Outdoor Alarm Controller 2, Battery-Powered Siren/Alarm/Relay Controller, 12VDC Out, Up to 1/4 Mile Open-Air Range, 110dB Siren Included, YoLink Hub Required for Full-Functionality!

MORE POWER TO YOU! The features of our original Outdoor Alarm Controller, but now with up to 1 amp 12VDC power output! Control power-hungry devices like strobes or control multiple sirens, etc.
MULTI-FUNCTION! Use as a panic alarm, as a home intrusion siren, have it activate if a door or lid is left open too long, and use it as an alarm for water leaks* and high or low temperature and humidity* or all of the above! *Additional YoLink devices required, not included.
WIRE LESS! The Outdoor Alarm Controller 2 can power your siren or other 12VDC device WITHOUT the need for wiring from a 12VDC power supply; the power supply is built-in. Optionally, you can connect it to a 12VDC power source (not included), to extend the life of the batteries.
NO WIFI, NO INTERNET, NO POWER? NO PROBLEM! Our patented Control-D2D device-to-device pairing, over our LoRa-based wireless network, allows for devices to be paired to each other, in such a way they will continue to operate, even if WiFi is flaky, the internet goes down, or the AC power goes out!
EVEN BETTER with a SirenFob! Pair one or more siren products to your SirenFob, then pair one or more alarm products (such as door, motion, vibration sensors - ideal for vehicles, RVs, and other mobile applications or where internet is not available). *Additional YoLink devices required, not included.
START SMART! A YoLink hub is required for full functionality, including for the app to work, to check battery level, etc, but your hub is compatible with a growing family of smart products for home and business! Search for B09FSS95G9 for a SpeakerHub (our audio, talking hub) or B07TQLKQLJ for the original Hub.
BATTERIES INCLUDED! Four alkaline C cell batteries included.
