LD-81 The 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 connectible to an Oasis alarm system via a JA-81M wireless detector.

LD-81 The flood detector

Plug it into the IN1 input terminal (red wire) and GND (black wire). If the detector is triggered (e.g. by a water), it sends a trigger signal. If the detector goes into a stand-by condition, it sends a non-triggered signal. The LD-81 takes its power supply from the JA-81M´s circuit.

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).
