Kohler Comprehensive Guide to Remote Annunciators and Generator Monitoring Systems

6.1.11 Remote Serial Annunciator

RSA II is an annunciator panel offered in several kit configurations to support Kohler power equipment. The RSA is a remote serial annunciator Figure 6-18 and Figure 6-19 that monitors the condition of the generator set and/or ATS from a remote location. The RSA 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 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 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 6-20 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. See Figure 6-21 to Figure 6-25 for RSA wiring connections.

If the RSA II 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.
