3 Outdoor Alarm Controller 130dB Siren

Designed for harsh conditions, the X3 combines a weatherproof IP65 enclosure, a built-in 12VDC power output, and an included hub for simple integration with Alexa, Google Assistant, and IFTTT. Its LoRa-based Control-D2D pairing keeps devices communicating even when Wi-Fi, internet, or AC power fail, and the replaceable 19000 mAh lithium battery provides over a decade of standby life for low-maintenance protection.

How loud is the siren and where will I hear it?

The X3 produces up to 130 dB, which is comparable to emergency vehicle sirens and is designed to attract attention at distance. It's tuned for outdoor use and can deter intruders while alerting neighbors and passersby.

• 130 dB peak alarm output for maximum noticeability.
• IP65 housing preserves sound performance in rain or dust.
• Built-in horn design optimized for outdoor dispersion.

What makes this unit reliable when internet or power go down?

YoLink's patented Control-D2D technology uses a LoRa-based network so devices can pair and operate directly with the hub and each other. That means alarms and relays continue to trigger locally if Wi‑Fi, broadband, or mains power are unavailable.

• Local device-to-device pairing prevents single-point failures.
• LoRa wireless delivers long-range, low-power communication.
• Included hub supports cloud features when available, but isn’t required for local operation.

How long will the battery last and can I replace it?

The X3 ships with a large 19000 mAh lithium battery that YoLink rates for over 10 years of standby life under normal conditions. Batteries are replaceable, keeping the unit serviceable for many years without the need for hardwired power.

• Replaceable 19000 mAh lithium pack included.
• Over 10 years standby life reduces maintenance cycles.
• Battery status and alerts available through the YoLink app and hub.

Can I use the X3 with other smart home platforms and accessories?

Yes. The package includes a YoLink hub and supports Alexa, Google Assistant, and IFTTT for convenient voice control and automation. The X3 also supplies a powered 12VDC output so it can drive external sirens or devices without additional wiring.

• Works with Alexa, Google Assistant, and IFTTT integrations.
• Built-in 12VDC output powers external sirens or relays wirelessly.
• Pairs with YoLink accessories like key fobs and sensors for custom setups.

Who is this for: The YoLink X3 is aimed at homeowners, landlords, and small-business operators who need a robust outdoor alarm solution that functions independently of mains power and internet connectivity. It suits properties requiring long-range wireless coverage, low upkeep, and the ability to integrate with smart home assistants without ongoing subscription fees.
