13 Alarm types
In case of a fire, sensors, conventional smoke and/or heat detectors,
manual call points or programmable inputs can generate fire alarm.
When somebody break into a key cabinet, it will also generate a fire
alarm.
The sensors can generate three types of "fire alarm"; Pre-alarm, Fire
alarm and Heavy smoke alarm, see below.
The control unit can handle up to 130 pre-alarms and fire alarms. No
more "alarms" will be generated until one or more of the 130 alarms is
(are) reset.
13.1 Pre-alarm
Pre-alarm is a programmable option ( Win512 ) and will not be
activated if not programmed. A sensor generates pre-alarm for a
lower offset (level)
24
than the offset (level) for fire alarm.
Pre-alarm could be used when early alarm / actions are required but no
activation of alarm devices, routing equipment, etc. (e.g. computer
"soft" power off).
In case of a pre-alarm, the following will happen:
•
The buzzer in the control unit sounds 0.8 sec. each 4
th
sec.
(0.8/4sec.).
•
Output(s)
25
programmed for pre-alarm is(are) activated.
•
LEDs "Fire" (L1) are blinking.
•
On the first row in the control unit(s) display, the
presentation number is shown (for the first pre-alarm).
Example; pre-alarm zone 123 address 45:
•
If more than one pre-alarm are generated, the LEDs "Alarms
queued" (L2) are blinking and the pre-alarms will be
automatically scrolled (each five seconds).
Pre-alarm is automatically reset see chapter "Alarm reset", page 33.
24
Pre-alarm offset < fire alarm offset and is programmable in Win512 and is
valid for the whole system. Regarding the BS4 exp. board 1584 for
Autronica devices (BS4 loops), pre-alarm can also be generated by
detector(s) connected to address units.

And output(s) programmed for this specific pre-alarm.
