Relay Outputs
Field wiring connections are made to the screw terminals on the relay PCBA. Eight relays are available;
each contains two type “C” contacts rated for 5A. The normally open (NO), common (C), and normally
closed (NC) terminals are labeled on the relay PCBA. Refer to Figure 1 for terminal locations. Refer to
Figure 5 for a typical beacon light connection diagram.
To ensure proper termination, ferrules should be crimped on the end of all input wires prior to
connecting the relay terminal blocks. The terminal blocks can accept No. 28–12 AWG
conductors.
Setting the Station Address
Each station connected to the Page/Party ® system cable requires a unique address. Valid address settings
are hexadecimal numbers 05 through FE. The address for each station is determined by the system
programming.
Two hexadecimal switches located on the MIM CPU Board set the station address. The address consists
of a low address setting and high address setting. Each switch contains 16 settings, labeled 0–F. The
MRM station’s address is determined by the high address setting followed by the low address setting.
For example, to assign an address of 05, the high address is set to 0 and the low address is set to 5.
