19.4.1 DESCRIPTION
The Alarm Relay I/O module (Figure 19-11) provides four electro-mechanical relay outputs. Each
output is used to indicate a factory pre-defined alarm condition as shown in Table 19-5 below. Each
electro-mechanical output has normally opened (NO), normally closed ( NC) and common (C)
connections at the terminal block. All signals to and from the Alarm Relay I/O interface directly with
the various modules within the system.
User configuration is not required for this I/O module.
The Alarm Relay I/O module is used in all standard RFL 9785 applications. It can also be used for
future expansion and can be mounted in a spare I/O slot, if available, or in an expansion chassis.
