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
