Pre-warning detector 12- 45
(user definable text message)
Example; pre-warning zone 12:
Pre-warning zone 12
(user definable text message)
LEDs "Alarms queued" (L2) blinking are indicating more than one pre-warning and they
will be automatically scrolled (each 5th second). Pre-warning is automatically reset see
chapter "Alarm reset", page 58.
14.2 Fire Alarm
256 alarms (points or zones) can be presented in the FT128 display.
The following occurs in case of a fire alarm:
• The buzzer sounds 0.4 sec. each 0.8
th
sec. (0.4 / 0.4 sec.).
• LEDs "Fire" (L1) are blinking (0.4 / 0.4 sec.).
• Output for routing equipment (Fire Brigade TX) and outputs type “Routing
equipment” are activated. See also Note below.
• Programmable outputs for fire alarm are activated
39
• In the FT128 display, a presentation number (zone/address) with a user
definable text message (alarm text) is shown (if programmed).
Note: Normally the FDCIE relay output "R0" is used as the output for Routing equipment
(Fire Brigade TX). The output will then be activated for fire alarm from any alarm point or
Zone Line Input.
If the fire alarm routing equipment has provision for transmission of several fire alarm
signals and the alarm receiver has provision for reception of several fire alarm signals, the
alarm receiver can take different actions depending on if it is a fire alarm type A or B.
If a fire alarm type B is received, it will indicate that only one Analogue addressable
smoke, heat or multi detector is activated, which could be a nuisance alarm.
If a fire alarm type A is received, it is probably a real fire since fire alarm is then activated
from:
• Two or more Analogue addressable smoke, heat or multi detectors.
• Any Manual Call Point
• Any Zone Line Input
• Any programmable input with the trigger condition "General Fire"
For more information on alarm type A and B, see Technical / Programming manual.
Some Fire alarm examples:
One alarm point activating fire alarm (e.g. detector 12-45)
001 ZONE-ADDR 12-45 LAST ZONE 12 No. 01
"Alarm text for 12-45"
One zone activating fire alarm (e.g. zone 14; a conventional Zone Line Input)
001 ZONE 14 LAST ZONE 14 No. 01
"Alarm text for zone 14"
More than one alarm point activating fire alarm (e.g. detectors 12-45 & -46)
39
Programmable outputs for "General fire alarm" and for the activated fire alarm(s).
