Functional principle
GGR revolving door for large diameters – – normal mode: In normal mode the leaves are fixed by electromagnets, to prevent them opening accidentally if they are bumped or subject to wind loads. The leaves can be swung outwards to provide an opening in the summer, for ventilation purposes or to allow long objects to pass through.
GRA-F revolving door for smaller diameters – normal mode: The GRA-F is used for diameters smaller than 2.4 m. The folding mechanism of the turnstile construction allows the leaves to be repositioned to open up the building in the summer, for ventilation purposes or to allow longer objects to be passed through.
GGR revolving door for large diameters – escape situation: Irrespective of whether the door is a 3 or 4-leaf model: following the emergency release the leaves can easily be folded back to open the escape route. This allows a large number of people to reach the open air within a short space of time.
GRA-F revolving door for smaller diameters – escape situation: The GRA-F also allows the building occupants to escape safely when the diameter of the revolving door is less than 2.4 m safe escape: the leaves can be fully folded back thus ensuring that the frequently prescribed minimum width of 1 m is achieved.

HM-F FT escape route sliding door
The first sliding door also to be approved as an escape door in the locked condition: in nighttime mode the HM-F FT escape route sliding door becomes a swing door with escape door security.
-
How a sliding door becomes a swing door
Sliding doors are used as barrier-free entrances for shopping centres, hotels and airports as well as hospitals, retirement homes and homes for the disabled. When combined with the appropriate technical equipment they can be used in escape routes in day mode. Up till now, sliding doors were not approved as escape doors when locked in nighttime mode. The GU group offers the first sliding door also to be approved as an escape door in the locked condition: In nighttime mode, the sliding door becomes a swing door with escape door security. The escape route sliding door HM-F FT therefore guarantees the availability of rescue routes while also securely closing the building – all in one door element without having to install another escape door. This gives architects and planners more freedom when designing prestigious entrances that must comply with the AutSchR (German directive governing automatic sliding doors in rescue routes), EltVTR (German directive governing electrical locking systems on doors in escape routes), and also DIN 18650 and EN 16005.
Advantages at a glance
- Sliding door during the day, swing door with escape door security in nighttime mode
- No separate escape door required
- Complies with AutSchR (German directive governing automatic sliding doors in rescue routes), EltVTR (German directive governing electrical locking systems on doors in escape routes), DIN 18650 and EN 16005
- Provides planning certainty as the consent of the building supervisory authority is not required in individual cases
-
Functional principle
Automatic/Exit operating mode: The movement sensors are active in Automatic or Exit operating mode. The door opens automatically when approached. Redundancy guarantees that the sliding door opens automatically in the escape direction.
Off/Night operating mode: The sliding door becomes a swing door with escape door security. The door is locked and the movement sensors are inactive – the door therefore no longer opens when approached. The sliding door is secured against being pushed open via the integrated sliding door locking system and against break-out by escape door strikes in the pivot hardware.
Off/Night operating mode – authorised access: The door can be unlocked by authorised persons via access control or push-buttons on the inside and accessed as a sliding door. Following access, the door locks automatically.
Off/Night operating mode – emergency: If the emergency push-button is pressed, or if triggered via the building control system, the escape door strikes are released. The side-hung panels can also be pushed open in the event of a power failure or in a panic situation.

Barrier-free fire and smoke protection doors
Important aspect of preventative fire safety concept: natural smoke and heat exhaust ventilation systems conduct combustion gases, dangerous oxides and thermal energy into the open air. Fire and smoke protection doors prevent the spread of smoke and fire. As certified smoke and heat exhaust ventilation system solutions they can be adapted precisely to the individual building situation thus ensuring that the escape and rescue routes remain smoke-free.
-
Automatic swing-door drives
Fire and smoke protection doors close automatically to prevent the spread of smoke and fire. During normal operation and in escape situations they must not cause an obstruction. The automatic swing-door drives of the GU group satisfy both requirements: they guarantee that the doors close automatically while offering comfort and barrier freedom.
The GU group automatic revolving door drives ensure secure closure yet allow comfortable access via the radar motion sensor, push-button or access control system. Approved panic locks and a touch bar guarantee that an unobstructed escape route can always be made available. Entrance doors in the facade can also make use of the benefits of the swing-door drive: when combined with a multi-point lock, burglar protection and escape route safety are equally possible.
Advantages at a glance
- Automation of fire and smoke protection doors
- Outer doors with burglar protection can be automated
- Escape route safety is guaranteed

Escape routes without obstacles
Motor-driven lock of series 19
The 19 series motor-driven lock is a self-locking system with panic function and is suited for use in fire protection, smoke protection and escape doors. Mechanical unlocking is possible at any time using a key and lever handle or push bar.
Swing door drive DTN 80
Fire and smoke protection doors must close securely and automatically in the event of a fire. However, a closed or difficult to open door is an obstacle. This is where swing-door drives are used, which open and close automatically, thus ensuring freedom of movement and security. The DTN 80 swing-door drive has a patented double-spring system. The second spring assembly activates just before the door reaches closing position – in other words, exactly when a higher closing force is required. This means that the door is guaranteed to close quietly and completely, even under difficult construction conditions which could include draught, excessive pressure or a multi-point lock system.

Tested and certified system solutions for smoke and heat exhaust ventilation
Secure escape doors are only one aspect of efficient escape and rescue route systems. Efficient smoke and heat exhaust ventilation systems are equally important – as fire and the associated build up of heat and smoke represents the greatest danger to persons and buildings. GU group offers complete SHEV systems as a one-stop service thus simplifying the planning and implementation according to the standards an integral part of the preventative fire protection concept for smoke-free escape and rescue routes.
-
The complete SHEV system as a one-stop service
The prerequisite for this is the perfect functioning of all system components. As is the case with the natural smoke and heat exhaust ventilation units of the GU group, the tested system solutions are precisely harmonised and adapted to the individual building situation. In addition to smoke exhaust and ventilation solutions for stairwells, GU group also offers intelligent drive and control systems for large projects, such as sports halls, foyers and shopping centres. In this regard architects can rely on comprehensive and competent planning.

Functional principle
Smoke generation without smoke and heat exhaust ventilation: If smoke and heat is not removed, the resulting accumulation of combustion gases and dangerous oxides put the health of the building occupants severely at risk. In addition, an excessive build up of heat can block emergency exits and escape routes and in the worst case cause the building to collapse.
Smoke emission with smoke and heat exhaust ventilation: A smoke and heat exhaust ventilation system removes smoke and heat by drawing it upwards. A low-smoke layer forms above the floor through which fleeing building occupants and rescue workers can move. This also reduces damage to the building by heat.
Controlled extraction: The removal of smoke is based on the principle of thermal uplift: supply air openings in the wall and exhaust air openings in the upper part of the wall or ceiling area ensure that smoke is removed in a reliable and controlled manner.
SHEV air supply – ELTRAL TA 60 door drive: Ensuring reliable functionality of smoke and heat exhaust ventilation systems: with the ELTRAL TA 60 door drive, doors in entrance areas can also be used as SHEV air supply.

Monitor and control escape and rescue routes
Control and monitor escape doors centrally: depending on the requirements of the building the system can be used to manage doors centrally or is seamlessly integrated into the overall building management.
-
From central door management through to building management system
Escape and rescue routes are not independent systems. They are for example linked to fire alarm systems, access control systems or the building control system. This is why GU group developed the GEMOS system: tailored to the requirements of the building, the system is used for central door management, or is seamlessly integrated via interfaces into the overall building management.
Centrally controlled, flexibly networked: escape door security and burglar protection, ventilation and fire protection, entrance, thoroughfare and exit: the tasks performed by doors are many and varied. With GEMOS, GU group ensures that these tasks can easily be managed and controlled. The management platform can be flexibly adapted to the building situation and therefore offers intelligent solutions from door management through to integration into the overall building management. The user-friendly interface also ensures straightforward and safe operation of complex safety-relevant facilities.
Advantages at a glance
- Central monitoring and control of escape doors
- Integration in building management possible
- Individually adapted to the size and purpose of the building
- Intelligent alarm management

Functional principle
Central escape door monitoring
All door statuses can be determined at a glance and managed in coordination with other systems such as fire alarm systems or access control – both individually or as a complete system.
No additional software: all operating tasks are carried out via individually modified web interfaces in MS Internet Explorer or Mozilla Firefox. No additional software is therefore required at the workstations.
Intuitive operation: the user-friendly interface ensures straightforward handling and makes statuses such as alarms, faults and messages clearly understandable.
Appropriate to situation: Different operating modes can be selected in GEMOS for all building systems: they can for example be synchronously switched to day mode, nighttime mode or alarm at the push of a button.
