5. We connect the power through the power supply according to one of the given diagrams (installation colors and polarity are important)
To connect the calling panel on the back side there are:
- terminal block (No. 1 in the photo) for connecting to the intercom;
- RJ45 connector (No. 2 in the photo) for connection to an Ethernet network and power supply using Passive POE technology.

Important!
Power required is from 15 to 48 V DC. The SECRET MINI panel supports several power connection options:
- From the intercom calling panel, if there is a DC current of at least 15 V. - From an external power supply 18 - 48V.
- From an UNMANAGED POE injector (ST-2401, ST-4801). In this case, power will be supplied only if ALL 4 pairs of twisted pairs are used.
- If the facility has several calling panels connected via KM300 or KM500 switches, then each calling panel must have its own SECRET MINI connected.
