Abstract
Abstract A wireless smoke alarm system in which each detector includes a local smoke detector and an alarm. These are coupled to a transmitter and a receiver. The transmitter and receiver are within range of similar units so that an alarm sounded by one unit causes those within range to sound their respective alarms. In sounding their respective alarms, the local units also cause their transmitters to transmit alarm signals thereby overlapping and reinforcing the first unit. A master control is coupled between the alarm detection and local alarm portion and the transceiver to disconnect the unit when the alarm is ended and to transmit a signal to other units, causing each to discontinue their respective alarms.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
239 words
A detection system of the type intended to detect the occurrence of a local phenomena, and transmit at least one signal to other detectors to remotely sound an alarm, said system comprising: I. a first detector which comprises: a. first means for sensing the occurrence of the predetermined phenomena and generating a signal; b. first means responsive to said signal from said first sensing means for generating a local alarm to thereby indicate the occurrence of the phenomena; and c. first transmitting means electrically coupled and responsive to said signal from said first sending means to thereby wirelessly transmit a first signal indicative of the predetermined phenomena; and II. at least a second detector which comprises: a. second receiving means for receiving said first signal from said first transmitter and generating a signal; b. second means responsive to said signal from said second receiving means for generating a separate local alarm to thereby indicate the occurrence of the phenomena; and c. second transmitting means, responsive to said signal from said second receiving means, for wireless transmission of said first signal; and III. at least a third detector which comprises: a. third receiving means for receiving said first signal from either said first or second transmitting means and generating a signal; and b. third means electrically responsive to said signal generated by said third receiving means for generating a separate local alarm to thereby indicate the occurrence of the phenomena.
Claim 2
Dependent Claim
239 words
A detection system of the type intended to detect the occurrence of a local phenomena, and transmit at least one signal to other detectors to remotely sound an alarm, said system comprising: I. a first detector which comprises: a. first means for sensing the occurrence of the predetermined phenomena and generating a signal; b. first means responsive to said signal from said first sensing means for generating a local alarm to thereby indicate the occurrence of the phenomena; and c. first transmitting means electrically coupled and responsive to said signal from said first sending means to thereby wirelessly transmit a first signal indicative of the predetermined phenomena; and II. at least a second detector which comprises: a. second receiving means for receiving said first signal from said first transmitter and generating a signal; b. second means responsive to said signal from said second receiving means for generating a separate local alarm to thereby indicate the occurrence of the phenomena; and c. second transmitting means, responsive to said signal from said second receiving means, for wireless transmission of said first signal; and III. at least a third detector which comprises: a. third receiving means for receiving said first signal from either said first or second transmitting means and generating a signal; and b. third means electrically responsive to said signal generated by said third receiving means for generating a separate local alarm to thereby indicate the occurrence of the phenomena.
Claim 3
Dependent Claim
31 words
A detection system as recited in claim 1 wherein said third detector further comprises third transmitting means responsive to said first signal to thereby transmit said first signal by wireless transmission.
Claim 4
Dependent Claim
91 words
A detection system as recited in claim 2 wherein said first, second and third detectors comprise first, second, and third master control system respectively; said master control system, wherever mentioned, being electrically coupled to said respective transmitter in said detector, wherever mentioned, to be capable to cause said transmitter to transmit a second wireless signal upon the termination of the local phenomena; said receiving means wherever mentioned, upon receiving said second signal, and in combination with said master control electrically coupled thereto, causing said generating means to terminate said local alarm.
Claim 5
Dependent Claim
40 words
A detection system as recited in claim 3 wherein said transmitting means, wherever mentioned, comprises a wireless radio transmitter; said receiving means, wherever mentioned, comprises a wireless radio receiver; said generating means, wherever mentioned, comprises an electrically operated local alarm.
Claim 6
Dependent Claim
31 words
A detection system as recited in claim 4 wherein said second and third detector further comprise second and third sensing means, each coupled to said respective transmitting means and master control.
Claim 7
Dependent Claim
18 words
A detection system as recited in claim 5 wherein said sensing means, wherever mentioned, comprises a smoke detector.
Claim 8
Dependent Claim
18 words
A detection system as recited in claim 5 wherein said sensing means, wherever mentioned, comprises a flame detector.
Claim 9
Dependent Claim
18 words
A detection system as recited in claim 5 wherein said sensing means, wherever mentioned, comprises a burglar alarm.
Claim 10
Dependent Claim
18 words
A detection system as recited in claim 5 wherein said sensing means, wherever mentioned, comprises a gas detector.
Claim 11
Dependent Claim
22 words
A detection system as recited in claims 6, 7, 8, or 9 wherein said first, second, and third detectors being battery operated.
Claim 12
Dependent Claim
54 words
A detection system as recited in claim 10 wherein said detectors each comprise a local test means for disconnecting said transmitter and receiver from said alarm and sensing means to cause said sensing means to operate to thereby provide a local test that said battery, said sensing means, and said alarm are locally operative.
