Safety

·         Lock up -  The door can find locking-up position automatically and lock up manually

·         Fire alarm -  KA023 automatic door has a pre-fixed, 3-chip signal wire as the fire-alarming control port.  When there is a fire alarm, the Panic Breakout comes into operation automatically enabling to push-and-go.

·         Anti-squeeze – When the anti-squeeze sensor on the mullion at the opening is touched, the door will stop immediately.

When the sensor at the entrance detects a pedestrian, the door will stop immediately.

·         Anti-strike -  When the anti-strike sensor at the wing’s bottom is touched, the door will stop immediately

·         Instant-reaction – When the resistance to the revolving wing is bigger than the preset parameter (adjustable), the door will stop immediately.

·         Disabled Access – Press the button to enable the door to revolve at low speed to facilitate the disabled

Operation

·         Continuous working mode

The door keeps revolving at low speed if no pedestrians.  The door revolves at normal speed if pedestrians are detected by infrared sensors and the mode will keep on until no pedestrians.  This mode is quite suitable for large traffic flow

·         Go/stop working mode

The door stops if no pedestrians (3 and 4 wing series have different stop positions).  The door revolves at normal speed if pedestrians are detected by infrared sensor and the mode will keep on until no pedestrians.  This mode is energy saving and offers better insulation

·         Remote control function

All down lights can be remote controlled.

Electronic & Mechanical Features

·         Advanced control system

KA023 applies the PLC and A/C inverter control system, which improves its steady operation with more functions and prolonged life.
