Operation
The EN54 PSU shall be fitted with a 'Fault' relay that is energised during normal operation and de-energised for
any fault condition. The 'FAULT I/P' connections on the sounder booster card should be connected to the 'COM'
and 'N/O' connections of the PSU as shown above. The table below indicates the state of the relay for all
conditions.
