How to silence an alarm on the Trolex XD1+

In the event that a warning alarm is triggered, the XD1+ will auto-latch to ensure that
a conscious action is made to acknowledge the warning. During alarm state, users can acknowledge triggered alarms which will silence the audio alarm, however, the LED warning indication will remain illuminated (solid) to indicate the alarm conditions are still present.

It is only at the point of particulate level decrease to below the permissible threshold, 95% of the alarm set point, will the alarm reset and illuminated LED switch off.

To acknowledge a latched alarm, press, hold and release the power button after 2 seconds which will confirm response via 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 XD1+ will remain latched with the illuminated LED and audio warning indefinitely.

The XD1+ 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.
