Typical circuits
The circuit diagrams that follow use the term zone to indicate
notification zones as defined in UL 864.
“Notification zone: An area covered by notification appliances
that are activated simultaneously.”
Figure 5-1 shows a typical application of the 3-IDC8/4 module
to support two notification zones. In this example, power is
being supplied from the EST3 rail, and the jumpers (JP1 through
JP4) are set accordingly.
It is also possible to create a similar application that uses
external power, supplied to NAC 1/2 IN and NAC 5/6 IN. Refer
to the 3-IDC8/4 installation sheet for wiring details and the
required jumper settings.
In Figure 5-1, both zones are configured with separate NAC
circuits for audible and visible appliances. NAC 1 and NAC 5
are programmed as visible device types, and NAC 2 and NAC 6
as audible device types. This means that the signal silence
function can be configured to silence only the horns.
Separating the visible and audible devices is optional and may
not be required for your project. Refer to the Genesis Signal
Master installation sheet for additional configurations and wiring
details.
