Definitions

  • the present invention relates to the technical field of fire swing door systems. Also, the present invention relates to a method of operating such a fire swing door system.
  • Automated door systems can be found in various buildings today. Automated door systems often have an automatic door operator with drive means for driving the door leafs of the door system. In for example public buildings such as hospitals, automated fire doors are common. Automated fire doors serves to provide safe passage during fire or emergency situations while also, most importantly, entrapping the fire by rapidly closing when a fire alarm has been triggered.
  • Automated fire door systems are usually provided with a forced closing arrangement.
  • the closing arrangement is in most cases a mechanical system which may function even when the door operator controlling the opening and closing of the fire door is not provided any direct power by its power source.
  • forced closing arrangement may be in the form of pre-loaded springs or plummet arrangements.
  • Swing door systems are provided with one or more door leafs having one end pivotally connected to the door frame so as to allow for opening and closing in an angular movement of said door leaf.
  • Automated door systems are typically equipped with a control arrangement.
  • the control arrangement may be a part of the automatic door operator and commonly include a controller and one or more sensor units.
  • the sensors monitors a respective zone at the entrance system for presence or activity of a person or object.
  • the controller which may be part of the automatic door operator or a separate device, controls the operation of the automatic door operator - and therefore the automatic opening and closing of the movable door members - based on the output signals from the sensor units.
  • the sensors of the automated door systems may detect smoke and therefore prevent closing of the door due to the sensors not being able to separate between smoke and an object in the vicinity of the door.
  • This risk may be justified during a real emergency when it is vital for the door to close so as to not allow for spreading of the fire. But during for example calibration or testing, i.e. when the fire alarm is triggered where an emergency is not present it poses a risk for accidents for the operator testing and/or calibrating the door.

Since a presence detected due to smoke in the zone Z1 will cause the door leaf D1 to being kept in a closed position so as to avoid collision with the perceived person or object due to the smoke, present configuration allows for easier passage without increasing the risk for spreading of smoke or fire through the fire swing door system.
  • this allows for a safer configuration and testing process of the fire swing door where a fire alarm signal may be active when an operator is working on the fire swing door, since the first zone Z1 is still monitored by the sensor S1.

  • control arrangement 20 may be operatively connected to an additional fire swing door system, said additional fire swing door system having a control arrangement configured to generate the fire alarm signal, whereby the control arrangement 20 may be configured to receive said fire alarm signal.
  • the second mode may be associated with a lower kinetic energy of the door leaf, i.e. a lower kinetic energy of the door leaf in comparison to the first mode.

  • a fire swing door system which is in compliance with strict regulations regarding the maximum kinetic energy during automatic drive without functioning sensors as well as hospital standards regarding providing passage for patients even during smoky conditions is achieved.
  • the risk for collision is further mitigated due the fire swing door system having a more predictable behavior in line with the common provisions of a general swing door system. This being due to for example an installation in a hospital not requiring a complete deactivation of the sensors in order to comply with hospital escape route regulations during a fire.

  • the control arrangement 20 may be configured to activate said forced close arrangement close to the end of an opening cycle of the fire swing door leaf D1 so as to increase the closing speed of the fire swing door leaf D1 close to said end of the opening cycle.
  • the opening cycle is herein defined as the cycle of the swing door leaf D1 moving from an initial closed position to an opened position and back to a closed position.
  • the end of the opening cycle is herein defined as the part of the opening cycle associated with the swing door leaf D1 approaching the closed position after having been in an opened position.
  • the forced close arrangement thereby serves to increase the closing speed so as to reduce the time which the swing door leaf D1 is not in the closed position when a fire alarm signal is active. Consequently, the risk for fire and smoke spreading by passing through the fire swing door system is reduced.
  • the risk for the door leaf D1 to collide with a person or object is lower due to the short remaining trajectory before the door leaf D1 reaches its closed position.
  • the risk for fire and smoke spreading is reduced in a manner which does not significantly increase the risk for persons or objects getting pinched.
  • control arrangement 20 may be configured to activate the mechanical forced close arrangement when the opening angle ⁇ falls below a predefined angular value Y close to the end of the opening cycle.
  • the opening angle is herein defined as an angle defined in the opening direction from the closed position of the swing door leaf D1.
  • the predefined angular value Y is approximately 10 degrees.
  • the fire swing door system 510 may comprise an energy storing arrangement, such as for example an energy harvest switch.
  • the forced closed arrangement may thus be configured to be activated by means of the energy stored in the energy storing arrangement.
  • FIG. 4 a method of operating the above described fire swing door 510 is depicted.
  • the method comprises causing the automatic door operator 30 to operate in the first mode 1100.
  • the automatic door operator 30 is controlled based on sensor data obtained from the first sensor S1 and the second sensor S2.
  • the method further comprises receiving or generating a fire alarm signal and in response to receiving or generating the fire alarm signal causing the automatic door operator 30 to operate in the second mode.
  • the automatic door operator 30 is controlled based on sensor data obtained from the first sensor S1 and control of the automatic door operator 30 based on sensor data obtained from the second sensor S2 is disabled.
  • automatic drive based on sensor input is enabled on the first side of the swing door leaf.
  • the second mode may be associated with a lower kinetic energy of the swing door leaf D1 in comparison the first mode.
  • the kinetic energy of the fire swing door leaf D1 in the second mode may be between 1,5 and 1,8 Joule.
  • the kinetic energy of the fire swing door leaf D1 in the second mode may be approximately 1,69 Joule.
  • the closing force provided by the automatic door operator 30 may be between 100 Newton and 150 Newton in the second mode.
  • the closing force provided by the automatic door operator 30 may be approximately 133 Newton in the second mode.
  • the method comprises activating the forced close arrangement close to the end of an opening cycle of the fire swing door leaf D1 so as to increase the closing speed of the fire swing door leaf D1 close to said end of the opening cycle.
  • the second mode is associated with a predetermined maximum angular speed ⁇ ⁇ ax of the second mode for the swing door leaf D1.
  • the method further comprise causing the automatic door operator 30 to switch from the second mode to the first mode in response to the fire alarm no longer being generated or received.
  • the fire alarm may be a continuously active signal.
  • the control arrangement 20 may thus be configured to monitor the fire alarm signal so as to detect the fire alarm no longer being received or generated.
  • the method further comprise causing the automatic door operator 30 to switch from the second mode to the first mode in response to receiving a fire alarm termination signal.
