Subject: Remote Serial Annunciator (RSA III) Kits (Firmware Version 1.0)
Introduction
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 1,
Figure 2, and Figure 3) 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 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.
Figure 1 Remote Serial Annunciator (RSA III)
An RSA III annunciator can be used for a single
generator set (Figure 1) or with a combination of a
generator set and automatic transfer switch(es)
(Figure 2 or Figure 3). 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 RSA III slave
devices can be used with an RSA III 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.
The RSA II can be connected with the RSA III provided
that the master remote annunciator is an RSA III.
