Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
197 words
A warning alarm system comprising a pair of different visual signals, p1 audible signal means having a pair of different delivered signals corresponding respectively to each of the visual signals and having speaker means for delivery of said audible signals, signal input means responsive to a plurality of conditions, control means for said visual signals and said audible signal means responsive to one condition for maintaining said visual and audible signals in an inactive condition and to different predetermined conditions of warning for selectively simultaneously initiating one of said visual signals and delivery of a corresponding audible signal through said speaker means for one condition of warning and for selectively simultaneously initiating a different one of said visual signals and delivery of a corresponding different audible signal through said speaker means, said control means including members for providing a priority of one of said audible signals over the other, auxiliary voice input means including a microphone selectively connected to said speaker means, said voice input means including members for cutting off audible alarm signals to said speaker means and connecting said microphone to said speaker means thereby overriding said audible signal means without overriding said visual signals.
Claim 2
Dependent Claim
197 words
A warning alarm system comprising a pair of different visual signals, p1 audible signal means having a pair of different delivered signals corresponding respectively to each of the visual signals and having speaker means for delivery of said audible signals, signal input means responsive to a plurality of conditions, control means for said visual signals and said audible signal means responsive to one condition for maintaining said visual and audible signals in an inactive condition and to different predetermined conditions of warning for selectively simultaneously initiating one of said visual signals and delivery of a corresponding audible signal through said speaker means for one condition of warning and for selectively simultaneously initiating a different one of said visual signals and delivery of a corresponding different audible signal through said speaker means, said control means including members for providing a priority of one of said audible signals over the other, auxiliary voice input means including a microphone selectively connected to said speaker means, said voice input means including members for cutting off audible alarm signals to said speaker means and connecting said microphone to said speaker means thereby overriding said audible signal means without overriding said visual signals.
Claim 3
Dependent Claim
17 words
A warning alarm system as defined in claim 1 in which said visual signals are circumferentially visible.
Claim 4
Dependent Claim
17 words
A warning alarm system as defined in claim 1 in which said visual signals are strobe lights.
Claim 5
Dependent Claim
17 words
A warning alarm system as defined in claim 1 in which said visual signals are rotary beacons.
Claim 6
Dependent Claim
21 words
A warning alarm system as defined in claim 1 in which said signal input means is responsive to different liquid levels.
Claim 7
Dependent Claim
37 words
A warning alarm system as defined in claim 1 in which said control means includes relays each controlled by an input signal and having contacts for selective delivery of a visual signal and a corresponding audible signal.
Claim 8
Dependent Claim
22 words
A warning alarm system as defined in claim 1 in which said control means includes a member for preventing simultaneous audible signals.
Claim 9
Dependent Claim
32 words
A warning alarm system as defined in claim 1 in which members are provided for mounting said speaker means, and said visual signals in contiguous relation for display of said visual signals.
