3.5.3.3 Door Open Alarm Setting 
Door Open Alarm 
(00-30):00 
[←] [↑] [↓] [→] 
  Default setting: ‘00’ 
The terminal checks how long the door is opened. This function issues an 
alarm if the door is opened for a duration that exceeds the time in setting 
(Min. 5seconds ~Max. 30 seconds). 
If it is set to ‘00’, an alarm is issued. Even if it is set to 01~04, an alarm is 
issued after at least 5 seconds are elapsed. 
The door should be locked within the time in setting but the door may not be 
locked due to unforeseen circumstances. In such a case, an alarm is issued to 
determine the cause of a problem and take the necessary measures to ensure 
normal door operation. 
To use this function, the lock must have a monitoring function that checks the 
opening/locking of the door. Also, the monitoring pin of the lock must be 
connected to the terminal. In addition, the door open state check in the 
previous item must be set to ‘1’ or ‘2’ in order to set this function. 
After selecting a setting value, press down [F4] button for a longer period of 
time to continue setting. Afterwards, all settings for the door are completed 
and the system moves to the upper menu.
