One thing to be aware of however is that this setting doesn't take effect until the board has booted, so whenever you restart it the alarm will sound for a few seconds until it's finished booting.
That's really helpful - thanks. Would be good to avoid any external relays of not needed . My existing setup has the same behaviour - alarm sounds briefly when booting. Not really too much of an issue.
