What to do if Xtralis VESDA VLC-400 Smoke Alarm has a power supply failure?
If the power supply for your Xtralis Smoke Alarm has failed, first check the power supply and restore it. If the power supply is not indicating a fault, inspect the wiring. If the problem continues, contact your authorized Xtralis representative.
What to do if the filter is removed from Xtralis Smoke Alarm?
If the air filter has been removed from the Xtralis Smoke Alarm, replace the filter. If the problem continues, check the filter switch.
How to fix Xtralis VESDA VLC-400 Smoke Alarm filter approaching capacity?
If the air filter of your Xtralis Smoke Alarm is clogged or the dust count is approaching the maximum threshold, the filter should be replaced and the filter counter reset.
What causes urgent high airflow in Xtralis VESDA VLC-400 Smoke Alarm and how to fix it?
If the airflow in your Xtralis Smoke Alarm exceeds the urgent high threshold, inspect the pipe work for breakages or leaks and rectify them. Cracks or breaks in the pipe work render the system much less sensitive to smoke in the protected area. Then, perform a ‘Normalize Airflow’ via Xtralis VSC.
What to do if Xtralis Smoke Alarm shows minor high airflow?
If the airflow in your Xtralis Smoke Alarm has exceeded the ‘Minor High’ threshold, inspect pipe work for breakages or leaks and rectify. Cracks or breaks in the pipe work render the system much less sensitive to smoke in the protected area. Perform a ‘Normalize Airflow via Xtralis VSC.
How do I fix urgent low airflow on my Xtralis VESDA VLC-400?
If the airflow in the Xtralis Smoke Alarm is below the ‘Urgent Low’ threshold, inspect pipe work and sampling holes for blockages and rectify. Blocked pipe work renders the system much less sensitive to smoke in the protected area. Re-normalize if necessary by performing ’Normalize Airflow’ via Xtralis VSC.
What to do if Xtralis VESDA VLC-400 shows minor low airflow?
If the airflow in your Xtralis Smoke Alarm has dropped below the ‘Minor Low’ threshold, inspect pipe work and sampling holes for blockages and rectify them. Blocked pipe work renders the system much less sensitive to smoke in the protected area. Perform a ‘Normalize Airflow via Xtralis VSC.
How to acknowledge filter replacement in Xtralis VESDA VLC-400?
If the filter of your Xtralis Smoke Alarm has been removed and replaced but not acknowledged in the software, select the ‘Reset Filter Settings’ command from the ‘Device’ menu.
How to fix Xtralis Smoke Alarm zone setup after reverting to factory defaults?
If the detector configuration of your Xtralis Smoke Alarm has reverted to the factory defaults, run the ‘Accept Factory Defaults’ command from the Device Menu. If this fault continues contact your authorized Xtralis representative.
Why was AutoLearn aborted on my Xtralis VESDA VLC-400?
If AutoLearn has been cancelled before the end of the set period of your Xtralis Smoke Alarm, this may be due to a Fire condition being detected during the learning period. Inspect the Smoke trends using Xtralis VSC. Investigate and eliminate the causes and re-run AutoLearn, or set the alarm thresholds manually.
