3M water leak detector general-purpose type WR-NA

[Features]
It can be used in combination with sensors and stickers according to the application. (The sensor alone cannot detect water leakage.)
If the installed water leakage sensor gets wet with water, a water leakage alarm will be issued. (Guard lamp (for each line), buzzer, non-voltage contact signal output (batch and for each line))
The detection sensitivity can be adjusted according to the sensor used and the liquid to be detected.
There is a self-diagnostic function to check the disconnection of the sensor and the detection circuit system.
After the water leakage alarm, when the water leakage is restored and the water adhering to the sensor is removed, the alarm state is canceled.

[Use]
Refueling room, around air conditioners, under pipes, etc. (buildings, factories, condominiums, etc.)
