If there are Co-incidence alarms generated in other zones, the LEDs "Alarms queued" (L2)
are blinking and the Co-incidence alarms will be automatically scrolled (each 5
th
second).
If two or more zones or alarm points (zone / addresses) dependent on each other are in
alarm status at the same time, normal fire alarm (see above) will be activated in the system.
The co-incidence alarm function can be turned on / off via a time channel.
14.6
Delayed Alarm
Delayed alarm is an option that can be enabled via EBLWin for a specific alarm point. Two
applications for delayed alarm are shown below.
14.6.1
General Time Delay Applications
In some premises delayed fire alarm activation from analogue smoke detectors can be
used to avoid nuisance alarms. The delay time will be added at the end
normally would have been activated in the FDCIE.
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 and manual call points must not have delayed fire alarm activation). The
delay time interval can be set (in EBLWin, System Properties) to 0-255 seconds. In this
application, the time delay must be as short as possible (less than 30 seconds. In fact, if
the FT128 is connected to the brigade, it is not recommended to use this function.
The Delayed alarm will be activated when the delay time countdown has started and a
normal fire alarm will not be activated until the delay time has run out. No outputs will be
activated.
Function
An alarm point has to be in "fire alarm state" for the duration of the delay time, in order to
activate a fire alarm in the FDCIE. If an alarm point restores back to "normal state" during
the delay time, the delay time will reset and start again when the alarm point activates a
"fire alarm" again.
In case of a Delayed alarm, the following occurs:
•
The buzzer in FT128 sounds 0.8 se. each 5
th
sec. (0.8 / 5 sec.).
•
Output programmed for delayed alarm are activated
•
On the first row in the FT128 display, the presentation number (zone-address) is
shown (for the first delayed alarm)
•
On the second row, an alarm text is shown (if programmed).
Example:
D e l a y e d a l a r m d e t e c t o r Z Z / A A
Or
D e l a y e d a l a r m Z Z
If more than one Delayed alarm is activated, the LEDs “Alarms queued” (L2) will be blinking
and the delayed alarms will be automatically scrolled (every 5
th
second).

This function is added in EBLWin software version V2.1.2
45
Outputs programmed for General pre-warning and outputs programmed for the activated pre-warning(s).
