OPERATION IN CASE OF FIRE
The fire suppression system can be activated in two
ways:
1. Automatically by heat, sparks and/or smoke detec-
tors.
2. Manually at the manual call point.
If there is a fire, the automatic sequence of events is as
follows:
• Acoustic fire alarm activation
• Fan motor is switched off
• Release of compressed air through solenoid valve
After a delay of 5 seconds:
• Sliding valves close
• Release of aerosol by Flame Guardian™ generator
After activation, the Flame Guardian™ remains active
for at least 30 minutes to prevent re-ignition of the fire.
This is to keep damage to the filter, as well as conse-
quential loss, to a minimum.
NOTE: Notify all parties involved that you will be test-
ing the fire safety system; See Maintenance
Section.
FUNCTIONAL TEST AND COMMISSION-
ING
To avoid accidental fire alarms and activation of the
Flame Guardian™ fire extinguishing generators,
always follow the following sequence for installation,
commissioning and maintenance.
1. Before starting, de-energize the Guardian™
Panel and/or electrically isolate the Flame
Guardian™ modules.
2. Make all connections to the Guardian™ Panel, with
the exception of the Flame Guardian™ modules.
3. Make all connections to the system control panel.
4. Create a temporary bridge to the terminal(s) for the
Flame Guardian™ with the End Of Line resistor-
diode to avoid fault alarm. See Wiring Diagram.
5. Apply the correct input power to the panel. When all
connections are correct, all indicator LEDs are off
and the display shows the text “System OK”. Make
sure panel is in RUN mode.
6. Test the detectors and system control panel as
instructed to make sure that the system is reacting
as expected and required. See specific Functional
Tests in Installation Section.
