Abstract
1418190 Fire doors WON-DOOR CORP 16 May 1973 [23 May 1972] 23448/73 Heading A5A [Also in Divisions E2 and H2] A fire door 26 is moved to close an opening 12 by a mechanism comprising a pulley drive system 38 operated through an electromagnetic clutch 42, reduction gear 40 and motor 44 under the control of an electronic control system 46 which ensures closing of the door in response to a fire-warning signal and, by time-controlled means, causes the door to repeatedly open and close subsequent to the initial closing to enable persons in the building, of which the door is a part, to escape. System 46 is connected to a D.C. source by lines 48 and 50 which feed motor 44 in series with a switch component 54 and a current sensor 56 and through a reversing switch assembly 58 by means of which the motor is controlled for either closing or opening movement of the door. Actuation of switch assembly 58 is effected through a drive control component 60 to which drive-producing signals are fed from a pair of control logics 62 and 64 and these are triggered into operation by signals supplied from a gate circuit 66, though manual control is provided by a pair of switches 68, 70. Switch component 54 is normally energised whenever switch assembly 58 is supplying current to motor 44 and a load control component 72 is connected to switch assembly 54 to de-energise the motor momentarily during logic-controlled operation. Such operation is initiated by a signal from a fire detector 74 passing through a latching switch component 76, and an automatic repetative close logic 78 that generates operating pulses for transmission by gate circuit 66 to close logic 62. Whenever a signal is fed initially to logic 62 a signal is fed also to disable logic 80 through which a signal is fed to load control component 72 to render assembly 54 temporarily insensitive to motor overload. During logic-controlled operation the movement of the door will be momentarily checked if it meets an obstruction and when closed the operation is stopped by limit switch 82 which also triggers a timer component 84 which determines the time of sequential logic-controlled opening of the door before the door is finally closed and fire extinguisher component 86 is triggered into operation.
