The probe is mounted at the lowest point of the area to be monitored. The alarm is triggered when the probe comes into contact with liquid. The audible alarm can be muted with the Acknowledge button. The visual alarm remains active until the leak has been fixed. The Test button allows you to simulate an alarm condition in order to perform a function check. The self-monitoring probe triggers an alarm if it is damaged. The voltage-free relay contact is provided for connection of additional alarm equipment (such as additional alarm unit ZAG 01). ÖWWG 3 is suitable for panel mounting with a mounting frame. A sealing kit (IP 54) is available for rough application conditions. Alarm units can be integrated into your existing building automation systems at lug the wireless module into the interface (PCB of the device). The Gateway in conjunction with additional RIELS products with wireless technology allow you to configure a whole range of fully customisable, extensible features for the protection of plants and buildings.
