Easy to install as an integrated unit! Outputs P-wave alerts, real-time seismic intensity alerts, and acceleration alerts.
"FREQL-LU" is an onsite early earthquake detection alarm device that integrates an alarm system, allowing for easy installation and removal. During shaking, the RI is calculated every 1/100 of a second, displaying the maximum seismic intensity in real-time up to that point. It identifies the detected vibration as a P-wave (P-wave detection) and outputs an alarm within the fastest 0.1 seconds after detection. It also outputs seismic intensity alarms and acceleration alarms. 【Features】 ■ Real-time seismic intensity (RI): Patent registered ■ Outputs world-class fast P-wave alarms, real-time seismic intensity alarms, and acceleration alarms ■ The seismic sensor and alarm system are integrated for easy installation ■ Operates for approximately 30 hours on battery ■ Alerts individuals carrying a wireless receiver with vibrations and a buzzer * Optional * For more details, please refer to the PDF document or feel free to contact us.
