Planning Instructions Fire alarm system EBL512 G3, V1.1.x

Delayed alarm

In some premises delayed fire alarm activation can be used to avoid
unwanted false alarms (nuisance alarms). The delay time will be
added at the end when a fire alarm normally would have been
activated in the c.i.e. This function is a violation to the EN54-2
standard.
Each analog or addressable detector, each addressable multipurpose
I/O unit (3361) monitored input (Z) and 8 zones expansion board
(4580) input in the system can be programmed (in WinG3) to delayed
fire alarm activation. (Heat detectors should not and manual call
points must not have delayed fire alarm activation). The delay time
can be set (in WinG3, System Properties) to 0-255 seconds.
Function for an analog or addressable smoke detector:
An alarm point has to be in "fire alarm state"
order to activate a fire alarm in the c.i.e. If an alarm point goes back
to "normal state" during the delay time, the delay time will be reset
and start again if/when the alarm point comes in "fire alarm state"
again.
Function for each addressable multipurpose I/O unit (3361) monitored
Input 0 (Z) and 8 zones expansion board (4580) input:
A zone in "fire alarm state" will be recorded in the c.i.e. but fire alarm
will not be activated. When the delay time has run out the zone will
be automatically reset and if it still is in "fire alarm state" a fire alarm
will now be activated in the c.i.e.
Alarm Verification Facility
In some premises AVF can be used to avoid unwanted false alarms
(nuisance alarms). Note, this function is a violation to the EN54-2
standard.
This function is valid for any zone line input but only in the
Australian and New Zealand convention respectively.
In these conventions the function "Delayed alarm" (see above) is not
valid.
The function "Delayed" is selected in the dialog box for the zone line
input respectively.
Function: A zone in "fire alarm state"
G3 but a fire alarm will not be activated. After 15 seconds the zone
will be automatically reset. If the zone comes in "fire alarm state"
again within 110 seconds a fire alarm will be activated in EBL512 G3,
else nothing will happen until the next time the zone is in "fire alarm
state" and so on.

Default is 0 seconds and a recommended delay time is < 30 seconds.
94
A zone with the AVF not selected would in this state activate a fire alarm
in EBL512 G3.
