Opening And Locking Systems
For natural smoke and heat exhaust ventilation and for ventilation
RWA 100 NT, RWA 105 NT and RWA 110 NT are opening and locking systems for RWA. They are suitable for daily room ventilation, for smoke and
heat extraction systems (RWA) and as natural smoke and heat exhaust ventilator (SHEV). Due to the mechanical locking it is not necessary to use
additional electrical locking drives. The systems consist of a mechanical bracket set combined with the high-quality RWA electric spindle drive
E 250 NT.
RWA 100 NT: RWA system for bottom-hung, top-hung and side-hung windows

• Use as RWA (24 V), in SHEVs in accordance with DIN 12101-2 and for natural ventilation (230 V in conjunction with a power supply or OL 350 EN)
• Available in four stroke lengths for all standard vertically installed types of casement
• Mechanical locking on the primary closing edge, with the option of using a mechanical additional locking device on the secondary closing edge
• Large opening widths with small spindle stroke in less than 60 seconds
• Synchronic mode on wide casements by using two RWA 100 NTs
RWA 105 NT: RWA system for post-rail-constructions
• Combination of an E 250 NT electric spindle drive flush-mounted on the frame profile and
a mechanical bracket set with double locking

(230 V in conjunction with a power supply or OL 370 EN)
• Available in three stroke lengths for vertically installed, inward-opening casements
• Double mechanical locking for burglar resistance and for high tightness
• Large opening widths with small spindle stroke in less than 60 seconds
• Synchronic mode on large casements by using the RWA 105 NT Syncro set
RWA 110 NT: RWA system for bottom-hung, top-hung and side-hung windows,
outward opening
• Combination of an E 250 NT electric spindle drive flush-mounted on the frame profile in
leaf installation and a mechanical bracket set with locking
• Use as RWA (24 V), in SHEVs in accordance with DIN 12101-2 and for natural ventilation
(230 V in conjunction with a power supply or OL 360 EN)
• Available in three stroke lengths for all standard vertically installed types of casement
• Mechanical locking on the primary closing edge
• Large opening widths with small spindle stroke in less than 60 seconds
• Synchronic mode on wide casements by using two RWA 110 NT
Electromagnetic RWA Systems
RWA EM “OPEN”: simple solution for opening pure RWA windows
• Secure locking of the windows through electromagnetic locking
• The magnetic primary lock and mechanical secondary lock keep the window leaf
securely closed against the pushing off force of the spring arms and the pressure of the wind.
• For leaf widths of 300 – 1000 mm (top-hung casements) and 1200 mm (bottom-hung casements)
the locking occurs via the magnetic primary lock
• For leaf widths up to 2000 mm (top-hung casements) and up to 2400 mm (bottom-hung
casements) the locking occurs via a magnetic primary lock, a connecting link arm and a
secondary lock
• Retrofitting with minimum effort
Electric Linear Drives
For use in conjunction with slimline fanlight openers
E 212: for use in conjunction with slimline fanlight openers
• For automating the fanlight openers OL 320, OL 90 N and OL 95
• Cost-effective and simple motorised solutions for actuating several scissors
• Natural ventilation, smoke and heat extraction system (RWA) in the 24 V version
• The narrow design allows unobtrusive adaptation to the appearance of window frontages
• The assembly group is completely preassembled, the limit switch and drive protection are already installed and adjustable
• Stroke with variable adjustment so that the opening width can be flexibly controlled on site
Fresh Air Systems
Optimum interaction of fresh and exhaust air openings
Adequately dimensioned fresh air areas are always required for safe, reliable functioning of natural smoke and heat exhaust ventilation. Cold air
flows in via the fresh air areas in the lower part of the building so that – due to the stack effect – any existing smoke rises and can be drawn out
through the extraction areas in the upper part of the building.
RWA TÖ: RWA control unit in combination with inversely mounted door closer
• With the RWA TÖ doors can be used as an RWA fresh air supply or smoke extraction
opening
• Simple system for creating large fresh air supply areas
• Released by the emergency power control unit, in the event of an RWA case the door is
opened by the force of the inversely mounted door closer
• In conjunction with the RWA TÖ system the door can also be used as a smoke extraction
opening
• Combination with the emergency exit system (RWS) enables its use on emergency
exits
RWA K 600: retractable arm drive for opening doors and windows
• Universal use on windows and doors, on the hinge and on the opposite hinge side
• Enables opening angles of over 90 degrees at windows and doors
• Use as RWA (24 V), in SHEVs in accordance with DIN 12101-2 and for natural ventilation (230 V in conjunction with a power supply)
• The integrated control enables synchronised multiple operation and door closing selection without an additional module
• Integrated status contact for direct connection of a door opener
RWA AUT: automatic opening of the doors in RWA case
• Use for automatically passable doors which, depending on their location in the building, are used as fresh air or exhaust air openings in case of an emergency.
• Due to the large opening widths of the automatic doors, large fresh air supply areas can be created
• Safeguarding the automatic door in accordance with DIN 18650 ensures comfort, convenience and safety
• Combination with the emergency exit system (RWS) enables its use on emergency exits
RWA Control Units
Central control units for control of individual components
Emergency power control units enable the coordinated actuation and release of fresh air supply and exhaust air openings, which are equipped
with electromotive drives. Release in case of fire occurs through automatic smoke detectors, manual RWA buttons or external alarm signalling
devices. Vent switches enable drives on the windows and smoke extraction openings to be controlled for normal ventilation.
