​​RP-85 EBW Detonator ​

P/N 188-7080​

The RP-85 detonator has the same output as the RP-83, however it is sealed for under-water use. All RP-85 detonators are individually tested to 1000 psi water pressure.



RP-85 Firing Parameters
Threshold Burst Current:180 amps
Threshold Voltage:Approx. 500 volts
Threshold Voltage Std. Deviation:75 volts maximum
Function Time:5.38 µsec. typical
Function Time Simultaneity
Standard Deviation:
0.125 µsec Max.

Caution:While EBW and EFI Initiators are inherently less susceptible to accidental detonation during handling and set-up than devices containing primary explosives, electrical and electronic firing systems are sensitive to transient electrical energies which could cause premature triggering or firing. The blasting area must be clear of personnel and equipment before the detonator leads are connected to any RISI Firing System. Only approved RISI Firing Systems should ever be used to initiate or detonate any explosive product manufactured and authorized for sale by RISI.
