And in particular the threaded rod secured to the motor output shaft is screwed directly into a threaded central bore of the bolt blocked in rotation by a rod mounted to slide in a receiving recess.
  • the lock is slaved to an electronic remote control, of the type comprising a key formed by a male plug provided with a plurality of pins and electrical resistors of indifferent values connected to said pins, the control comprising, on the other hand, a lock formed by a receptacle receiving said plug and comprising a device for measuring said resistances, so that the introduction into the base of the plug comprising the resistors of appropriate value, after measurement of the said resistances by the reading device of the base, controls the tilting of an electrical relay capable of driving the lock thus remotely controlled and the measuring device comprises resistors arranged on the base and able to be mounted each in series with each of the resistors included in the key, so that the sum of the values of each series of two resistors is always the same, thus making it possible to adjust once and for all the circuit of measurement, which checks a single constant value common to each resistor placed on the plug.

  • the wires are still under tension.
  • the set of two electrical limit switches F1 and 2 diodes D1 (see Figure 4), mounted on a printed circuit placed in each lock, causes the motor M to stop at the end of the bolt P in a direction, while authorizing its start in the opposite direction to the inversion of the polarity of the two supply wires and this, until the end of the stroke of the bolt P in the other direction.
  • a magnetic switch F2 (see figure 4), placed between the doorframe and the door, prevents the latches from operating when the door is open.

  • One of the poles of all 2 potentiometers P1 and P2 is connected to the + of the installation through a resistor R6, and the other pole is connected to ground, through the resistor to be measured.
