17.8.3
Reset of 2-zone / 2-address dependence (co-incidence alarm)
The unit / zone having activated a Co-incidence alarm will be latched in this status for at
least 5 minutes and then automatically reset. During these 5 minutes the push button
"Reset", on the CIE front, can be used to manually reset the Co-incidence alarm.
If, during these 5 minutes, at least one more unit (in the zone) or at least one more zone
(in the group) comes into "fire alarm state", the Co-incidence alarm ends and normal fire
alarms will be activated in the CIE

Delayed alarm
17.9.1
General time delay application
On some premises delayed fire alarm activation can be used to avoid nuisance alarms.
The delay time will be added at the end when a fire alarm normally would have been
activated in the CIE. This function is a violation to AS7240.2 standard
The delayed alarm function in the properties of analogue smoke detectors is called
"Delayed" while in conventional zone line input properties called "AVF". The functionality
of the delayed alarm in both types are different as explained below.
Each analogue detector in the system can be programmed (in EBLWin) to delayed fire
alarm activation, "Delayed" alarm check box in the detector properties must be ticked
. (Heat detectors should not and manual call points must not have delayed fire
alarm activation). The delay time can be set (in EBLWin, System Properties) to 0-255
seconds. In general applications, it is not recommended to use this function however if it is
necessary to be used, it has to be less than 30 seconds.
Function for an Analogue smoke detector:
An alarm point has to be in "fire alarm state"
to activate a fire alarm in the CIE. If an alarm point restores back to "normal state" during
the delay time, the delay time will reset and restarts when the alarm point activates "fire
alarm" again.
