I'm trying to hardwire my alarm siren to the spare DIN transformer that I got with my Ring Doorbell Pro2. It has terminals 1,2 3 & 4. To provide 24volts I need to use terminals 1 and 4 but which is + and which is - as this seems to matter when wiring a siren. Its not clear from the information printed on the transformer itself.

I bet it'll work fine. The polarity doesn't matter. It's only to power the LED light, the siren itself works from those big old Ever Readies ;)
