SPARK DETECTORS

DIMENSIONING OF SPARK DETECTOR SYSTEM

 

The elements to be considered for dimensioning the system are the following:
• Ducting: diameter, length and air speed.
• Safety level required: with or without monitoring station.
• Water: pressure.
The duct diameter determines the choice between single detector and pair. Up to 500mm diameter, the duct is considered small and a single detector is sufficient (small systems type “A” and “E1”). Over 500mm diameter the duct is considered large and a pair of detectors is required (large systems type “B” and “E”).
The safety level required determines the choice between systems that perform only detection and extinguishing operations (simple systems type “A” and “B”) and those that also provide monitoring (complete systems type “E1” and “E”).

SYS-A

Small simple system* It includes:

no. 1 RIV-601P/S spark detector

no. 1 SAM-871 mounting frame

no. 1 PAN-705 control panel

no. 1 SNA-808L alarm sounder beacon

no. 1 EVS-811 solenoid valve

no. 1 UGN-820 spray nozzle

SYS-B

Large simple system* It includes:

no. 2 RIV-601P/S spark detector

no. 2 SAM-871 mounting frame

no. 1 PAN-705 control panel

no. 1 SNA-808L alarm sounder beacon

no. 1 EVS-811 solenoid valve

no. 2 UGN-820 spray nozzle

SYS-E1

Small complete system* It includes:

no. 2 RIV-601P/S spark detector

no. 2 SAM-871 mounting frame

no. 1 PAN-705 control panel

no. 1 SNA-808L alarm sounder beacon

no. 1 EVS-811 solenoid valve

no. 1 PAC-846 water flow switch

no. 1 UGN-820 spray noozle

SYS-E

Large complete system* It includes:

no. 4 RIV-601P/S spark detector

no. 4 SAM-871 mounting frame

no. 1 PAN-705 control panel

no. 1 SNA-808L alarm sounder beacon

no. 1 EVS-811 solenoid valve

no. 1 PAC-846 water flow switch

no. 2 UGN-820 spray nozzle

Note:

  • “A” and “B” systems are “simple” bacause they only perform the detection and extinguishing operations, but not the monitoring functions.
  • “E12 and “E” systems are “complete” because they include all functions of detection, extinguishing and monitoring.
  • “Small” systems are suited for ducts with diameter up to half meter
  • “Large” systems are suited for ducts with diameter up to one meter.
