Description

WORKING PRINCIPLE:Like an alarm that can automatically make calls, when the sensor is triggered, it sends a signal to the control center, and the control center receives the signal and immediately sends out a 120dB alarm, and simultaneously makes a call or sends a text message/push notification to the mobile APP pop-up window
FLEXIBLE SETTINGS: Home Mode:To stay armed while we’re at home (if the motion sensor is fired, it won’t fire).Delay alarm:the siren starts working have a delay. Or armed delay:the system starts working have a delay. 24H SOS zone and so on
BUILT-IN BATTERY: all sensors have batteries, and the alarm center itself has batteries and is powered by current (so in case of power outage, the center will continue to work due to the battery, no worries)
DIY NAMES: In the Tuya Smart Life app you can name each device. When an alarm push notification is received, it will be clear which device is triggering the siren.Allows you to better identify where the alarm is goes off and deal with it calmly
SCALABLE: Pairing can be done directly using the alarm control panel or via the mobile app. Up to 100 sensors can be added.Wireless big siren can also be added for added deterrence
