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
