ADU
Alarm Display Unit
The ADU (Alarm Display Unit) forms part of the RAM-
SYS product line. Compact and reliable, it has been
developed to display the measurements, alarms and
status of the monitors connected (Up to 32 with the
same RS485 interface). Through TOR data, it can also
manage visual and sound alarms of the processing
units (LMU, LPDU) connected with the ADU. Its con -
guration system allows to adapt the processing unit
working with the TOR data types of the monitor.
APPLICATIONS
• Barrier leak control
• Ef uent release monitoring
• Radioprotection of workers
• Operational process monitoring
• Post-accident operations
RELATED MONITORS
• LMU: Local Measurement Unit
• LP(D)U: Local Processing (and Display) Unit
FEATURES
● Can be connected anywhere to the network with the
RS485 links
● Con gurable according to needs
● Simpli ed maintenance
● Possible con guration with LMU and LP(D)U
● Ethernet connection
● Compact and light
