--AR-401-IO-1709R with special firmware of:
4 doors interlocking à 401RO8DI16_V0207_210621 DOOR_INTERLOCK_4.ISP
8 doors interlocking à 401RO8DI16_V0207_210621 DOOR_INTERLOCK_8.ISP
- Function:
Interlocking is a set of doors controlled by a programmed controller to deny second door access when first door remained opened. Suitable for prison or clean room with multi-group access over a space that shares interlocking solution
- Problem Solving:
One way interlocking solution for four doors or eight doors control, including fire alarm/emergency button to release all doors event when triggered.

A. 4 doors interlocking
A-1 Programming Logic
Door 1 open -> Door 2/3/4 cannot be opened
Door 2 open -> Door 1/3/4 cannot be opened
Door 3 open -> Door 1/2/4 cannot be opened
Door 4 open -> Door 1/2/3 cannot be opened
- Normal access: press push button to enter door
- If door 1/2/3/4 force open without normal access, will trigger alarm
- If one of the four doors is open, the second door could not be opened. Example: Door 1 is opened, normal access on door 2 will result in door 2 still remain as locked.
- All doors will be auto released when fire alarm event is triggered

B. 8 doors interlocking
B-1 Programming Logic
The same logic with 4 doors, the only different, there is no individual alarm output for each door.
Door 1 open -> Door 2/3/4/5/6/7/8 cannot be opened
Door 2 open -> Door 1/3/4/5/6/7/8 cannot be opened
Door 3 open -> Door 1/2/4/5/6/7/8 cannot be opened
Door 4 open -> Door 1/2/3/5/6/7/8 cannot be opened
Door 5 open -> Door 1/2/3/4/6/7/8 cannot be opened
Door 6 open -> Door 1/2/3/4/5/7/8 cannot be opened
Door 7 open -> Door 1/2/3/4/5/6/8 cannot be opened
Door 8 open -> Door 1/2/3/4/5/6/7cannot be opened
- Normal access: press push button to enter door
- If door 1/2/3/4/5/6/7/8 open without normal access, will trigger alarm (public alarm)
- If one of the doors is open, the second door could not be opened. Example: Door 1 is opened, normal access on door 2 will result in door 2 still remain as locked.
- All doors will be auto released when fire alarm event is triggered
