CRelay Outputs
The relay outputs will withstand up to 5 amps at
30 Vdc (resistive load only). They can be used to activate horns and strobes. Refer to Figure 7 for proper wiring. Each relay can be configured in the
PROGRAMMING MENU.
Default setting is:
Relay 1 (J25) = Warn
Relay 2 (J26) = Alarm
Relay 3 (J3) = High Alarm
Relay 4 (J7) = Fault
Relay rating: 5 A, 30 Vdc (resistive load)

DJumper Instructions
The different jumpers on the PCB enable the user to make different operations manually.
Jumper EOL1, EOL2, EOL3, EOL4: Enable the user to add an
Jumper SHDN: This jumper enables the user to reset or shut down the microcontroller temporarily. It is mainly used during minor modifications in the wirings of the system.
Jumper RELAY J29, J30, J31, and J32: They are used to test the relay. Short pins to test.
