15.6 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.
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
45
when a fire
alarm 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 FT1020G3 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.
Example; Delayed alarm zone 123, address 45 (within zone 123):
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 sec. each 5
th
sec. (0.8 / 5 sec.).
• Outputs programmed for delayed alarm will be activated.
• In the FDCIE display, a presentation number (zone/address) is shown (for the first
delayed alarm). Also, a user definable text message (= the alarm text for fire
alarm) is shown (if programmed).
The presentation number is automatically followed by "SMOKE" depending on the type of
alarm point (i.e. SMOKE, HEAT, MULTI or MCP).
Note: The text "Menu" for the soft key "P5" is visible in the display, only if the door in
the CU is open.

This function was added in since EBLWin software version V2.1.2
SMOKE
User definable alarm text for 123-45.
