LD-81 flood detector
The detector indicates room water floods (e.g. cellars, bathrooms). This information is sent to an alarm system for alert message transmission.
It is possible to use the LD-81 with an older type of detector, the JA-60N, for Profi systems if you insert a 4k7 resistor in series with the LD-81 between the INP (red wire) input terminals and GND (black wire).
Operational temperature range
