Alarm types
In case of a fire, analog detectors (sensors), conventional smoke
and/or heat detectors, manual call points and programmable inputs can
generate
fire alarm
.
42
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 two other types of "alarm", i.e.
Pre-warning
and
Heavy smoke alarm
/
Heavy heat alarm
.
"Two unit dependent" addressable alarm points (normally only smoke
detectors) and "2-zone dependent" zones, can generate a
Co-incidence
alarm
.
Quiet alarm
is normally used for fan control only.
EBL512 can present up to 512 fire alarms (alarm points and/or zones).
Zone numbers 001-999 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 EBL512 display (LCD) 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.
15.1
Pre-warning
Activation of Pre-warning is an option that has to be enabled (via
Win512) for the c.i.e. respectively.
Note!
Pre-warnings activated in
any control unit in the system will be presented in all control units and
all programmable outputs in the system (with trigger condition pre-
warning) will be activated (if not disabled).
An analog detector will generate a pre-warning for a lower alarm level
than the fire alarm level.
43
Pre-warning can be used when an early
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:
42
In the New Zealand convention only, a Fire alarm (ALM) can be
"changed" to an Acknowledged alarm (ACK) or an Isolated alarm (ISO).
43
See EBL512 Planning Instructions. Any programmable input can also be
used to activate a pre-warning.
Regarding the BS4 exp. board 1584 for Autronica devices (BS4 loops), pre-
warning can also be generated by detector(s) connected to address units.
