Alarm types

In case of a fire, analog detectors (sensors), conventional smoke
and/or heat detectors, manual call points and programmable inputs can
32
generate fire alarm. If somebody illegally breaks into a key cabinet,
this will also generate a "fire alarm" (a Key cabinet alarm).
A fire alarm could be an Alert Annunciation alarm, i.e. the
activation of the routing equipment (fire brigade tx) is delayed during
an acknowledgement time and an investigation time respectively.
In the Australian convention only, an Alarm Acknowledgement
Facility function can be used. During the Acknowledgement Period
and the Investigation Period respectively, there will be an indication in
the c.i.e. display.
The analog detectors can also generate other type of "alarms", i.e.
Pre-warning, Heavy smoke alarm / Heavy heat alarm and a two-
unit / -zone dependent alarm point / zone can generate a Co-incidence
34
alarm. Quiet alarm is used for fan control.
EBL128 can handle and present up to 256 fire alarms (alarm points
and/or zones). Zone numbers 01-99 can be used and in each zone the
alarm point (address) numbers 01-99 can be used. The fire alarms
will be shown in the EBL128 display and in Ext. FBP 1826 / 1828,
Alert Annunciation unit 1735 / 1736 and Ext. Presentation unit 1728.
Regarding the different alarm types, etc., see the following chapters.

Pre-warning

An analog detector will generate a pre-warning for a lower alarm level
than the fire alarm level.
alarm and/or an early action is required (e.g. a "soft" computer shut
down). Normal alarm devices, routing equipment, etc. will not be
activated.
In case of a pre-warning, the following will happen:
 The buzzer in EBL128 sounds 0.8 sec. each 5
sec.).
 Outputs programmed for pre-warning are activated.
 On the first row in the EBL128 display, the presentation
number (zone-address) is shown (for the first pre-warning).
32
In the New Zealand convention only, a Fire alarm (ALM) can be
"changed" to an Acknowledged alarm (ACK) or an Isolated alarm (ISO).
33
This is done via a programmable input.
34
This function is normally used for smoke detectors only.
35
See EBL128 Planning Instructions. Any programmable input can also be
used to activate a pre-warning.
36
Outputs programmed for General pre-warning and outputs programmed
for the activated pre-warning(s).
