Evo-One E1 siren install

Question

How would I hook up my siren? It states pin E1 can be used as a + output option 1, or should I use the - horn output and choose option 4. Also, if using E1 does it reqiure a relay between it and the siren?

Answer 1

Use option 12 mode 2, thick white wire E1 will be siren +, don't need a relay.

If you already use E1 in your install, use horn output with a relay and use option 12 mode 4.
