US4571586A — Alarm console controls

Claim 1

Independent Claim 254 words

A priority alarm, paging and signalling system arranged in a predetermined hierarchy with each level of alarm paging and signalling causing termination of any lower priority alarm paging and signalling signal, said system comprising in cooperative combination: (a) a console control station including a three wire output that may be used to control a plurality of remote sound generating and reproducing stations, and an alarm tone generator for selectively generating any one of a plurality of tone signals: (b) a remote input unit having a plurality of input control leads and with said coupled to the output of a remote control unit the output of said remote input unit is coupled to the input of said tone generator for activating said tone generator to generate a selective one of said plurality of tone signals in response to a signal on a corresponding selected one of said plurality of input control leads; (c) a keyboard control unit coupled to said tone generator unit for activating said tone generator to generate a unique one of said plurality of tone signals in response to activation of a corresponding unique key of said keyboard control unit; (d) disable means coupled between said keyboard control unit and said remote control unit to give one of said keyboard or remote control units priority over the other when both are simultaneously activated; (e) voice paging means; (f) an audio amplifier; and (g) first coupling means for selectively coupling said voice paging means or said alarm tone generator to said audio amplifier.

Claim 2

Dependent Claim 254 words

A priority alarm, paging and signalling system arranged in a predetermined hierarchy with each level of alarm paging and signalling causing termination of any lower priority alarm paging and signalling signal, said system comprising in cooperative combination: (a) a console control station including a three wire output that may be used to control a plurality of remote sound generating and reproducing stations, and an alarm tone generator for selectively generating any one of a plurality of tone signals: (b) a remote input unit having a plurality of input control leads and with said coupled to the output of a remote control unit the output of said remote input unit is coupled to the input of said tone generator for activating said tone generator to generate a selective one of said plurality of tone signals in response to a signal on a corresponding selected one of said plurality of input control leads; (c) a keyboard control unit coupled to said tone generator unit for activating said tone generator to generate a unique one of said plurality of tone signals in response to activation of a corresponding unique key of said keyboard control unit; (d) disable means coupled between said keyboard control unit and said remote control unit to give one of said keyboard or remote control units priority over the other when both are simultaneously activated; (e) voice paging means; (f) an audio amplifier; and (g) first coupling means for selectively coupling said voice paging means or said alarm tone generator to said audio amplifier.

Claim 3

Dependent Claim 28 words

The combination as set forth in claim 1 and including audio reproducing means associated with said control station for audibly reproducing the tone signal amplified by audio amplifier.

Claim 4

Dependent Claim 33 words

The combination as set forth in claim 2 and including second coupling means which is activated to a first state, when said voice paging means is activated, for disconnecting said audio reproducing means.

Claim 5

Dependent Claim 33 words

The combination as set forth in claim 1 wherein said control station includes a priority output lead to which a unique signal is coupled in response to activation of said voice paging means.

Claim 6

Dependent Claim 33 words

The combination as set forth in claim 1 wherein said control station includes a priority output lead to which a unique signal is coupled in response to activation of said remote input unit.

Claim 7

Dependent Claim 38 words

The combination as set forth in claim 1 wherein said control station includes a priority output lead to which a unique signal is coupled in response to activation of said remote input unit of said keyboard control unit.

Claim 8

Dependent Claim 50 words

The combination as set forth in claim 1 wherein said control station includes a priority output lead to which a unique signal is coupled in response to activation of said remote input unit of any one of said remote input unit, said keyboard control unit or said voice paging means.

Claim 9

Dependent Claim 51 words

The combination as set forth in claim 1 and including a source of low priority audio signals for application to the output of said control station when no other signal is required in response to activation of any one of said remote input unit, said keyboard or said voice paging means.

Claim 10

Dependent Claim 45 words

The combination as set forth in claim 8 wherein in response to the use of said voice paging means said low priority audio signals, said keyboard, and said remote input unit are all disabled so they cannot control an audio output from said control station.

Claim 11

Dependent Claim 39 words

The combination as set forth in claim 1 and including a plurality of control stations with one having a higher priority than the others and including means for said higher priority station to disable the lower priority control stations.

Claim 12

Dependent Claim 58 words

The combination as set forth in claim 1 wherein one of said selected ones of said plurality of input control leads to said remote input unit has priority for causing said tone generator to generate an associated signal irrespective of the concomitant presence of a signal on any of the other of said plurality of input control leads.

Claim 13

Dependent Claim 31 words

The combination as set forth in claim 1 and including an output signal control circuit coupled to said remote input unit and said keyboard control unit for decoding input signals thereto.

Claim 14

Dependent Claim 23 words

The combination as set forth in claim 12 wherein the output of said output signal control circuit is coupled to said tone generator.

Claim 15

Dependent Claim 29 words

The combination as set forth in claim 1 wherein said keyboard control circuit may be selectively activated in either or an alarm sending mode or a system testing mode.

Claim 16

Dependent Claim 31 words

The combination as set forth in claim 14 and including mode means which is activated to a first state when said keyboard control circuit is activated in said alarm sending mode.

Claim 17

Dependent Claim 30 words

The combination as set forth in claim 14 and including test means which is activated to a first state when said keyboard control circuit is activated in said testing mode.
