To acknowledge a latched alarm, press and hold the power button for 2 seconds then release
after which the XD One will confirm with an LED sequence: scrolling illumination of alarm
colour, followed by a scrolling green sequence.
Note: If an alarm is not acknowledged by the user, the XD One will remain latched with the
illuminated LED and audio warning indefinitely.
The XD One device will only re-alarm on increasing or continued particulate levels above the
permissible threshold, after the original alarm has been user acknowledged and self-cleared.
