March 1, 2001 Foam 20a 1. DESCRIPTION A De luge Blad der Tank Foam/Wa ter Sys tem is a stan dard de luge sys tem ca - pa ble of dis charg ing a foam/wa ter so lu - tion au to mat i cally through open sprin - klers, spray noz zles, mon i tor noz zles, and other dis charge de vices. A De luge Blad der Tank Foam/Wa ter Sys tem with a hy drau li cally ac tu ated Halar coated Vi king De luge Con cen trate Con trol Valve ( CCV ) con sists of a stan dard de - luge sys tem us ing a Vi king De luge Valve com plete with full stan dard trim and de tec tion and re leas ing de vices on the wa ter supply line, a con cen trate con trol ler-proportioning de vice with ap - pro pri ately sized or i fice, a hy drau li cally ac tu ated Halar coated Vi king De luge CCV on foam con cen trate line, a foam con cen trate blad der tank and trim and foam agent. 2. OPERATION Ac tu a tion of the re lease line (pneu- matic, hy drau lic or elec tric) re lieves the pres sure in the prim ing cham ber of both the Vi king de luge valve (C) and the Halar coated Vi king de luge CCV (D). This al lows the clap per to open on both valves (C) and (D). The sys tem pip ing is filled with wa ter, ac ti vat ing con nected alarms and pres sur iz ing the blad der tank (A) by the wa ter sup ply pip ing (12). Sys tem wa ter pres sure in the space be - tween the flex i ble blad der and the in side sur face of the steel tank, causes the blad der to col lapse, forc ing the foam con cen trate out through the foam con - cen trate dis charge pip ing (15), Halar coated CCV (D), and the me ter ing or i - fice of the con cen trate con trol ler (B), into the venturi, (low pres sure) area of the con cen trate con trol ler (B). The foam con cen trate is pro por tioned (usu- ally 1%, 3% or 6%), with the main wa ter sup ply, send ing foam so lu tion to the sprin klers and foam/wa ter dis charge de vices down stream. 3. DISCHARGE DEVICES Open stan dard spray sprinklers Foam/wa ter sprin klers Non-aspirating spray noz zles Man ual and os cil lat ing mon i tors Foam cham bers Sub-surface in jec tion (forcing foam maker) Hose reels and hand lines... and other dis pens ing de vices 4.

Set release and detection sys - tem according to installation in - structions for type of release used (Pneumatic, Hydraulic or Elec tric) 4. Prime both Vi king De luge valves (C & D) by open ing the prim ing valve on the de luge valve (C) trim. Bleed off any air pres sure trapped in the prim ing line (13) to the Halar coated CCV (D) by open ing the 3 way pres sure gauge valve (14). Once air pres sure has been re lieved, close the 3 way valve and plug out let. Re-open 3 way valve to main - tain pres sure on gauge (14) 5. When pres sure in de luge valve (C) prim ing cham ber equals sys tem wa ter supply pres sure, turn on sys tem wa - ter sup ply by open ing main drain on de luge valve (C) and partially open ing wa ter sup ply valve (10).

Make sure the fire is OUT! Make a com plete in spec tion of all ar eas cov ered by this sys tem in clud ing ar eas not in - volved in the fire. Place a fire watch in the en tire area un til the sys tem is back in ser vice. 2. Close the sys tem wa ter supply con trol valve (10). Post a per - son at the valve ready to turn it back on, should the fire re kin - dle. Close the tank wa ter sup - ply valve (11). 3. Open the flow test an gle vlave, sys tem drain valve and all auxillary drain valves. Close drain valves once the sys tem has com pletely drained. 4. Re place any fused sprin klers in the pilot line (if so equipped), with the same type and tem - per a ture rat ing as were re - moved. Check all re leases and/or de tec tors in the fire area for dam age. 5. Iso late the blad der tank (A) by clos ing the con cen trate con - trol shut-off valve (9***) and ver ify that the tank wa ter sup - ply con trol valve (11) is closed. 6. Check the level of foam con - cen trate and re fill the foam con cen trate blad der tank (A) by fol low ing tank man u fac - turer s in struc tions. Al ways re place the foam con cen trate with the same brand and type as that be ing used cur rently. Note: Never in ter mix dif fer ent types or brands of foam con - cen trate, as this could cause them to gel or so lid ify, and ren der the con cen trate use - less. 7. Re turn the com plete sys tem to ser vice by fol low ing the pro - ce dure listed in Sec tion 6C, Steps 6 through 14. 8. Per form quar terly test. 9.
