Jablotron LD-81 flood detector
The Jablotron LD-81 detector works as an indicator of a room being flooded by water (e.g. cellars, bathrooms), wireless if connected to a JA-150M or JA-81M.
The detector works as an indicator of a room being flooded by water (e.g. cellars, bathrooms). This information is sent to an alarm system to send out an alert message. 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), see picture above. 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 does not need power as it takes its power supply from the JA-150M or JA-81M circuit.
It is possible to use the LD-81 with the JA-60N for Profi systems. You have to insert a 4k7 resistor in series with the LD-81 between the INP (red wire) input terminals and GND (black wire).
