- FIRE ALARM SOLUTIONS OPERATING INSTRUCTIONS
36
Pre-warnings activated in any control unit in the system will always be presented in all control units and all
programmable outputs in the system (with trigger condition pre-warning) will be activated (if not disabled).
18. ALARM
In case of a fire, analog detectors (sensors), conventional smoke and/or heat detectors, manual call points and programmable
inputs can activate fire alarm. If somebody illegally breaks into a key cabinet,
this will also activate a "fire alarm" (i.e. a key cabinet alarm).
18.1. ALARM TYPES
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. The analog detectors can also activate 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 activate a
Co-incidence alarm
.
Quiet alarm
can be used to activate outputs, based on smoke detected by a smoke detector, without activating a fire alarm in the
system.
If the
Local Alarm Acknowledgement
function is used there will be an indication in the c.i.e. display during the Acknowledgement
Period and the Investigation Period respectively.
Regarding the different alarm types, etc., see the following chapters.
In the following chapters are all different alarm types described. The illustrations in this document show the essential information
and might not look exactly as shown in the display.
18.1.1. PRE-WARNING
Activation of Pre-warning is an option that has to be enabled (via EBLWin) for the control unit respectively.
An analog detector will generate a pre-warning for a lower alarm level than the fire alarm level. Pre-warning can be used when
an early warning and/or an early action is required (for example a "soft" computer shut down). Normal alarm devices (output type
"Alarm devices"), routing equipment, and so on will not be activated.
Any programmable input can also be used to activate a pre-warning, e.g. for a High Sensitivity Smoke Detector system. Aspirating
smoke detector Aspect Lazeer (AE2010L-P) programmed for Detection type "And with pre-warning" will activate a pre-warning for
"alarm" from one detection area only.
See EBL512 G3 Planning instructions for the system.
