The input point has a 10K pull - up resistor and is input in a 5V TTL level mode. For stable system operation, it is recommended to input dry - contact signals.
(4) Door 3 Unlock Output, Button, and Door Magnet Input Interface
Refer to (3) for the unlock output, button, and door magnet input interfaces of Door 3.
(5) Door 2 Unlock Output, Button, and Door Magnet Input Interface
Refer to (3) for the unlock output, button, and door magnet input interfaces of Door 2.
(6) Door 1 Unlock Output, Button, and Door Magnet Input Interface
Refer to (3) for the unlock output, button, and door magnet input interfaces of Door 1.
(7) Alarm Signal Output Interface for Door 1 and Door 2
Refer to (3) for the alarm signal output interfaces of Door 1 and Door 2.
As shown in Figure 2, NC4 - COM4 - NO4 are the alarm signal output interfaces for Door 4. NC4 - COM4 is a normally - closed output, which opens during an alarm, while NO4 - COM4 is a normally - open output, which closes during an alarm. NC3 - COM3 - NO3 are the alarm signal output interfaces for Door 3, with the same function.
(8) Alarm Signal Output Interface for Door 1 and Door 2
Refer to (7) for the alarm signal output interfaces of Door 3 and Door 4.

3. Installation Specifications and Precautions
When using the equipment, the following installation specifications and precautions should be followed:
1,The power cable and signal cable should be in separate conduits. When the two conduits are arranged in parallel over a long distance, the distance between them should be more than 30 cm (when using metal conduits for wiring).
2,The 220V AC power is uniformly supplied from the management center's UPS to each access control point. For small - scale systems, 220V AC power can also be taken nearby, but it must comply with relevant regulations.
3,When wiring, be sure to mark the wires, and the wire joints must be placed in the junction box to avoid trouble during future installation and debugging.
4,A straight - through cable of Category 5e or Category 6 (model: UTP CAT5e or CAT6) should be used between the access control controller and the switch. During construction, an information point must be reserved near the access control controller for network connection.
5,Installation requirements: The controller is generally installed in the weak current well or on the ceiling 30 cm above the door. If the access control controller is installed in a cabinet (it is recommended to fix the circuit board with studs, and the height of the studs should be ≥1 cm), it should be installed in a safe and reasonable position near the access control point. At the same time, considering the wiring specifications for the access control cabinet, before wiring, install gaskets or bushings at all inlet ports in accordance with the specification requirements (to prevent the cabinet from damaging the wires). The installation diagram is as follows:
(Here should be the description or reference of the installation diagram, but it's not shown completely in the original text, so it's hard to translate accurately. If there is an actual picture, more accurate translation can be made.)

6,Installation process and finished product protection: The access control controller is a core device of the system. Before installing the equipment, fully consider whether the site has the installation conditions, reasonably arrange the construction process, minimize cross - contamination. After the equipment installation is completed, do a good job in finished product protection measures to minimize and avoid contamination and damage to the finished product during the construction process. Before power - on, ensure that all wiring is correct, otherwise it may cause equipment damage.
