Product Features
What this model is for, what it does well, and what to confirm before it goes on a project.
Indoor entry and window monitoring where a wireless reed-switch detector with tamper and low-battery alerts is needed.
Two-way frequency hopping communication helps keep the detector reliably connected to its receiver in busy wireless environments.
Low battery and tamper alarms give early warning so maintenance or interference is noticed before protection gaps appear.
Indoor temperature measurement with ±1 °C precision adds environmental awareness alongside door open and close detection.
