Seismic Detector MS04 

Seismic Detector for the alarm against burglary attempts made at the expense of building structures in reinforced concrete, safes, cabinets armor, Automated Teller Machines, etc.

As MS04 but with dustcover device for protection of safes with a possibility to discriminate between three positions: lock indoor lock discovery and intermediate.

Microprocessor technology with fully digital sensor management.


MS04 COD. 80MS0800211
