Exactly the same as the PBU-8 with one exception, there is a built in Wilson F/X wireless unit.
This is an 8-pad pad-box with a built-in wireless unit along with 8x 30-foot-long igniter leads and comes with a 12-gallon hinged lid storage container for the PBU and its igniter leads. This is like the large muscle of the WFX system. Reads good/bad continuity at the pad, as well as voltage of the battery at the pads with built in piezo buzzer. Continuity check is safe for ALL known commercial igniters including flashbulbs. When the bank of pads is armed a warning light is lit on the top of the pad-box and the piezo buzzer also screams its warning to everyone nearby. This unit has an auxiliary communications plug that the user can plug in a non-wireless WFX pad-box in order to piggy back off of its wireless unit. It is built into a standard 8x8x4 NEMA enclosure.
