NaSR Quake Alert Earthquake Detector Alarm

The device is designed to detect the P-wave, which is the initial, faster-moving seismic wave that travels ahead of the more destructive S-wave. By sensing this primary wave, it provides a few critical seconds of warning before the main shaking begins.

No, the unit operates entirely offline. It does not rely on internet or cellular networks, which ensures it remains functional even if the power grid fails or network congestion occurs during a disaster.

Yes, the device features adjustable sensitivity settings. This allows you to calibrate the sensor to filter out common, non-seismic vibrations like heavy traffic or nearby construction, ensuring the alarm only triggers for actual earthquake activity.

The rescue signal mode is a safety feature intended for use if you become trapped after a structural collapse. When activated, the device emits a distinct signal to help emergency responders locate your position.

The LED light is designed to activate automatically during a power outage. It provides immediate illumination to help you navigate your surroundings safely when the electricity goes out.

For optimal performance, the device should be wall-mounted in a stable, central location in your home or bedroom. Avoid placing it near heavy doors or areas prone to significant, non-seismic vibrations that could trigger false alerts.
