FU-01.1
Single range spark extinguishing system control
The FU-01.1 spark extinguishing system controls and monitors single-zone spark extinguishing systems for protection from machines, piping, and paint and powder coating cabins. The equipment includes two monitored signaling lines: one for the spark sensor, the other for monitoring the flow monitor. 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. There is an error message or alarm both with water flow without extinguishing, as well as with extinguishing without water flow.
