Imou Smoke Detector, monitoring both smoke and room temprerature, Local sound and light alarm, ZigBee

The ZSM1 Smart Smoke Detector is EN14604 certified, a Zigbee device requiring
a gateway, and supports
remote
alarm message push and remote silencing (Without a gateway, the smoke detector can function normally and
provide local alarms, but it cannot achieve network connectivity or linkage functions). It boasts a
five-year
battery life and an alarm sound level is above 85 dB. It supports multi-device linked alarm
functionality,
meaning
that if one smoke detector triggers an alarm, all others will also sound, even without a network
connection.
Alarm messages can be shared with other users via an app.
