Definitions

  • the invention relates to a manual hazard detector according to the preamble of claim 1.
  • detectors for manual actuation namely manual danger detectors
  • push-button detectors Such detectors are usually manufactured in two versions.
  • the detector type B is an indirect actuation, a so-called push button version.
  • a glass pane must be broken in and the push button pressed, i.e. the trigger element is the button (control element).
  • the button pops out by spring pressure, i.e. the release element is formed by the disc (fragile element) plus the button (control element).
  • an electric switch is actuated by the push of a button, which forwards the alarm message as an electrical signal to the hazard alarm system. It is extremely important that these detectors function properly and are always ready for a safe alarm.
  • the push button In the known push button detector (type B), the push button is pressed in after breaking the glass pane. A bevel attached to the push button pushes a beveled switch button and thereby triggers the alarm signal.
  • Such a switching mechanism with this type Power transmission and deflection is common in precision engineering, but in the present case, when unfavorable circumstances come together, e.g. unfavorable tolerance, rough surface of the sliding surfaces due to production-related or subsequent dusting or one-sided button operation, it can lead to difficulties in triggering the alarm.
  • the object of the invention is to design the manual hazard detectors described at the outset in such a way that both a conventional printed circuit board with wired components and a preferably smaller printed circuit board with SMD components are used in the detector and optionally in the detector variants described above (type A or type B). can be used.
  • the manual hazard detector according to the invention in particular fire alarm, usually has a carrying element which is arranged in the detector housing and on which the actuating mechanism is attached.
  • the detector trough is arranged above it, through which the operating button protrudes and on which pictograms or characters are attached.
  • the support element is either formed from a printed circuit board for conventional assembly with wired components or from a carrier part with a preferably smaller printed circuit board for assembly with SMD components.
  • the support element is expediently locked in the detector housing, for example at three locking points.
  • the support element, conventional printed circuit board or support part is designed in such a way that the actuating mechanism can be snapped on.
  • the carrier part is provided with a trough-shaped area in which the SMD-equipped printed circuit board is arranged.
  • FIGS. 1 and 2 show the structural design of the manual hazard detector with a conventional printed circuit board 8 for wired components.
  • the circuit board 8 serves as a carrier for the entire detector use. It is locked at three locking points 14 in the detector housing 1.
  • This embodiment according to the invention enables the complete detector insert to be easily installed, it being possible for a carrier part 13 to be used instead of the conventional printed circuit board 8 in one and the same detector housing. This is shown in Figs. 3 and 4.
  • the structural design is shown with a relatively small SMD circuit board 8a.
  • the circuit board 8a is snapped into a carrier part 13, which in turn is fastened in a latching manner, for example, at three locking points 12 in the detector housing 1.
  • the carrier part 13 is generally designed as a plastic injection-molded part.
  • the actuation mechanism 19 is latched onto the carrier part 13.
