One Siren for Multiple Areas

[sionxct]

I have an Elk M1 with two areas and a siren connected to output 2. I'd like the siren to trigger if either area goes into an alarm. However, what its doing now is only sounding the siren if area 1 goes into alarm. If area 2 goes into alarm, no siren. Is there an option I am missing? Do I need to set-up a rule to sound the siren if area 2 goes into alarm?

Not exactly sure why, but now the siren is sounding when either area goes into alarm. Thinking maybe a flaky siren or connection, and coincidence
