Humanized No-Disturb Feature
When the combo alarm sounds like a low battery alarm or other failure alarm, we can press the silence button to get 10 hours of no-disturb to avoid disturbing our sleep at night.
Protection Upgraded with Higher Accuracy
Besides smoke and CO, the inbuilt UL listed sensor of GS888A also detects moisture, which can effectively minimize the false alarm that sounds when we are cooking.
Dual Emitter Photoelectric Smoke Sensor
Dual emitter sensing technology designed to minimize nuisance alarms
Convenient Full Cover Test/Hush Button
Alarm hush feature to help reduce noise temporarily from known nuisance alarms
3-Color LED Indicator of Working Status
Green LED: Power (Normal). Yellow LED: Sensor Failure/Low Battery/End of Life (Fault). Red LED: Alarm

FAQ
2.How does the alarm detect smoke and carbon monoxide?
This alarm uses photoelectric and electrochemical sensors to quickly and accurately detect smoke and CO. The photoelectric sensor detects smoke by sensing changes in light scattering, while the electrochemical sensor detects CO by measuring changes in electrical current.
3.How do I silence the alarm if it goes off?
If it goes off, you can silence it by pressing the silence button on the device. The silence mode will last for 8 minutes for smoke alarms and 5 minutes for carbon monoxide alarms. After this time, the alarm will automatically reset.
4.How do I test the detector to make sure it's working properly?
To test this detector, press and hold the test button on the device for a few seconds. The alarm will sound and the LED light will flash to indicate that it's working properly.
5.How do I connect this device to my Wi-Fi network?
To connect it to your Wi-Fi network, download the Tuya Smart app and follow the instructions in the app to connect the device to your network.
