I bought a batch of your FC-7012E video doorbell access control intercom, and now I have to consult the installation of the device, how many units can be connected to the host and extension of this model of device, what locks can be connected, and how to route the cables, what are the requirements for cables? What is the maximum distance between the indoor unit and the host?
1. FC-7012E video intercom access control system generally supports one indoor station for one door station. If you want one door station to connect to multiple indoor stations, you must add an expansion board (support up to 3 after expansion).
2. FC-7012E video intercom access control supports: bolt lock, magnetic lock, electric control lock, strike lock and silent lock.
3. When the FC-7012E is in the system wiring, please arrange and lay the wiring according to the requirements of the weak current engineering standards, set the metal pipe, use standard wires, and lay separately from the 220V high-voltage wires to prevent interference with the call and video quality of the FC-7012.
4. The maximum wiring length of FC-7012E video doorbell intercom system is 100 meters.
