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.
