Definitions

  • Existing fire alarms may be linked in to an intruder system.
  • smoke or heat detectors are placed in strategic places around the building. They are commonly mounted on a ceiling and connected by hidden wiring to a central alarm unit. When one of the detectors is triggered the alarm unit activates one or more sirens to alert the occupants.
  • US 3969720 describes an emergency alarm and evacuation system for directing persons to an emergency exit.
  • the system includes an alarm, a plurality of indicator units arranged in a line toward the emergency exit, and an operating unit coupled to the alarm and being operable in response to an output signal from the alarm to successively energize the indicator units in the direction of the exit.
  • the indicator units each have a light and a buzzer so as to generate both an audible and visual indication.
  • One problem with such a system is that, even if one of the indicator units is visible in a smoke-filled area the next indicator unit might be totally obscured.
  • the audible indication does little to solve the problem if the occupants are hard of hearing, and ambient noise levels also tend to be elevated in an emergency situation.
  • WO 2012 069 782 A1 discloses an emergency guidance display comprising three or more light points arranged in a line and a control means, in which the control means illuminates said light points sequentially from one end of the line to the other in a first mode of operation and sequentially in the opposite direction in a second mode of operation, in which said light points comprise two groups, and in which the control means illuminates the light points of each group sequentially along said line in opposite directions in a third mode of operation.
  • the present invention provides an emergency evacuation installation having a control unit (10) configured to send out an activation signal in response to the alarm signal.
  • the present invention provides an emergency evacuation installation having indicator units (14) which include a housing (20), a power source (21) within the housing for powering the indicator unit, and an electronic controller (22) to energize the light emitting elements (26).
  • indicator units (14) which include a housing (20), a power source (21) within the housing for powering the indicator unit, and an electronic controller (22) to energize the light emitting elements (26).

Abstract

L'invention concerne un appareil qui comprend des détecteurs (11) qui réagissent à une condition potentiellement dangereuse, telle que la fumée ou la chaleur. Les détecteurs sont connectés par des fils (12) à une unité de commande (10) qui envoie un signal d'activation sans fil lors de la réception d'un signal d'alarme provenant d'un détecteur. Des unités d'indicateur (14) configurées pour être activées par le signal d'activation sont installées à divers emplacements pour diriger des personnes vers une sortie d'urgence. Chaque unité d'indicateur est montée sur une surface verticale au-dessous du niveau de l'œil et comprend un boîtier ayant une source d'alimentation et un réseau d'éléments électroluminescents séparés. Un dispositif de commande électronique met sous tension les éléments électroluminescents dans une séquence qui fournit un affichage vectoriel mobile pour diriger des personnes vers une sortie d'urgence. Les unités d'indicateur sont configurées sous la forme de répéteurs RF et envoient d'autres signaux d'activation à d'autres unités d'indicateur à portée.
