For many reasons the type of automatic door should be chosen carefully. You do not want to install an automatic door that does not meet with requirements of the entrances volumes of traffic, type of pedestrian (able bodied or disabled) School children or the elderly or frail.
Low energy swing doors
require no safety sensors to be installed as it only requires gentle movement to open and close. If an impact occurs on a pedestrian the force would be low and not cause injury (less than 67 newton meters of force).
operate with higher forces and result in quicker opening and closing. Semi -Automatic operate with push pads and safety sensors so that if a door approaches a pedestrian the sensor prevents colliding with the person. A push pad on a busy street will prevent a door from constantly opening and closing when passers-by are detected by an activation sensor as in a fully automatic door.
Fully automatic doors
work at a faster speed, having a greater force to, operate them (up to 150n) Safety sensors scan the area in front of the door looking for pedestrians and obstructions. The safety sensors prevent impact of pedestrians and objects. Automatic swing door operators are rated for constant usage, suitable for high volume traffic Schools Colleges, Shopping Centres, Hospitals, Doctors Surgeries and Supermarkets.
