How can i activate \"siren reverse\" on SEMS?
Thanks

Siren Revese is not applicable for Slaves
In fact it is rarely used even on the Main Comfort controller
Are you sure you need it?

Yes, i\'ve got 3 sirens, one wired to the maìn panel, one to sem 1 and one to sem 2.
For now i can use a relay to overcome the problem, but may be useful if the checkbox \"siren reverse\" will work even for SEM\'S
Thanks.

Can you use the connections shown in http://www.comfortforums.com/forum16/2288.html to connect to the siren on the slave?
Most sirens will work like that,

Thanks, already done this in main comfort panel.
For SEMS, i use a relay to simulate \"siren reverse\" option.
Don\'t worry.
