ABSTRACT:
A fire safety apparatus particularly useful in association with Christmas trees comprising a smoke detector, circuitry for processing a signal generated by the smoke detector, an audible alarm, a moisture level sensor and circuitry for interruption of the flow of electricity to a receptacle. In the event of a Christmas tree fire, the smoke detector activates the circuitry which cause the audible alarm to be sounded. The audible alarm is sensed by a receiver which contains the circuitry for interruption of the flow of electricity and is in the form of one or more switches. Any appliances, such as Christmas tree lighting which are plugged into the receptacle, are deactivated by the interruption of electrical flow at the receptacle. Additionally, moisture sensing probes are provided which activate circuitry which cause the alarm to be sounded when the moisture level contained in a Christmas tree base falls below a certain level. Again, the circuitry activates one or more switches, thereby precluding the flow of electricity to the appliances plugged into the receptacle.
