+--- Thread: Risco Nova 6 Siren/bellbox connection to SEM (/thread-4497.html)
- The Old Scholar - 08-13-2016
I have added a second bell box (Risco Nova 6) to my Comfort system via an existing SEM, but can\'t get it to work. I have made connections below and it is completely dead so I\'m presuming I\'ve done something stupid, but I can\'t see what.
Nova 6 > Comfort

I thought that perhaps 12V should link to 12VF on Comfort instead of SRN+, but that doesn\'t seem to work either.
What am I doing wrong? Any help would be appreciated.

The connections seem correct
SRN+ is the same signal as 12VF
Perhaps the Risco is dead?
If you supply 12V and 0V to the bellbox and connect S- to 0V the siren should sound

Thanks Chiu. Looks like the unit is dead.
