Safety feature 1
The door system conducts a self-test in every operation to check whether sensors are working to detect the protection area correctly.
Safety feature 2
Higher density of sensor area
Densifying the sensor area results in greater certainty of detection and better reaction to potential risks near the door, in order to prevent collisions between the door and pedestrians.
Safety feature 3
Trouble indication on sensor
If there is any trouble with the components including the sensors, the fail-safe mechanism works and the LED starts blinking to show “network component error” so that building owners can easily comprehend the current situation. In the case the sensor shows the LED blinking, please contact your local distributor of NABCO.
Safety feature 4
Self-diagnosis function allows the automatic door to monitor safety autonomously. If a problem occurs, it can be identified immediately and the fail-safe mechanism will work to prevent an accident.
Safety feature 5
Occurrence of trouble involving a component
Safety feature works (opening or stopping the door) to prevent an accident.
The door system judges pedestrian's movement and, after the pedestrian passes through the door, starts the closing action earlier, contributing to energy saving.
Since sensor detection spots can be set one by one according to the actual site environment, it is possible to reduce unnecessary door operation.
The interior environment is improved and operational efficiency is maintained.
Touchless switch mode
In case the door keeps opening unnecessarily due to continually passing by the door,
the setting can be changed to Touchless switch mode (only NS-A 01 / 02 / 03).
In the case of Touchless switch
mode, pedestrians walking or
objects moving pass the
passageway are not detected.

Employment of a resin-baked door roller and complete improvement of the door roller and rail offer improved safety and quietness.
The optimal design of the door roller and rail increases the antiderailing performance and ensures safety in case of a possible collision of a pedestrian/object with the door.
The flange design on one side is improved to increase the anti-derailing performance of the door.
To prevent derailing, the door
roller is equipped with an
anti-derailing mechanism as standard.

What is CAN (Controller Area Network)?
The CAN technology used in NATRUS is the ISO international standard network technology.
Since this technology offers high reliability, noise resistance and superior fault-detecting features in information communications, it has been widely used to transfer important information in various fields including transportation equipment such as automobiles, aircraft, railroad vehicles and ships; medical equipment; and industrial equipment.
