SE Controls at Fensterbau Frontale

REQUEST A QUOTE

This year’s Fensterbau Frontale exhibition, which runs from 21st – 24th March in Nuremberg, is a key event for SE Controls.


While the focus is firmly on their innovative and extensive range of actuators, facade engineering and window control solutions, they are also exhibiting key products from their comprehensive smoke control systems supported by animated displays, video demonstrations and functioning products.

Among the key products being displayed at the show are the SECO Ni 24 25 and SECO Ni 24 40 chain actuators; OS2 SHEVTEC Controller and 30A power supply unit (PSU); OSLoop Coordinator and compact Manual Control Point (MCP) units. An overview of each product is provided below. 

SECO Ni 24 25 chain actuators 


SE Controls’ compact SECO Ni 24 25 chain actuators are being displayed in both single and twin chain versions to show their versatility and suitability for use in environmental applications. The SECO Ni 24 25 actuators are CE marked, operate on a 24 Volt dc supply and have been tested to 15,000 cycles

SECO Ni 24 40 chain actuators


SE Controls’ compact SECO Ni 24 40 chain actuators are being displayed in both single and twin chain versions to show their versatility and suitability for use in both smoke control and environmental applications. The SECO Ni 24 40 actuators are CE marked, operate on a 24 Volt dc supply and have been tested to 15,000 cycles. They are also certified and tested in accordance with the harmonized EN12101-2 standard, making them suitable for use in smoke ventilation systems.

OS2 SHEVTEC Controller and 30A power supply unit (PSU)


The OS2 Controller is an intelligent 24V dc control system designed to drive 2-wire 24V DC actuators in both smoke control and environmental ventilation systems. 

Operating from a 230V ac 5A supply, the OS2 SHEVTEC Controller can deliver up to 8A, enabling it to drive 24V motorised actuators and magnetic catches and incorporates battery backup to allow effective operation if the mains supply should fail. The OS2 SHEVTEC Controller is CE Marked and tested in accordance with EN12101-10. The system can be expanded further by linking additional 30A PSUs together to accommodate large current requirements.

OSLoop Coordinator


The OSLoop Co-ordinator is a modular smoke control product that enables the centralised coordination and control up to 15 remotely mounted manual control points (MCPs), while also allowing larger systems to be created, controlling up to 64 MCPs, by linking multiple OSLoop Coordinators. 

The Coordinator controls power and data to the networked system, fully monitoring primary (mains) and secondary (battery) power supplies, while also intelligently monitoring system current requirements and determining how and when the MCPs require power to activate automatic opening vents (AOV).

Manual Control Point


The MCP is designed to allow the Fire & Rescue Service to manually override the smoke control system through a user-friendly interface. The design includes an open button and a close/reset button, which are accessed by lifting the clear front door. 

The MCP contains actuator switching circuitry that also monitors actuator cabling and circuitry for any faults, while providing fault monitoring and support for one or more smoke detectors and cabling.
