The New Generation of Automatic Door Systems
What we consider to be imperative – and what you can count on.
With its iMotion, TORMAX has opened a new chapter in door automation. The ground-breaking new generation of automatic door drives combine reliable, slimmed-down technology with value for money, respect for the environment and sustainability.
iMotion has a modular design. It consists of durable components, operates with minimum noise and is practically maintenance-free. We also considered the environment way back at the conceptual design stage – iMotion combines energy-saving technology with environmentally-friendly recyclable components. And if the requirements placed on the door should change over time, iMotion is far from redundant and thanks to its modular construction can be quickly and easily adapted to meet the new circumstances.
iMotion drive systems can be used anywhere. All systems are equipped with the same control systems and user interfaces – which significantly simplifies the maintenance and operation of all door types (sliding, swing, folding and revolving doors) both for interior and exterior use.

Safety and Security Mean Choosing the Right Door
In order to find the right door type which is the best possible fit with the requirements of both users and operators, it is advisable not only to consider the aesthetic requirements but also some other important aspects at an early stage. Much attention should be paid to personal safety. Use the following headings as a short check-list at the planning and design stage.
* building type (station, doctor’s office/surgery)
* door size
* door weight
* available space
* clearance
* exterior or interior rooms
* traffic flow
* frequency of use
* rush hours (main traffic times with increased peak usage)
* hold-open and closing times
* items which have to be moved
* trained staff
* the general public
* children
* persons with restricted motor functions (old or handicapped people)
* escape route
* fire protections
* anti-burglar requirements
* water-tight
* hermetically sealed (clean rooms)
* sound-proof
* Maximum energy is calculated as follows:
* Sliding doors E=(m*v2) /2
* Swing doors E=(J*ω2) /2
Dynamic forces must be limited such that injury is not possible.
* contactless sensor technology
* reduced speed
* deformable crush points
The EU Machinery Directive demands that risks must be avoided or removed, action taken against possible risk and users informed about residual risks. We recommend that you always undertake a risk assessment before commissioning an automatic door system.
Summary of the most significant danger points and their elimination
Main closing edge:
danger from crushing or collision
Minimisation of risk from the main closing edge:
crushing zone controlled by monitored presence sensors
Secondary closing edge:
danger from crushing or collision
Minimisation of risk from the secondary closing edge::
compliance with the safety distances Solution for smooth walls
1) < 8 mm against entrainment of fingers
2) < 100 mm is considered to be sufficiently reliable to prevent collisions (since DIN 18650:2010)
3) > 200 mm against crushing of the head
Main closing edge:
danger from crushing or collision when the door is opening and closing
Minimisation of risk from the main closing edge:
crushing zone controlled by protection sensor mounted on the door (1), safety distances (2/3) and monitored presence sensors (2)

Movement and presence
Multi-purpose technology is used for the combination of opening automatic doors and making them safe. These multi-purpose sensors also fulfil a large number of additional functions which can significantly increase the convenience of the door.
Advantages
* guarantees all-round safety for the user
* an activation and safety device
Radar movement sensors detect people in a fixed area. They are therefore ideal as opening activators for automatic doors.
Advantages
* penetrates foreign materials such as wood, plastic and plaster
* detects people and goods
* can be set to detect the direction of movement
* adjustable sensitivity
Disadvantages
* stationary objects are not detected
* sources of interference can cause malfunctions
* response sensitivity is dependent on the size, speed and angle of approach of the object
* imprecise detection range
After a short period of adjustment, passive infra-red movement sensors memorise the infra-red image they detect in the range for which they are configured. If this thermal image changes, the sensor creates a defined signal. Passive infra-red sensors are very reliable opening activators for automatic door systems.
Advantages
* very compact designs are possible
* can be set very accurately
* precise detection ranges
Disadvantages
* stationary objects are not detected
* goods without a temperature difference are not detected
* imprecise if the temperature difference between the object and the background is small
Active infra-red detectors consist of a transmitter and at least two receiver chips with high-performance optics. The receiver is able to recognise whether the infra-red light emitted from the transmitter is reflected by a person or object inside or outside the (background of) the scanning zone. In a modular construction system several beams can be allocated to lines or defined areas.
Active infra-red detectors are well suited for use as protection against crushing or cutting edges in revolving doors, sliding doors (replacements for protection leaves) and swing doors. The detectors can also be used as activation sensors for the door drive.
With background analysis
Advantages
* detection range can be set to 0 mm
* the transmitter can be tested
* detects reflective objects
Disadvantages
* background necessary
* dependent on the luminosity coefficient of the background
Without background analysis
Advantages
* no background necessary
* independent of the luminosity coefficient of the background
Disadvantages
* cannot detect persons/objects in very close proximity
Light beams are opto-electronic sensors which detect objects or persons by means of light. Light beams react to any interruption to the beam between the light transmitter and receiver. If an object is detected, the sensor creates a defined electric output signal.
Advantages
* reliable in use even in adverse ambient conditions
* very clearly defined trigger point
* few problems with reflective objects
Disadvantages
* cable to be installed in the door profile
* no surface protection
