Abstract
A supervisory control system and apparatus used in a fire prevention system, a burglar alarm system, a remote control system, etc., in which progressive operation by continual selective signals is performed using a series of operating units in order to supervise and control each unit.
Claims11
A supervisory control system comprising
- a plurality of sensors;
- an alarm device for providing an alarm by activation of said sensors;
- a series of operating units, a given one of said sensors being associated with a given one of said operating units for providing a sensor signal thereto when said one sensor is actuated, each operating unit comprising a relay for activating a load and transfer means for transferring the operatable state of its corresponding operating unit, said relay being connected for actuation by a selective signal and/or a sensor signal, and said transfer means being connected to allow the operation of its corresponding operating unit by a selective signal and to make possible the operation of the next operating unit by the next selective signal;
- means for transmitting continual selective signals to said operating units;
- and
- display means for displaying information transmitted from said operating unit during the operation thereof.

- means for transmitting continual selective signals to saod operating units, said transfer means comprising a two-coil type self-maintaining relay having a transfer contact which is changed over by the transmission and/or the interruption of a said selective signal;
- and
- display means for displaying information transmitted from said operating unit during the operation thereof.
3 more elements
An apparatus for supervisory control comprising
- means actuable for generating at least one of a sensor signal and a selective signal;
- a plurality of operating units each having a load for actuating a driving device, a relay for activating said load, said relay being connected for actuation by a selective signal and/or a sensor signal, and transfer means for transferring the operatable state of the operating unit, which allow the operation of such operating unit by a selective signal and make possible the operation of the next stage operating unit by the next selective signal;
- and
- means actuable for transmitting a supervisory signal during the operation of the operating unit.
