AEI DK-2890, User Manual

High Traffic Passage:

A short buffer time may be necessary for opening a door outward after pressing the egress button 

for those exits open to a high traffic passage. An egress button with short delay and warning beeps 

helps the user to pay attention to the people passing by to prevent hitting them when the door is 

pushed outward.

Emergency Exit:

Emergency Exit is not open to the public for daily use. It is for emergency case only. It is usually 

closed and watched by guards. The egress button of this keypad can be programmed to offer exit 

delay with warning beeps and even gives alarm output to trigger an alarm system when the door is 

forced to open or the door is open after the exit delay expired. It is an useful tool to get attention of 

the person on duty.

SUPER USER CODE

The door is un-locked while the function is enabled. The “Output 1” LED (Green) turns ON.

Do not

 forget to stop this function after use because the door is un-locked. Also, the system 

refuses the optional functions (3) & (4) while Override function comes into effect.
This feature is 

good for all the “Fail-safe electric locks”.

“Fail-secure electric lock”

 requires power to keep in un-locked condition. It takes high current 

all the time while the function comes into effect and 

may cause damage

 to it. This function is not 

recommended for Fail-secure electric lock.
