Em4X Main Pcb Alarm Mappings - NewMar Commander II Series Manual

( For reference only. Actual system alarm mapping may vary)

7.4.2 EM4x Main PCB Alarm Mappings

Alarms can be mapped to any of the voltage free output relays fitted to the EM4x. Output states of either
Normally Open or Normally Closed can be selected (NO and NC states are for the de-energized relay). A
jumper is fitted to nominate the required output state, ensure the jumper is placed in the correct configuration
for installation requirements.
If an alarm is programmed for the relay to be normally energized (such as a low voltage alarm where loss of
power will put the alarm into its "active" state), then be sure to connect the remote wiring appropriately.
Table 2 lists alarm assignment for the EM4x controller as matches the relay outputs shown in
