I have just ordered an A16 to replace my wired ESP32-based alarm system (using home assistant and ESPHome).
My alarm bell box has a constant 12v supply, and activates the siren by pulling the trigger to ground:

Currently, I use low level outputs from the ESP32 board to trigger 5v relays to pull to ground.
If I am correct, the A16 outputs at 12v. In order to achieve the same result (pulling the siren trigger to ground) am I correct in thinking that I would need to replace the relays with ones that trigger at 12v?
Is anyone using the A16 already with a typical Bell box as the one shown?
