If you have a Honeywell 5821 Temperature sensor and you want to monitor for flood conditions then the 470PB is the sensor for you. On this probe if water bridges the terminals for more than three minutes then it will set off an alarm condition at the panel. Very good to use in bathrooms, basements, etc.
