Technical specification Options coding
The air horns are operated from a 0.5 to 1.5 bar pressure supply with air consumption of typically 15 to 30 Nl/min. Higher pressures can also be used if the supply is restricted. For operation with a 1.5 to 4 bar supply a 2mm-diameter restriction should be fitted, for operation with a 4 to 10 bar supply a 1mm-diameter restriction should be fitted. Multiple horns may be used from a single supply to give a wider sound spread. Two horns used in this way will increase the sound output to 121dB(A) at 1 metre. A restrictor should be fitted in the supply of each horn to ensure that in the event of one horn being damaged the supply pressure to the others will not be affected. Pneumatic connections are available
for 6mm or 1/4" metal, nylon or plastic tubing. In addition
connections are available for PVC covered copper tube. |
