Definitions

  • the dead-bolt 13 In the region of its forward end the dead-bolt 13 is provided with a peripheral groove 22 in which can engage an arm portion 23 of a rotatable latch 24.
  • the latch 24 is connected to a tension spring 25 which urges the arm portion 23 in a direction towards the dead-bolt 13.
  • the arm portion 23 is connected to an electrical solenoid 26 which constitutes the electrical operating system of the locking mechanism and which is energised in response to the "open" command signal from the electronic control system later described.
  • the dead-bolt 13 may be hollow, or partly hollow, and the tension spring 21 can be located within the hollow dead-bolt 13 so as to form a compact unit.
  • This system is the capability of being able to use a by-pass code to override the card encoding system. This facility is particularly useful in the case when the person who wants to gain entry has lost or damaged his or her card 28. The person has the option to use the by-pass code together with the four digit entry code to gain access.
  • the system is provided with the facility to be able to connect an external power source to the system through a connector (not shown) so that the system can be energised.
  • the external power source connector will include means for preventing short circuiting of the system during normal operation of the system.
  • a switch is provided for selecting the working channel.
  • Loss of entry code memory in the micro-processor can happen but is unlikely due to the stand-by battery. However, if the entry code is lost, access can be made with a valid card 28 and a valid by-pass code entry.
  • the electrical operating system can comprise two solenoids 26, one of which is used as a stand-by solenoid. Selecting one or the other solenoid can be effected through a switch provided on the central controller 34.
  • the door 16 can be provided with a conventional door handle 41 to operate a conventional latch-bolt 42 and with an auxiliary latch-bolt 43.
