Wiring 
In-suite signal silence applications in residential occupancy buildings require separate signal 
circuits for each floor area. In addition, each floor area requires separate circuits for: 
•  Audible devices located within-suites or dwelling units 
•  Audible devices not located within-suites or dwelling units 
Figure 61 above illustrates these requirements in a sample residential occupancy building with 
five floors. The illustration shows that: 
•  Separate audible signal circuits are provided for each floor 
•  Audible signal circuits 2, 4, 6, 8, and 10 are located inside dwelling units 
•  Audible signal circuits 1, 3, 5, 7, and 9 are located in hallways not within dwelling units. 
Correlations 
To enable in-suite auto signal silence, you need at least ‘N+2’ correlation groups, where N = 
the number of floor areas. You need: A correlation group for each floor, a hallway correlation
