🚨 Many Uses! Burglar alarm, panic alarm, intrusion siren, trespassing and theft deterrent - activate the siren manually from the app and/or by motion detection or other automations (using the convenient free YoLink app)

🚫🛠 Wireless & Flexible! Self-powered and wireless controller, just install the siren and controller wherever it is needed. No additional wires needed! Or, install the Controller connected to existing wiring, with the siren installed outside. (Both are outdoor-rated, but installing the Controller in plastic junction box or enclosure to protect wiring from elements, etc, is recommended)

2️⃣>1️⃣ Team Me Up! The siren & Controller is best when teamed up with other YoLink products such as our Outdoor Motion Sensor, AlarmFob and FlexFob, as well as Plugs and In-Wall Switches for flood lights and other exterior lighting control: activate the siren upon detection of activity on your property after-hours, and turn on flood lights to deter criminals and alert others

📡 Longest Range, By Far! Only YoLink, powered by LoRa is capable of up to 1/4 mile range in open air, allowing you to locate the siren virtually anywhere on your property, with no concerns about WiFi signal or dependability
