5.4 Remote Serial Annunciator
RSA III is an annunciator panel offered in several kit
configurations to support Kohler power equipment. The
RSA III is a remote serial annunciator (Figure 5-13,
Figure 5-14, and Figure 5-15) that monitors the
condition of the generator set and/or ATS from a remote
location. The RSA III alerts the operator through visual
and audible signals using LED indication and a horn. An
alarm silence and lamp test switch are included.
The RSA III meets NFPA 110, Level 1 (2005)
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 fault inputs and identify
associated power system equipment.
An RSA III 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 III, one must be designated as the
master device to broadcast to additional RSA III
annunciators, designated as slave devices. Up to five
RSAIIIslavedevicescanbeusedwithanRSAIII
master device. All RSA III annunciators are factory set
as the master device, but can be changed to a slave
device using a PC and SiteTecht software that
connects to the RSA III front panel via a universal serial
bus (USB) connection.
Connect the RSA III to the RS-485 connections on
TB-10. See Section 1.3 and refer to the generator set
wiring diagram for connections. The communication
settings on the APM802 controller are factory-set for
communication with the RSA III. See Section 2.12.6,
Screen 6.5.2 Serial Link.
Refer to TT-1625 Remote Serial Annunciator (RSA III)
Kits for operation and installation instructions.
A PC with SiteTecht software is required to make
the RSA III functional. Use your SecurID to access
KOHLERnet, click on the TechTools button, and follow
the instructions to download the files. See TT-1625 and
refer to TP-6701 SiteTecht Software Operation Manual
for more information.
The RSA III kits include components for surface
mounting or flush mounting.
If the RSA III is used with an Ethernet communication
network, order Modbusr Ethernet converter
GM41143-KP2 and refer to TT-1405 Converters,
Connections, and Controller Setup for Network
Communication for system installation.

Figure 5-16 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.
If a fault occurs, the RSA III horn activates and the
corresponding LED illuminates.
