  • For your critical applications of the Siren, consider using YoLink Control, YoLink’s unique device-to-device communication feature, which works without an internet connection. Maintain working batteries in your Siren, for operation during limited power outages (and without internet), for the ultimate in dependability, even during power outages
  • Protect your family, home, possessions, and property by using your Siren as a standalone panic alarm or as part of a group of YoLink devices configured for home security
  • Deter crime and be immediately informed if a door or window is opened or a motion sensor activated (per your app settings criteria: day-of-week, time-of-day, etc.)
  • Use the Siren Alarm to alert you immediately to critical environmental issues, before expensive repairs are required, by using YoLink sensors, such as the Water Leak and Temperature & Humidity sensors
  • Use the Siren Alarm to activate automatically and alert you to doors left open too long (door ajar alarm)
  • Teenagers sneaking out at night? Consider pairing the Siren Alarm with the Door/Window Sensor, as a deterrent and as an attention-getting alarm (without dispatching the police)
  • YoLink’s industry-leading long range communication allows for placing the Siren in your out-buildings, separate garage building, barns, greenhouse, etc.
  • Take your Siren Alarm and other YoLink security devices with you while traveling, to create a personal and mobile security system
  • Pair devices like door sensors to your Siren Alarm. Turn the Siren Alarm off to disarm your system, on, to arm it
