3-4.2. REMOTE EXPANSION MODULES. The following paragraphs contain
wiring information for the following types of REMs used in the Genesis II System:
•
GENII RMI Remote Module Interface
•
GENII AI REM Analogue Input Module
•
GENII AO REM Analogue Output Module
•
GENII DI REM Opto Isolated Digital Input Module
•
GENII DI REM Dry Contact Digital Input Module
•
GENII DO REM Relay Output Module
•
GENII CS REM Control Station Module
•
GENII MZS REM Multi Zone Station Module
•
GENII MP REM Multipoint Module.
The RMI functions as a bridge between the controller and the other REMs. Communication
between the controller and the RMI is by way of a ribbon cable connected to the controller’s
LEM/REM Connector. Communication between the RMI and the other REMs is by way of a
standard RS485 Comms cable network.
The method for connecting the modules to electrical power and to the RS485 Comms cable
system is similar for most of the different types of modules, except where otherwise noted.
The following two paragraphs provide detailed instructions for connecting electrical power and
the RS485 system, respectively.
3-4.2.1. REM Power Connections. Electrical power requirements and connections
for all remote expansion modules, except the RMI and MP REMs, are the same. Power
requirements and connection information for the RMI and MP REMs are explained in
Paragraphs 3-4.2.3 and 3-4.2.11 respectively. Information in this paragraph is for all other
REMs.
Power requirements are 24Vac,
±
10% at 50/60Hz. Refer to the appropriate paragraph
below for the physical location of the power connection block within each type of REM. At
the power connection block, the 24Vac power terminals are:
•
Terminal 1 = 24Vac Supply
•
Terminal 2 = 0Vac Supply
•
Terminal 3 = Earth
Terminal 3 is for the protection of the RS485 Comms circuitry and must be connected to a
good, electrically bonded earth. This may be the earth bus bar of the switchboard or the
point that connects the chassis of the equipment the module is located in. This connection
is independent of and in addition to the earthed AC Neutral at Terminal 2.
CAUTION
DO NOT CONNECT TERMINAL 3 TO TERMINAL 2.
