However, iluminação de emergencia balizamento if the sprinklers exhibit resonance at a frequency within this range, the resonant frequency shall be used all through the test interval. Computerized sprinklers shall withstand the results of vibration with out deterioration of its efficiency characteristics. Sprinkler samples shall be installed in a water crammed test line connecting with a small motor operated piston pump that produces a rapid rise in discharge strain from three.5 to 35 bars at the fee of 60 cycles/min. For an upright sprinkler, the deflector of the sprinkler shall be a hundred mm below the ceiling and for a pendent sprinkler a hundred and fifty mm under the ceiling (see Fig. 7 and 8).

Ceiling/storage Height
Clauses 10(a) and (c) require that sprinkler valves positioned in an area usually used by the stage manager (for theatres, halls or over a stage area), to be fitted with anti-tamper devices related to a monitoring panel. Stages used for live performances can contain excessive hearth hundreds because of the scenery and other props used in these productions, and particularly hazardous stage actions, corresponding to pyrotechnics. To present for the continued operational effectiveness of sprinkler heads in sure areas.

The strain of 30 bar shall then be maintained for a period of 3 min + 5 s and then allowed to fall to zero bar in not lower than 5 s. The stress shall be raised from 0 bar to 30 bar at an average rate of ≤ 1 bar/s. The nominal temperature for fusible parts shall be completely colored as indicated in Table 3 with a variability in working temperatures throughout the ranges specified. The nominal temperature for glass bulbs shall be permanently coloured as indicated in Desk 2 with a variability in operating temperatures throughout the ranges specified. A fusible element sprinkler is opened under the affect of heat by melting of a part. Sprinklers of the next varieties are coated underneath this standard. The part of a sprinkler that retains the heat responsive element in load bearing contact with the sprinkler head va
