FIRE ACTION PROCEDURE
In case of fire
When a fire is detected, the system can be activated
manually through a manual call point (See Manual
Call Point).
AUTOMATIC DETECTION OF FIRE
In the event of a fire, the system reacts as follows.
1. The display shows ALARM and indicates fire zone.
2. A Red alarm LED in specific zone flashes.
Audible/visible indicators are switched on and the
fire alarm sounder is activated.
3. The system control panel stops the fan, closes the
sliding valves and releases the compressed air
through the solenoid valve.
4. Five seconds after fire alarm, the Flame
Guardian™(s) is/are activated; LEDs OUTPUT 1
TO 4 will be lit.
NOTE: The Flame Guardian™ extinguishing material
is extremely fine. In case of fire, it may seem
like smoke escapes through the seams of the
filter system, but most commonly it is the extin-
guishing material which is harmless to environ-
ment and people.
