Safety feature 1

Self-test feature for sensors

The door system conducts a self-test in every operation to check whether sensors are working to detect the protection area correctly.

Self-test in each single opening/closing cycle secures safety always
In closing operation

Safety feature 2

Larger sensor spots offers safer entrance environment for all pedestrians.

Larger sensor spots offers safer entrance environment for all pedestrians

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

LED blinks to show occurrence of trouble

LED blinks to show occurrence of trouble

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

NABCO network system based on CAN communication

NABCO network system based on CAN communication

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

Fail-safe design

The door system detects the faulty component to provide optimal operation.

Occurrence of trouble involving a component

Safety feature works (opening or stopping the door) to prevent an accident.

The door system detects the faulty component to provide optimal operation.

For example:

  • If trouble with the geared motor is detected, the door is stopped.
  • If trouble with the sensor is detected, the door is full-opened.
  • If a wire break is detected, the door is stopped.

Various setup for comfortable environment
Smart settings meet user's requirements in broad occasions.

ECO mode

The door system judges pedestrian's movement and, after the pedestrian passes through the door, starts the closing action earlier, contributing to energy saving.

Spot-by-spot setup of sensor

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.

  • When a hand is placed near
    the touch plate, the door
    opens.

  • After the door opens, the
    detection area is enlarged
    around the door to detect
    pedestrians.

  • When no more pedestrians are
    detected, the door closes and
    the detection area returns to be
    limited again.

  • Touchless switch mode works by means of near infrared reflection of active infrared sensor.
  • Therefore, unlike a mechanical touch switch, this sensor may detect pedestrians or objects outside the detection area of the touch plate.

Long-life design and low running costs
Special design based on our abundant experience provides high durability.

Soft resin(polyurethane) Aluminum alloy

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.

Conventional door roller→NATRUS

Anti-derailing performance

Anti-derailing performance

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.
