Interconnected Smoke Detector (with HUB), Smart Compatible with Apple Home, Alexa and Google Fire Alarm, Replaceable Battery, Test Function -

HUB FOR 16 CONNECTED DETECTORS: The interconnected smoke detector requires an Apple HomeKit-compatible hub to connect to the network. One HomeKit-compatible hub can simultaneously control 16 devices. Before purchasing, check if you have an Apple HomeKit-compatible hub in your home. Note: This model (GS559AH) already includes the hub. If you don't need an additional hub, you can purchase the model without a hub (GS559A) to complete your setup. REAL-TIME ALARM NOTIFICATION AND REPLACEABLE BATTERY: The app or Apple Home will send you a warning message when the smart smoke detector detects smoke or high temperatures, when the batteries are low, or when there is a fault within the product. The smart alarm's batteries are replaceable and have a lifespan of approximately two and a half years. You can replace them with two 1.5V AA batteries. TEST FUNCTION AND TEST HISTORY: The smart smoke detector performs a self-test every 50 seconds to ensure it is working correctly. If you wish to test the alarm, a simple tap on your smartphone is all it takes. Each test will be recorded in the test history. The smoke detector supports the Apple Home app, Alexa, Google Home, and SmartThings, but some functions are exclusive to the app. SMOKE AND OVERHEAT DETECTOR: The smart alarm monitors not only smoke but also excessive temperatures (54-70°C). The fire alarm is also triggered when the temperature rises rapidly and reaches the detection range faster than the smoke. Faster alerts give people more time to react and escape. The smoke detector complies with EN 14604 and EN 50130 standards and is certified by Intertek and SGS. INTERCONNECTION FUNCTION: The smoke detectors are interconnected so that when one alarm detects smoke, all the other alarms are triggered. If there is an alarm in the living room and one in the bedroom, when the living room catches fire, the people in the bedroom will also be awakened. Whether you use the app, Apple Home, Alexa, Google Home, or SmartThings, this feature works as long as all alarms are paired under the same hub.
