The RSA meets NFPA 110, Level 1 applications that
require remote controls and alarms be powered by a
storage battery such as the engine starting battery. AC
adaptor kit GM62466-KP1 is available when NFPA is not
required.
The front panel decals include areas that can be used to
identify user-selected
associated power system equipment.

Note: Circuit board GM 49791-2 is a gauge driver and is
not a communications circuit board.

An RSA annunciator can be used for a single generator
set or with a combination of a generator set and
automatic transfer switch. In systems using more than a
single RSA, one must be designated as the master
device to broadcast to additional RSA annunciators,
designated as slave devices. Up to five RSA slave
devices can be used with an RSA master device. All
RSA annunciators factory default to the master device,
but can be changed with RSA II setup software that can
be connected to the RSA front panel via a universal
serial bus (USB) connection.
The RSA 1000 can be connected with the RSA II
provided that the master remote annunciator is an
RSA II.
RSA II setup software is required to make the RSA II
functional. Use your SecurID to access KOHLERnet,
click on the TechTools button, and follow the instructions
to download the files. See RSA II Setup Software at the
end of this document.
The RSA kits include components for surface mounting
or flush mounting.
Figure 6-18 shows the status of the system ready LED,
generator set running LED, communication status LED,
common fault LED, common fault output, and horn for
each fault or status condition.
Figure 6-23 for RSA wiring connections.
If the RSA II is used with an Ethernet communication
network, order Modbusr
GM41143-KP2 and refer to TT-1405 Converters,
Connections, and Controller Setup for Network
Communication for system installation.
