How to Set Up Wireless NO Contact for Gate Using Zamela RNP-01 and PEP-01/230?

Welcome.

I have a problem I need to make a wireless contracton for a gate (unfortunately there is no way to pull the cable).
The device is to send a signal to a receiver (about 30 metres away from the gate.
The receiver must have a NO voltage free contact.
I was thinking of the Zamela RNP-01 system as a transmitter and the PEP-01/230 as a receiver, but how to connect the contracton to the RNP as there the contacts are controlled by N 230 V.
I was also thinking of some kind of radio.

AI: What exactly contracton do you want to use (NO/NC, what voltage/current can it switch)?
NO contracton
AI: What power options do you have at the gate - is there 230V available, or just battery or low voltage?
Power supply for the gate 230 and probably 24 volts

The contract contact controls the coil of the relay at 24V and its contacts actuate the RNP-01 as a transmitter.
