Alarm console controls
First Claim
1. 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.

Abstract
An alarm console is provided which selectively generates audio signals in an ordered priority basis when there is a simultaneous request for two or more tone signals. The priority is from voice paging, highest priority; test mode, to test individually selected alarm tones; keyboard tone selection; automatic priority tone in response to a detected condition; automatic non-priority signal tone in response to a detected condition; and a lowest priority signal which typically comprises background music.
