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. 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.
