When individual acknowledge is used, the tone-alert re-sounds when the condition clears.
Individual acknowledge must be selected if the panel is providing proprietary receiving service in

unacknowledged trouble condition. Continue pressing the TROUBLE ACK key and reading
the reports until all reports have been acknowledged. Once all reports have been acknowledged

flashes and the tone-alert sounds steady.
