  • control means 9 can be supplemented by suitable means to ensure the inactivation of these control means 9 when the final blade 7 is located in the immediate vicinity or in contact with threshold 23 of a door, window or the like equipped with said shutter rolling 1.
  • such means inactivation can be defined by a stopper that comprises said roller shutter 1, more particularly at the level from one of the side slides 6,6 '.
  • a stopper that comprises said roller shutter 1, more particularly at the level from one of the side slides 6,6 '.
  • Such a stop is designed to cooperate with the deck 3, in particular with the blade final 7 of the latter, this when this final blade 7 located in the immediate vicinity or in contact with said threshold 23.
  • the threshold 23 of cause deformation of said device 10 during the unfolding of the deck 3.
  • these inactivation means are associated with either the RC resistance measurement means of the circuit 24, or to the means for comparing the values of resistance (RC, RD) mentioned above.
  • Such inactivation means can then be supplemented by suitable timing means, after a certain period of time (in particular suitable for being programmed), reactivating the means 9 and / or to stop the engine 8.
  • Such an embodiment makes it possible to immobilize said apron 3 in at least partially openwork position.
  • control means 9 defined by at least one suitable device 10 to react to deformation, are connected to a central alarm (not shown) for peripheral protection of a building, more particularly of a dwelling.
  • this central alarm is likely to be activated, directly or indirectly, by the control means 9, in particular by depending on the characteristics of the electrical signal emitted and / or modified by device 10.
  • such a rolling shutter 1 can be designed so that the said alarm center is capable of to be activated whatever the state (in motion or at the stop) and / or the position of the deck 3 (complete blanking or partial, open position ).
