Kaadas KA251-Z, Installation Manual

Master PIN code: 

Required for programming and feature settings, the 
Master PIN Code can be used to unlock the door while 
in vacation mode. The default Master PIN Code needs 
to be changed before programming the lock for 
security reasons.

Auto Lock:

If the Auto Lock is enabled, the lock will lock the door 
30 seconds after it has been unlocked. This feature is 

off by default. You can set the time delay for 30s, 60s,

120s and 180s in Master Mode.

Vacation Mode: 

This is a safety feature for you when you leave your house 
for vacation or a long trip. When you activate Away Mode, 
all User PIN Codes will be locked until the Master PIN Code 
is entered on the keypad. When the lock is unlocked by the 
thumb turn or key, an alarm will sound for 1 minute. By 
entering the Master PIN Code on the keypad, you can disable 
the alarm and Vacation Mode.

One-Time PIN Code:

You can add the One-Time PIN Code in Master Mode in 
advance. When the need arises, you can send the One-Time

PIN Code to visitors or friends. This code can only be used 
once and is automatically deleted when used.

Wrong Entry PIN Code Limit：

After 10 attempts of entering an invalid User PIN Code, 
the unit will shut down for 3 minutes.

Silent Mode:

The keypad will beep when pushed but can be muted. 
Low battery and Wrong Entry PIN Code Limit alarms 
will still sound in Silent Mode.
