Syncro ASM VDR datasheet
When any fire, faults, disablement or panel control operations take place, their details are passed to the VDR equipment over a RS485 2 core shielded cable connection.
The VDR interface uses NMEA 0183 standard message format. The messages will include detection device address, zone and event type, up to 82 characters total
The Syncro AS Marine panel does not monitor the link to the VDR, but sends a “heartbeat” message at 30 second intervals. This heartbeat message allows the VDR system to monitor and report any failures in the data connection
Consideration must be taken as to the loading on the main panel.
