UE-04
Two-zone quick closing gate valve and HRD extinguishing system control unit
The UE-04 signaling and central control unit is used for activating both explosion-related decoupling systems and explosion suppression systems. In the former, the quick-closing gate valves in the pipelines prevent the spread of explosions. In the latter, the immediate use extinguisher suppresses the explosions even as they start. Both protection devices are controlled via the release circuits. The UE-04 has two monitored signaling lines that can be switched in two-line dependency for activation of both release lines and one for the monitoring circuit.
The device is compatible in either two- or four-wire technology with all Brandtronik sensors and with a large number of third-party manufacturers. It has relay outputs for malfunction, pre-alarm, alarm and two monitored outputs for release. For asymmetrical ground faults there is also ground fault monitoring. Along with the control elements for the quick closing gate valves there is also an LED status display on the front plate.

UV-
FALME DETECTOR
Ultraviolet flame detectors detect both open flame and arc fires and are particularly suitable for use in potentially explosive atmospheres.
IR-
FALME DETECTOR
The infrared flame detector detects open flames and fires of both organic and inorganic materials and is well suited to flame detection.
UV-
SPARK DETECTOR
The infrared spark detector detects sparks and flames in closed systems, such as absolutely dark system parts with very little extraneous light incidence.
IR/UV-COMBI-FLAME DETECTOR
The IR/UV combination flame detector detects fires with an open flame involving carbon. This is well suited for open flames without smoke development.
