Definitions

  • This invention relates to alerting systems and is particularly directed to an alerting system which responds to a signal from one or more sensing devices by activating a telephone, dialing a preselected number_ and enabling the party called to hear the events transpiring at the pro ⁇ tected location.
  • the Ronald E. Olsen, etal patent discloses an alerting system which responds to a sensing device by activating a telephone and transmitting a beeping signal over the telephone line.
  • Olsen merely provides a warning that something is amiss at the protected loca ⁇ tion, but gives no indication as to the nature or extent of the problem or whether the problem is continuing.
  • Olson's system does not advise whether an intruder is still present or has simply broken in and fertil. Obviously, this would be extremely valuable information for persons investigating the matter.
  • the John M. Sues, etal discloses a system which responds to one or more sensing devices by activating a telephone and transmitting a digitized signal announcing the nature of the event.
  • the Sues system is extremely complex and, hence, exepnsive to purchase and install and will be subject to extensive "down-time” and expense for maintenance.
  • Sues's system still does not provide any indication as- to the extent or con ⁇ tinuance of the event.
  • Each of the prior art alerting system senses the occurrence of an undesired event and provides a warning that such an event has occurred.
  • none of the prior art alerting systems provides any indication as to the current status of the protected location. Thus, if someone throws a rock through a window of the protected location, the alerting system may provide a warning signal. But the prior art systems give no indication as to whether or not a burgler has entered and is currently on the protected premises. Obviously, such information could be of considerable value in determining how to respond to the warning signal.
  • the prior art alerting systems are considerable more complex and expensive to install and maintain than the system of the present invention.
  • the disadvantages of the prior art alerting systems are overcome with the present invention and an improved alerting system is provided which responds to one or more sensing devices by activating a telephone system, dialing a preselected number and enabling the party phoned to actually hear the events taking place at the protected location. In this way, the party phoned can determine the nature and extend of the event and whether the event is continuing.
  • the present invention is ex ⁇ tremely simple in circuitry and compact in size. Therefore it is inexepnsive to purchase and maintain and, if desired, may readily be installed within the housing of a conven ⁇ tional telephone to which it is connected.
  • an alerting system having at least one triggering device for sensing an unsafe condition and generating electrical signals in response thereto, a telephone, actuating means connected to said triggering device and to said telephone and responsive to the elec ⁇ trical signal from said triggering device- to activate said telephone and to cause said telephone to dial a pre ⁇ selected phone number and to eanble the party called to hear the events actually occurring at the protected location.
  • the inventive alerting system responds to the signal from the sensing device by activat ⁇ ing the telephone and placing a call to a preselected phone number. When the party called answers the telephone, they can hear the events actually in progress at the protected location.
  • the party called can determine from the sounds coming over the telephone whether or not the burgler is still on the protected premises. Hence, he may decide whether to call the police immediately or to first inves- tigate the matter himself. This minimizes the likelihood of placing false alarms, yet protects the shop owner against walking into a potentially dangerous situation.
  • the alerting system can be made to dail addi ⁇ tional telephone numbers as well, for example, the police and/or fire departments so that they can also hear the events transpiring at the protected location. This has the further advantage that the additional telephone calls are connected simultaneously, in the nature of a "confer ⁇ ence" call.
  • the property owner can discuss the matter with the police and/or fire department represen ⁇ tatives to determine the best course of action.
  • Another object of the present invention is to pro- vide an improved alerting system which responds to a signal from a sensing device by telephoning a preselected party and enabling the party called to hear the events actually occurring at the protected location.
  • a specific object of the present invention is to provide an improved alerting system having at least one triggering device for sensing an unsafe condition and generating electrical signals in response thereto.
  • the invention includes: a telephone, an actuating means con ⁇ nected to the triggering device and to the telephone.
  • the actuating means is responsive to the electrical signal from the triggering device and activates the telephone that causes the telephone to automatically call a preselected phone number and enable the party called to hear the events actually occurring at the protection location.

More ⁇ over, if desired, sensing devices which generate only audible signals may- be employed and a microphone 6 could be connected, in lieu of or in addition to the triggering devices 4, to generate an electrical signal in response to the actuation of the audible signal.

  • one device might employ a bell as an audible signal, while another device might employ a horn. In this way, anyone hearing the warn- ing signal can immediately determine the nature cf the • problem from the sound of the audible signal.

Abstract

Un système d'alarme téléphonique amélioré (2) comprend au moins un dispositif de déclenchement (4, 6), qui détecte une condition d'insécurité et produit un signal électrique en réponse à la condition d'insécurité. Le signal est appliqué à un circuit électronique composé en partie d'une horloge (8) et d'un relais (10). Lorsque le relais est énergisé, il fait passer un signal qui active un poste téléphonique (34), où est installé un système, et ouvre la fourche interruptrice (12) du poste téléphonique. Le téléphone activé appelle automatiquement un ou plusieurs numéros de téléphone présélectionnés. Ainsi, lorsqu'elle répond à l'un des numéros présélectionnés, la personne appelée peut entendre, à travers la fourche interruptrice ouverte, les évènements qui se produisent à l'endroit protégé où est installé le système (2). Le système (2) donne par conséquent des indications sur l'état dans lequel se trouvent les locaux protégés à ce moment, sans recours à des circuits complexes.
