Definitions

  • the present invention generally relates to a notification device for issuing an alert to indicate an emergency, and in particular relates to a visual notification device used in a fire protection system, also called a visual alarm device (VAD) or optical alarm device.

  • VAD visual alarm device
  • optical alarm device Such a device is known e.g. from US 2004/0 218 391 A1 .
  • Visual alarm devices are widely used in fire alarm systems, being used to send out a visible alarm indication, e.g. high-intensity strobe light, to on-site personnel when an emergency occurs.
  • a visual alarm device (VAD) is connected to a control apparatus (control panel) via a field line or a wireless link.
  • the control apparatus can trigger the VAD via the field line, such that the VAD emits high-intensity alarm light visible to the human eye, to prompt on-site personnel to promptly evacuate a region of danger.
  • a VAD may be installed on a ceiling (abbreviated as “top-mounted” or on a wall (abbreviated as “wall-mounted”).
  • Fig. 1 demonstratively shows a schematic diagram of a wall-mounted VAD 100.
  • the VAD 100 is mounted on a wall W, and can illuminate a cubic space V that substantially has the shape of a cube or cuboid, wherein the VAD 100 is located at the mid-point of a top edge of the cubic space V.
  • the light intensity distribution on the surfaces of this cubic space V must meet the requirements of the relevant fire protection standard.
  • the cubic space V is also called the optical coverage volume, which is also the space specified in the relevant fire protection standard as needing to be illuminated by alarm light.
  • the alarm effectiveness of the VAD can be guaranteed as long as the room in which it is mounted is smaller than the optical coverage volume V.
  • LED light-emitting diode
  • VAD using an LED chip as a light source, which VAD can lower the performance requirements for single LED chips while meeting the requirements of the relevant standard.
