Definitions

  • the invention relates to a fire protection switch for arrangement on a fire and / or smoke protection door or an arrangement of one or more fire protection switches and a fire and / or smoke protection door which closes an opening at least in case of fire.
  • Such fire switches are provided with a smoke detector and a triggering device. If the smoke detector has detected smoke, a locking device is triggered and released by the Festell engaged held in an open position fire and / or smoke protection door to move to a closed position.
  • fire protection switches are often mounted with other components in particular also components of the locking device or system in a housing above the fire and / or smoke protection door. Care must be taken during installation to ensure that there is a minimum distance between the upper edge of the housing and the lintel or ceiling above, so that the smoke to be detected can flow through the housing and the detection area of the smoke detector.
  • an aerosol detector that is mounted over a door and detects an aerosol when measurements of distances in different directions measure approximately equal distances.
  • This smoke detection principle requires a very high smoke concentration for a reliable smoke detection principle, since only then smoke is detected when due to the smoke density in all directions only equal distances are measured, ie distances that are smaller than the shortest distance between the sensor and its next surface. With such a high smoke density, the visibility is already limited to a few meters that orientation would be impossible and therefore closing a fire and / or smoke protection door would be much too late.
  • the invention is therefore an object of the invention to provide an arrangement of a fire circuit breaker on a fire and / or smoke door with a triggering device, wherein the fire protection switch reliably detects in the presence of an alarm criterion and thereby causes the door to close releases, and the fire protection switch so in To arrange the area of the door frame that this does not lead to unnecessary delays in closing.
  • a Rauchgastransportpfad is monitored, which engages through the opening to be closed by the door, so that the detection of smoke and / or combustion gases through the sensor is a criterion for whether the door in question is still passable. Closing the door then closes, for example, a fire compartment to be closed.
  • the at least one sensor is designed as a scattered light or extinction smoke sensor and / or as a gas sensor, which can be manufactured with sufficient sensitivity.
  • the fire protection switch can also be provided with several sensors at the same time, in this case preferably with at least one sensor of each type of sensor.
  • Space-saving and reliable detection can advantageously be an aesthetic aspects sufficient fire protection switch itself and / or be at least one fire detector without separation to a fall of the door or a ceiling.
  • the fire protection switch itself or its fire detector can be provided in an advantageous development, for example, on or in a slide on or with which the door is moved.
  • Another advantageous embodiment of the fire circuit breaker may be to arrange this itself or its fire alarm in a frame of the door.
  • switch or detectors can be on or in the frame of the door.
  • a reliable detection of smoke and combustion gases succeeds with an embodiment of the fire protection switch, in which at least one sensor of the fire detector is designed as a scattered light smoke sensor.
  • this sensor dispenses with a measuring chamber, which in turn would have to be flowed through and avoids such fluidic problem of the arrangement.
  • the detection area in this case the area in which emitted light is scattered by smoke onto the receiver, can be dimensioned so that it extends far into the room and thus large parts of a flue gas transport path can be reliably detected.
  • the housing may have at least a portion which is permeable to from within the housing signals emitting transmitter and the is formed from outside the housing backscattered, received by a receiver signals. It is important to pay particular attention to the installation of the fire detector in a door frame that the fire resistance of the fire and / or smoke protection door or its frame is not affected.
  • the housing and the radiation-transmissive portion of temperature-resistant, in particular refractory material which may be for the radiation-transmissive portion, for example, refractory glass.
  • the senor can be designed as an extinction smoke or gas sensor.
  • a first measuring path for measuring the light attenuation by smoke and / or a target gas outside the housing of the detector and outside the frame of the fire and / or smoke door in the vicinity of the lintel or the ceiling or at the upper inner edge of the frame is arranged and a second measuring section is arranged inaccessible as a reference measuring section within the housing and / or within the frame for the ambient air.
  • the senor in another expedient development of the sensor is designed as a gas sensor, in particular as a semiconductor gas sensor, suggests alarm, the risk of fire with the Criterion warns that the concentration of a combustion product, such as carbon monoxide, carbon dioxide, oxides of nitrogen or the like, exceeds a threshold, or detects a typical concentration pattern.
  • a combustion product such as carbon monoxide, carbon dioxide, oxides of nitrogen or the like
  • An advantageous development of the fire protection switch according to the invention can consist in that a gas-sensitive surface of the sensor is arranged in an edge region of the housing, in particular that the outer surface of the sensor at the edge region with a surrounding surface is flush, so that the fire detector on the surface in the to monitoring monitoring area looks and the gas does not penetrate into the housing of the fire protection switch to be detected there only.
  • the gas-sensitive layer is still protected from mechanical damage by a gas-permeable membrane.
  • the maintenance of the functionality of the fire detector is used when using a gas sensor, the assignment of a detection means for detecting a cover in particular a contamination of the protective membrane of the sensor in an advantageous embodiment of the fire circuit breaker.
  • the detection means may be formed as a separate sensor.
  • the at least one sensor of the fire detector of the inventive arrangement of a fire protection switch on a fire and / or smoke protection door is arranged such that the fire and / or smoke protection door engages in its closed position in the detection range of the fire detector.
  • the temporal development of the sensor signal can also be used to make a statement about the closed state of the door.
  • the passability of an escape route can be assessed remotely if the relevant information about the closed state of, for example, a group of doors is present.
  • the mentioned closed position is desirably recognized with high reliability.
  • the fire detector uses different signal levels for the evaluation.
  • the closed position of the fire and / or smoke protection door is based on a clearly above a smoke threshold of the sensor, high static signal level of the scattered light smoke sensor or a signal of the detection means of the gas sensor, which detection means originally the detection of a cover or pollution the gas sensor is detected.
  • Fig. 1 to 4 is a designated as a whole with 1 fire protection switch for placement on a fire and / or smoke protection door 10, shown in the episode simplistic simply called door 10, which closes an opening 20, wherein the opening enclosure formed by lintel 3 and or door frame 4 is.
  • the respective fire protection switch 1 is housed with the fire detector 2 in a housing 15.
  • a lintel 3 which engages over a door frame 4 in the direction in the viewing plane.
  • a fire protection switch 1 with a fire detector 2 is assigned which is integrated with a sliding rail 5 which moves the door 10.
  • the sensor 8 of the fire detector 2 is recognizable provided with a transmitter 7 and a receiver 6, which monitor the arranged below the fire detector 2 detection area 11.
  • the detection area 11 at least partially coincides with a smoke gas transport path 9 which extends through the opening 20 and is indicated by arrows.
  • the signal when the door 10 is closed can still be selectively influenced by reflecting surfaces on the door 10, not shown.
  • the fire detector 2 contains a plurality of scattered light smoke sensors 8, which operate at different angles and / or wavelengths
  • the closed position can optionally also be effected by comparing the measuring signals of the various sensors 8.
  • correspondingly normalized sensors 8, which operate with blue and red or infrared light would deliver signals of the same magnitude when the door is closed, while in the case of smoke, the sensor 8 will deliver lower values with red light than the sensor 8 which operates with blue light.
  • special sensors not shown, can be used to detect the closed position of the door 10, whose function is to detect a cover of the detector 2 or to monitor its surroundings for objects which may affect the air flow and thus the smoke gas transport.
  • This arrangement is able to detect the closed position of the door 10, as the Fig. 4 can be removed.
  • the front end 13 of the door panel 12 is located opposite the located in the door frame 4 fire detector 2 with sensor 8 in the closed position, so that the sensor 8 is able to recognize this state, be it that he this one Signal level of the actual sensor 8 or a detection means, not shown, which inter alia detects the cover of the sensor 8, evaluates.
  • the detection can also be based on the fact that the receiver 6 of the scattered light sensor 8 does not receive any light at all although the transmitter 7 emits light.
  • the detection of the closed position is based on the fact that the receiver 6 receives almost all the light emitted by the transmitter 7 light.
  • a not shown optical fiber is usefully attached to the door 10, which directs the light emitted by the transmitter 7 directly to the receiver 6 of the scattered light sensor 8 when the door 10 is closed.
  • the recognition of the closed position of the door 10 is also possible in the arrangement of the sensor 8 in the door frame 4, when the detection area 11 of the sensor 8 is not oriented downwards but to the side.
  • the closed position z. B. be recognized when the detection area 11 of the sensor 8 is covered with the door 10 closed by the stop of the door 10.
