EN / CZone® DDS User & Installation Manual
6 Bilge Pump Monitoring
The CZone DDS has advanced bilge pump functionality on all relay output channels. This allows pump control and
external (automatic) voltage detection from a single wire. CZone status indicators will illuminate if an external voltage is
detected from automatic float switches or CZone can trigger system alarms to notify owners of automatic bilge pump
operation, and optionally use this run signal to turn on other circuits, like additional pumps. You can track total run time
of pumps and display the information on CZone Display Interfaces. Delays can be configured to the ‘External Systems
On Alarm’ to stop nuisance alarm tripping from a float switch.
