C Relay 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)

D Jumper 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 END-OF-LINE jumper to improve
the communication signal. Two positions are
possible, R or RC. It can vary in accordance with
the system constraints. See the wiring detail for
the EOL position.
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.
