Alarm output on RLN36 with motion detection

[user_687215746879682_687215746879682]

I have connected a siren to output 1+ 1- as indicated in the following diagram.
But when my Reolink ‎RLC-520A camera detects the intrusion alarm in our RLN36, the siren that we have connected to output 1+ 1- does not activate. As I must configure the software, so that when the camera detects the alarm (intrusion, movement, etc...), the siren that I have connected is activated.

@user_687215746879682_687215746879682 The alarm outputs on the NVR are simple relays (I think default to NO but you can set it to NC). They don't provide any power output. The connection diagram above is correct. Use power supply 12V 1A (max). By setting the IP Camera Alarm Schedule (under alarm output), you can associate the camera in the selected channel with the alarm-out channel.

@joseph_1979 Thanks for your replay, Joseph. You have said that the connection diagram above is correct, however you tell me to check out the article that have the same diagram connection plus the alarm device in. So I trying to activate the output relay without the alarm device in, just with the motion detection camara feature. Is it possible?

@user_687215746879682_687215746879682 I don't have the RLN36 but this is what I understood from the article. You can use the Alarm In to connect say a PIR, door contact, etc and then associate this Alarm In channel to any of the four Alarm Out channel (which can be the siren). The documentation is not so clear either.

Be careful not to apply high voltage as otherwise you will screw the circuitry handling the external alarms. It's an open collector transistor.
