High-Sensitivity Photoelectric Sensing: The ZM-SM100-KGTY uses advanced photoelectric technology to detect smoke particles and heat. This “Fast Perception” feature is critical for providing the maximum amount of time for evacuation.
Voice & Siren Alerts: Features a built-in high-decibel siren with a Voice Alarm Prompt. This ensures the warning is heard throughout a wide range within the property.
New Gen Zigbee 3.0 Protocol: Engineered with a specialized low-power Zigbee chipset. It requires a Zigbee Gateway (like the ZMSG99) to sync with the Tuya Smart / Smart Life app and trigger other smart devices.
Security Scene Linkage: In the event of an alarm, you can program the system to automatically:
Turn on all smart lights (to light the escape path).
Unlock smart door locks.
Turn off the HVAC system (to prevent smoke from spreading).
Self-Test & Reliability: Includes a manual test button and automatic low-battery notifications to ensure the sensor is always in peak operating condition.
