Leak and Humidity Alarm Relay
NVP is an electronic unit capable of detecting moisture and water leakage, and is designed to protect installations and materials against condensation and bursting water pipes.
NVP is a safe and reliable alarm system, developed for use in both large and small installations where there is a need for early warning of condensation or pipe bursts. NVP has proved a success in many homes and offices. It is used in the building trade to monitor attics and roof voids in order to keep roof leak damage to a minimum. It is also fitted in HVAC installations to monitor condensation in cooled ceilings as well as pipe bursts.
NVP was designed to provide customers with an advantageous combination of high quality, reliability and low life cycle costs.
- For use in both large and small installations

The alarm is activated in two ways:
- Sensor resistance to high – <900 kOhm (sensor loop interrupted)
- Sensor resistance to low (Max: <570 kOhm Min: <50 kOhm)

Contents of electrically conductive materials ( eg. rust, minerals, glycol) could be left behind on the sensor as it drys. Please change sensor.
Reply
Connection between terminal 5 and 7 is opened in case of an alarm.
Reply
Sensor + wire combined can be >50 m. Please do not install near high power cables!
