Planning Instructions Fire alarm system EBL512 G3, V1.1.x
Alert Annunciation
In some installations the Alert Annunciation function can be used to
avoid unwanted false alarms (nuisance alarms) to the fire brigade. A
time channel can turn on/off this function.
Trained personnel are required on site to locate the fire (the room) and
take the correct measures/actions depending on if there is a fire or not.
Normally analog smoke detectors and zones with smoke detectors
only, come in question to be programmed (via WinG3) for alert
annunciation. Heat detectors and manual call points should normally
not come in question for Alert Annunciation. A manual call point can
only activate the AA function if there are no other fire alarms
activated in the system (i.e. the second fire alarm will turn off the AA
96
function)
.
The AA function is normally turned on (enabled) during daytime
working hours only. A time channel can turn on/off (enable / disable)
the AA function. When the AA function is turned on (enabled) it is
indicated by the LED Routing equipment "Fire brigade tx delay" on
the c.i.e. front. Normally only one time channel is used for this
function but two or more channels can be used. The AA function can,
as an alternative, be continuously "on".
NOTE! The AA function can be de-activated (turned off) via menu
H2/B10 and will then stay so until turned on (normal) again via menu
H2/B10.

Alert Annunciation function:
Indications, print-outs, actions, etc. for an AA alarm are the same as
for a normal fire alarm except the output "Fire alarm" for routing
equipment (fire brigade tx) in each c.i.e. that will not be activated
97
directly.

Using an internal time channel is a VdS violation.
96
This is valid even if "Multiple alarms within same zone" is selected (via
WinG3).
97
NOTE! Programmable outputs type "Fire brigade tx" will however be
activated if not the following is added to the control expression: AND NOT
Alert Annunciation Activated.
