The RDA monitoring electronics can be easily integrated into the building surveillance.The system detects quickly and reliably even small quantities of liquid leaks. An optical and acoustic alarm signal is given. At the same time floating contacts are set for signals to the building services management and control tasks.The messages are saved until the reset via a push button or voltage disconnection. If the leak continues, the messages are lighting up again. The max. monitoring length is 1000 m. Up to 50 point sensors can be installed.
