A spot sensor rarely covers the area around a cooling unit or CDU, because water can escape at any point. This set monitors 5 m of sensing cable and connects to a WLD zone input via the 2 m AB connecting cable. According to the manufacturer, the system goes from first drops to alarm in 1-5 minutes.
Benefits
- Detection along the full length: a few drops of conductive liquid anywhere on the 5 m sensing section trigger an alarm.
- Thinner than Type A: the smaller diameter dries faster, and the cable can be cleaned, dried and reused.
- Tolerant installation: no bend radius and no twist limit, stepping on or pressing the cable causes no false alarm, and it can run under door thresholds.
- Mix with Type A: both types share the same 2-pin locking connector and can be combined in one zone.
- Extendable: non-sensing extension cables allow up to 185 m per zone.
