Recommended Solution:
Before laying of sensing cables, the site condition must be cleaned and vacuumed.
If not possible, at least the site is reasonably clear of debris and big objects, especially minimized
metallic burrs and objects.
Inform workers to be careful with those laid sensing cables, especially NOT to paint on it, step
and/or place heavy objects or equipment over the sensing cables.
Please make sure that the laid sensing cable can be physically access and check, in order to have a better
opportunity to eradicate the false alarms.
If after faithfully going through the above troubleshooting guides, the false alarms still cannot be
eradicated, please feel free to contact ELSA for further assistance and advice.
