1. PRE-ACTION SYSTEM DESIGNED AS A DOUBLE INTERLOCK ELECTRIC/ELEC-PNUEMATIC:
(2) OPERATIONS NEED TO HAPPEN BEFORE THE SOLENOID VALVE ACTIVATES THE
DELUGE VALVE AND ACTIVATES THE FIRE SPRINKLER SYSTEM:
a - SMOKE DETECTOR IS ACTIVATED.
b - LOW PRESSURE SWITCH IS ACTIVATED DUE TO THE LOSS OF AIR IN THE SPRINKLER
SYSTEM BECAUSE OF SPRINKLER ACTIVATION.
SD
2. IF SMOKE DETECTOR IS ACTIVATED A SUPERVISORY ALARM IS SENT TO THE FACP AND
THE LOCAL ALARM (ELECTRIC BELL) IS ACTIVATED.
STORAGE AREA
3. IF LOW PRESSURE SWITCH IS ACTIVATED A SUPERVISORY ALARM IS SENT TO THE FACP
AND LOCAL ALARM (ELECTRIC BELL) IS ACTIVATED.
4. IF A CONTROL VALVE IS MOVED FROM ITS OPEN POSITION A SUPERVISORY ALARM IS
IS SENT TO THE FACP AND LOCAL ALARM (ELECTRIC BELL) IS ACTIVATED.
5. IN THE CONDITION THAT A SMOKE DETECTOR AND THE LOSS OF AIR PRESSURE BELOW
20 PSI IS MET THE SOLENOID VALVE IS TRIPPED AND THE DELUGE VALVE IS OPEN, ALARM
PRESSURE SWITCH SENDS A SIGNAL TO FACP THAT PRE-ACTION SYSTEM IS IN A FLOWING
CONDITION INITIATING BUILDING FIRE ALARM SYSTEM.
