Alert Annunciation Function

The alert annunciation function can be used to avoid nuisance alarms to the fire brigade (if
connected). The function is configured via EBLWin and normally analogue smoke detectors
and zones with smoke detectors, can be programmed for alert annunciation. Heat detectors
and manual call points should not normally be programmed for alert annunciation. A manual
call point can only activate the alert annunciation function if there are no other fire alarms
activated in the system.
The alert annunciation alarms have to be acknowledged within an acknowledgement time.
The acknowledged alarm should be verified and reset within an investigation time, else the
output(s) for fire brigade tx will be activated.
During acknowledgement and investigation time:
• The output for fire brigade tx will be activated if a normal fire alarm is activated by a
detector/zone not programmed for alert annunciation or if the alarm is activated by
a manual call point.
More than one alert annunciation alarm is allowed within the same zone, if the
•
"multiple alarms allowed within same zone", option is set via EBLWin.
• "Number of zones" can be set via EBLWin. Normally, only one zone with alert
annunciation alarm is allowed but up to four zones can be programmed.
Acknowledgement and reset of an alert annunciation alarm can be performed from the
display unit. A programmable output for indication and programmable inputs for acknowledge
or reset alert annunciation alarm can also be used. Acknowledge time and investigation time
are set in system properties in EBLWin. The acknowledgement time can be set to 0-120
seconds and the investigation time can be set to 0-9 minutes.
Note: The total delay time (acknowledgement time + investigation time) of a fire alarm must not
exceed 10 minutes.
The alert annunciation function is normally turned on during daytime, working hours only. A
time channel can turn on/off this function. When the alert annunciation function is turned on,
it is indicated by the time glass on the FDCIE front. Normally only one-time channel is used
for this function but two or more channels can be used. As an alternative, the alert
annunciation function can be continuously on.
Note: The alert annunciation function can be turned off via the menu in the FDCIE and will stay
off until turned on again via the same menu.

Buzzer

The unit is provided with a built-in buzzer that will sound (0.4/5 s) when an alert annunciation
alarm is activated. The buzzer will be silent when the acknowledge button is pressed or when
the alert annunciation alarm turns into a true fire alarm.
If the buzzer is programmed as "disabled" via EBLWin, it will never sound.
