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
___________________
STR- > STR-
S- > SRN-
12V > SRN+
0V > COM (also link made in bell box from 0V to TMPF)
TMPR > TAMP


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.
