FAQ

Normal humidity will not trigger an alarm. Water leak sensors are designed to react only to contact with liquid water, not to air humidity.

Yes. Most water leakage sensors and detection cables can be reused after a drying check.

It is recommended to test remote water leak detection sensors monthly or quarterly, especially in critical environments such as data centers or industrial facilities.
