OC Intruder-Buster™ Tripline Pepper Spray System
The O.C. Intruder-Buster™ (OIB) is a tripline-activated area denial device powered by a DPS O.C. fogger. When an intruder trips the line, the unit releases a cloud of O.C. pepper spray, giving them a strong reason to leave the area fast. DPS developed the OIB in collaboration with Shomer-Tec.
Where It Works Best
The OIB is best deployed outdoors or in outbuildings, especially where travel naturally funnels through a narrow path, such as between buildings, along hedges, or at a gate. The design is simple, and it is extremely effective at protecting an area.
The OIB runs on a proprietary DPS O.C. fogger canister made specifically for this device. Made in USA.
What's in the Kit
- Housing
- Activator assembly
- Safety pin
- Wall mount
- Sear
- 75 ft of trip line
- 2 mounting screws
- One 4 oz DPS pepper refill unit
Refill and Inert Training Units



Refill units are live 4 oz DPS O.C. fogger canisters that put the OIB back in service after it is triggered. Inert training units contain no O.C., so you can practice setting up, arming and triggering the system safely.
How to Set It Up
- Before anything else, push the safety pin through the housing so the open end comes out through the holes on the opposite side.
- Remove the cap from the DPS refill unit and insert it nozzle first into the housing.
- Attach the trip line to the sear. Compress the activator assembly with one hand and set the sear into position on the plunger.
- Screw the activator assembly onto the housing, leaving just enough gap to slide the unit onto the mounting bracket, then tighten so the housing is firm on the bracket. The spray exit hole should face up.
- Carefully set your trip line. Once everything is inspected, remove the safety pin. The unit is now live.
- When approaching a live unit that has not been triggered, always insert the safety pin before taking it apart.
