| Advantage | In the normal state, The door is NOT mechanically locked, and users can pull the door open in one-step, which is very convenient. | Disadvantage | In the normal state, The door is mechanically locked, and users should press a button firstly, then he can pull the door open. |
| Disadvantage | When the interlock is activated, the electromagnetic locks of all doors need to be energized for a long time to maintain the interlocking state. A long time of energized will easily cause the electromagnetic locks to overheat and thus be damaged | Advantage | When the interlock activated, no electromagnetic locks need to be energized, so electromagnetic locks get a longer service time. |
| Disadvantage | According to the building regulations, in case of fire, the building needs to be powered off.
