Title
(EN) ALERTING DEVICE AND SYSTEM FOR ABNORMAL SITUATIONS
(FR) DISPOSITIF ET SYSTEME D'ALARME EN CAS D'ANOMALIES
Abstract
(EN)
A warning system for alerting a person to an emergency situation which includes a transmitter responsive to a visual or acoustic alerting system for transmitting an alarm signal on an RF carrier and a control signal on a sideband of the carrier. A tuneable receiver for receiving commercial broadcasts in a normal operating mode transfers to an emergency mode upon detection of the control signal and converts the alarm signal to an acoustic signal. In one embodiment, the visual or acoustic alerting system is a siren and light system of an emergency vehicle. In this embodiment, a transceiver is preferably included for dedicated communications among emergency vehicles. The range of both the transmitter and transceiver complement and are substantially the same as the effective range of the visual or acoustic alerting system.
(FR)
Système d'alarme servant à signaler à une personne une situation d'urgence, comprenant un émetteur sensible à un système d'alarme visuel ou acoustique, qui transmet un signal d'alarme sur une porteuse H.F. et un signal de commande sur une bande latérale de la porteuse. Un récepteur accordable permettant de recevoir des émissions commerciales dans un mode de fonctionnement normal commute en mode d'urgence lorsqu'il détecte le signal d'alarme qu'il convertit en un signal acoustique. Dans une forme d'exécution, le système d'alarme visuel ou acoustique est constitué par un système de sirène et feux de signalisation installé sur un véhicule de secours. On utilise de préférence un émetteur-récepteur afin d'assurer des communications privilégiées entre plusieurs véhicules de secours. Les portées de l'émetteur et de l'émetteur-récepteur sont complémentaires et sont sensiblement les mêmes que la portée effective du système d'alarme visuel ou acoustique.
