The electronic device of detection ALERT SISMA has been realized with RISC microprocessor connected with a digital sensor sensitive to minor variations in acceleration in the three spatial axes.
The box that holds the circuit board of the sensor has been conceived and designed in Italy especially to ensure the maximum of the quality and efficiency as well as durability.
For this reason the casing is very large in size and is made of shockproof material.
The main characteristics of the earthquakes detector are:
- Adjustable sensitivity with DIP switches.
- Notice of impending earthquake by internal siren and flashing light.
- Possibility to connect external sirens or other warnings.
- Possibility to control a solenoid valve for closing GAS.
- Possibility to control a solenoid valve for closing GAS if the earthquake exceeds a user-defined level (adjustable with DIP switches).
- Power supply 230V power <0.5W and - Backup battery rechargeable or alkaline battery saving function.
