World's Longest Wireless Range: Powered by LoRa technology, the long-range yet low-power system offers the industry’s longest receiving range in the market (1/4 mile).

Economical and Powerful Siren: This economical wireless and portable LOUD 110 dB smart siren adds audible and visible alarms to your existing YoLink system or can work alone as a panic alarm (YoLink Hub required, not included). Add an attention-getting siren to your system to immediately notify you of water leaks/flooding, door and window status changes, and high/low temperature or humidity conditions, allowing you to respond quickly to critical events, protecting your family and your property.
Simple & Easy! YoLink’s Scan & Play smartphone app feature will have your siren up & ready in just a couple minutes! And the Siren Alarm could not be easier to install: just add it to the app, and place it on any stable surface or mount it to the wall with a screw or nail, for a more permanent installation. Done! Begin using your siren and enjoy security and peace of mind, knowing your family and property are protected.
Team Me Up! The Siren Alarm can be used as a stand-alone panic alarm (YoLink Hub required) but team it up with a Door/Window Sensor, or with a Water Leak or Temp Humidity Sensor and you’ll have an economical yet effective home & property protection system. YoLink app provides you with emails, text messages and phone banner alerts, tailored to your needs, but the Siren Alarm’s loud (100 to 110 decibel) sounder can be heard from a distance and gets immediate attention, with or without your pho
Doesn't Work without YoLink Hub: YoLink Hub is the only central controller for YoLink devices, and it connects YoLink devices into the internet and the cloud. Without YoLink Hub, this smart siren does not work with YoLink app and does not support 3rd-party integration with Alexa, Google Home and IFTTT.
