The display will cycle through all sensors that are signaling warning levels, at five seconds per display. Pressing any
key (except HUSH) will advance the display to the next sensor that is signaling a warning level.
If the buzzer and/or an external horn and/or external strobe are connected and configured to signal a warning
condition, they will also sound when a warning condition occurs. There is a configurable delay before the horn or
strobe will sound, see sections

When the HUSH key is pressed, the internal buzzer will be silenced for fifteen (15) minutes. If the horn or strobe turn
on delays have not finished, then they will also be silenced. If the delays have finished, the HUSH key must be held
for three (3) seconds in order to silence the horn and strobe.
When all indicators have been silenced, the display will show that warnings have been silenced for fifteen minutes.
After any key is pressed (or five seconds) the display will return to normal mode.
