Patent ID: 8847772

Claim:
A smoke detector comprising: a first power supply, an integrated circuit, a smoke detection component, an audible alarm, and an RF receiver, each of the foregoing being electrically connected as a circuit; the smoke detection component being in a normally open non-conductive state and being operable to detect smoke in the ambient air, the smoke detection component being further operable to change to a closed or conductive state upon the detection of a smoke condition, wherein the smoke condition corresponds to a predetermined quantity or density of smoke particles in the ambient air; the smoke detection component being in electric connection with the integrated circuit; the integrated circuit being operable to activate the audible alarm when the smoke condition is detected by the smoke detection component and being operable to command the RF receiver to operate at a higher power status when the integrated circuit has activated the audible alarm; the RF receiver in electric connection with the integrated circuit, the RF receiver being operable in a low power status to reduce battery usage; the RF receiver being operable at the higher power status upon command by the integrated circuit; a remote transmitter comprising an RF transmitter and a second power supply for silencing false or nuisance alarms, the RF transmitter being operable to transmit a signal sent by a user using the RF transmitter to the RF receiver, the RF receiver further being operable upon receipt of the signal from the RF transmitter to transmit the signal to the integrated circuit; the integrated circuit being operable to silence the audible alarm for a preprogrammed period of time while a remainder of the circuit remains active such that, if the smoke condition that activated the smoke detection component remains, the smoke detection component is always operable to detect the smoke particles; the integrated circuit being operable to reactivate the audible alarm upon the expiration of the preprogrammed period of time if the smoke detection component remains in the conductive state; and wherein each of the first and second power supplies is a self-contained battery.
