FU-01
Single range spark
extinguishing system control
The FU-01 single-zone spark extinguishing system control is used for the control and monitoring of single-zone spark systems for the protection of machines, pipelines, painting and powder coating cabins. The equipment includes two monitored signaling lines: one for the spark sensor, the other for the monitoring circuit. In addition the device has two monitored outputs for warning and extinguishing, as well as relay outputs for malfunction, alarm and system-off.
The detection of more sparks causes an automatic extinguishing time delay by a preset time span. With an overrun, the system is switched off and an alarm is started. DIP switches enable configuration for a wide spectrum of applications. Along with the control elements there is also an LED status display on the front plate.
