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 60 on page 265 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 group, and an “in-suite” correlation group. The
following tables show the inputs and outputs for these groups.
To create correlations for in suite signal silence:
1. Create a set of correlations for each floor.
2. Create a single hallway correlation to control hallway sounders on all floors.
3. Create a single in-suite correlation for all floors to turn off sounders inside
dwelling units on all floors except the floor of alarm.
Details of each step are described below.
Creating a set of correlations for each floor
Referring to the tables below, create a set of correlations — one for each floor.
While the example given here is for a five-story building, you can adapt it to fit the
number of separate floors (or other areas) in your application. Create one
correlation for each floor (or area). These correlations ensure that if an alarm is
detected on the floor, sounders located in dwelling units on the same floor will
sound.
On each floor, link all input devices on the floor (both inside dwelling units and in
hallways) to the sounders inside dwelling units on the same floor.
Notes
• Set the alarm activation count for each floor correlation to 1.
