Installation requirements
and G1M-RM The G1M and G1M-RM Genesis Signal Master modules can be
used to synchronize NACs consisting of Genesis appliances.
They can also be used to synchronize mixed NAC
Genesis and Enhanced Integrity appliances, but the first
appliance must be a Genesis device and the Genesis Signal
Master module must be mounted on this device.
G1M and G1M-RM Genesis Signal Master modules cannot be
used to synchronize NACs consisting of Enhanced Integrity
appliances.
Typical circuits
The circuit diagrams provided in this section use the term zone to indicate
notification zones as defined in UL 864 (an area that is covered by notification
appliances that are activated simultaneously).
Figure 20 on page 103 shows a typical application of the 3-IDC8/4 module for
supporting two notification zones. In this example, power is being supplied from
the SFS1-ELEC chassis electronics and the jumpers (JP1 through JP4) on the
module are set accordingly. Refer to the 3-IDC8/4 Traditional Zone I/O Module
Installation Sheet (P/N 270492) for additional information on the 3-IDC8/4.
It is also possible to create a similar application that uses external power,
supplied to NAC 1/2 IN and NAC 5/6 IN on the 3-IDC8/4. Refer to the 3-IDC8/4
installation sheet (P/N 270492) for wiring details and jumper settings.
In Figure 20, 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 sheets for
additional configurations and wiring details.
