The Neptune Systems Leak Detection Sensor LD-1 is a flat leak detection sensor that can be used with the FMM module. Plug this LD-1 sensor into the FMM and place it under the carpet near your aquarium. Upon contact with water, the LD-1 will immediately send an alert to your Apex. You can then instruct your Apex to take any additional desired actions.

Note: The LD-1 only works with the FMM and cannot be used with the ALD module.
