Panel Alarm Conditions
Fire Alarm Condition
Depending on the panel type (single or double Flood Zone) and the Gas Cards installed, the panel can
have one or two Flood Zones. Each Flood Zone can have 1
–
3 Detection Zones. The panel will enter
a fire alarm condition if:
•
One or more detectors in one or more Detection Zone are triggered
•
A call point is manually triggered
The display shows the location/origin of the fire alarm, and the total number of Detection Zones in a
fire alarm condition.
If two or more Detection Zones enter the fire alarm condition, the display shows the location of the last
zone to enter a fire alarm condition.
When in the alarm condition:
•
The
General Fire
LED and the respective Detection Zone
’s
Fire Zone
LED will be illuminated.
•
The general fire alarm bells/sounders (SOUNDER 1/SOUNDER 2) will activate (depending on
how they are programmed to respond).
To silence the internal buzzer, press the
Mute Buzzer
button.
To silence the bells, press the
Silence Alarm
button.
To reset the panel, press the
Reset System
button.
The status of the extinguishant release is also indicated. If a fire alarm occurs in a Detection Zone that
has no effect on the extinguishant control, then the display shows
UNAFFECTED
.
Activated/Released Condition
The extinguishant Activated/Released condition is established for a Flood Zone, when:
•
Two or more detectors in a single Detection Zone, or one or more detectors within two or more
Detection Zones, are triggered
•
When a manual
EXTINGUISHANT RELEASE
button, in the Flood Zone that is in an alarm
state, is pressed.
The Detection Zones that must be in a fire alarm condition, before the activated condition is invoked,
depends on the programming of the panel during installation.
Note:
In accordance with EN 12094-1, the activated/released condition may be established without the
detection of a fire alarm or manual release. If the panel detects the release of extinguishant, it will
immediately indicate the released condition.

•
The
Release Imminent
LED is illuminated on steady.
•
The display indicates
RELEASE IMMINENT
and shows a countdown timer with the number of
seconds remaining before the extinguishant is released.
•
Timer starts counting downwards to ‘0’
•
The release imminent sounder (1st Stage Sounder) will be activated within the Flood Zone in
the Activated/Released condition, to warn that extinguishant release is imminent.
