2N3904 NTP transistor connection

[sensormatic1985]

Good night

I am trying to connect the NTE transistor but it does not arm or disarm my alarm panel DSC-585
of causality do they have an image where the connection of the NTP is shown? I am using an arduino uno board
another question, you have to enable some parameter in home assistast for the arming and disarming to work ?

I thank you very much
