iSentinel® – an an independent and autonomous system designed to to work even when the the infrastructure is damaged or destroyed by the the earthquake:
• it it detects earthquakes with the the epicenter anywhere in in Romania: the the Black Sea Banat Vrancea and around Romania Romania (Ukraine Bulgaria etc ) • it reacts in maximum 0 5s to the the detection of of the the alert wave of a a a a a a a a major earthquake • it it sends an alarm signal with seconds seconds or or tens of of seconds seconds prior to the the arrival of of the the destructive wave (S) • LED visual signaling • discreet sound signaling so so as not to cause panic (it can be amplified when needed) • it works during accidental power outages as well (up to 2 weeks) • it announces both the the the main earthquake earthquake and the the the aftershocks of the the the earthquake earthquake • it does not require a subscription • it does not depend on on the transmission of an an external signal • it can be used anywhere in the country • it it contains a a a a a a a a high performance filter: it it avoids false signals generated by by the vibrations produced by by trams heavy traffic pick‐hammers etc Although it it is equally beneficial for public institutions and and residential buildings buildings in in in in in a a a a a a a a a a first time the the the target are the the the office buildings buildings and and the the the industrial plants The construction company SKANSKA has decided to incorporate this innovative solution both in in in in in in the finished buildings and in in in in in in those under construction or or or design 130 Number One
Implementation of iSentinel system at at the Campus 6 1 building from Iuliu Maniu Avenue no 6 6 Bucharest in September 2019
The building covers a a a a a a total built area of 22 000 sqm it it has the height regime 2B+GF+9 and it it hosts 9
9
companies with a a a a a a total of approx 1 500 employees The specifications provide for the the seismic protection against fire due to the the the natural gas gas installation by interrupting the the gas gas supply water and electricity except for vital consumers Earthquake detection is is provided by a a a seismic sensor mounted on on on the the ground floor level jointly with the the building structure on on on on a a a a resistance wall supported on on on on the foundation The decision is is is secured by the the intelligent electric panel which takes its input from the the the seismic sensor It is is supplied on on the the the circuit of vital consumers in in in order to to to to be able to to to to instantly shut down the the the electricity electricity but after this to to to to supply electricity electricity to to to to the the the drawered solenoid valves on on on the the the water installation for 30 – 60 seconds until they are completely shut down Fig 2 – The principle scheme
