Buzzer activation and deactivation
AQ-S214 and AQ-S254 Alarming IEDs do not have an integrated buzzer. However, if an alarming
buzzer is needed it is possible to connect an external buzzer. I is activated by one of the output relays
of the IED. The user can set up the buzzer control by connecting the ALARM BUZZER signal to an
output (

BUZZER signal will also activate and the output contact can be controlled.
The user can silence the alarm buzzer by pressing the Back
Back button located in the IED panel, or by
connecting a digital input or some other binary signal in the logic to SILENCE ALARM BUZZER.
Clearing latched alarms

advised in order to keep alarm clearing simple.
