ALLTEC-AWLD
ALLTEC-AWLD is an addressable water leak detector for critical areas such as under raised floors in data centers. It alarms when water touches the sensing cable and maps leak distance in meters to zone names.
ALLTEC-SWLD
ALLTEC-SWLD is a single-zone water leak detector for high-risk and unseen areas. When water touches the sensing cable, it raises an alarm immediately to help protect electronic and IT equipment.
