User Manual
The C5S access control panel is powered through a +12 V DC power supply or PoE, whichever can be chosen.
If you choose a +12 V DC power supply, generally, to reduce power interference between control panels, each
control panel should be powered separately.
If you choose PoE, the TCP/IP network interface of the access control panel can serve as a PoE interface and a PC
communication interface. The PoE switch must conform to IEEE802.3at standards.
To prevent power failure of a control panel from making the whole system unable to work normally, the access
control management system is usually required to have one UPS at least, and access control locks are powered
externally to guarantee the access control management system can still work normally during power failure.
