MO, EMG, FIRE, TAMPER interface wiring diagram
Instructions:
1. When the MO interface becomes a short circuit, the elevator controller will cancel the control function
of the floor button. At this time, the elevator buttons can be operated manually. The "manual" function
can be canceled by directly changing the MO interface from short circuit to broken circuit.
2. When the EMG interface becomes short circuit, the elevator controller will cancel the key control of
each floor. To cancel the "emergency" function, please log in ZKBio CVSecurity software, click
[Elevator] > [Elevator Device] > [Real-time Monitoring] > [Emergency interface recovery button].
