The success of the original YardGuard providing positive inmate control in outdoor areas has led to many requests for a YardGuard system that can be utilized within indoor areas. In response to these requests we have developed the new RoomGuard system, specifically designed to use the successful YardGuard features in an inside room or exercise yard.

RoomGuard is a self-contained high pressure, low velocity water system capable of shooting short water pulses at targets up to 80 feet away. The short water pulses release a minimum amount of solution while being completely saturated with pepper spray. The water pulse, when contacting the target, saturates the target’s clothing and atomizes to saturate the air around the target. Each pulse uses approximately two gallons of water with pepper spray. This small amount of material is easy to clean up. The water pulse “bullet” is traveling at approximately 120 miles per hour and is safe to targets beyond a minimum distance of 10 feet.

RoomGuard is completely contained in an enclosure that can be wall, ceiling or post mounted. The complete system, less control panel, is contained in an enclosure 2 feet wide by 2 feet deep by 4 feet in height. The RoomGuard nozzle is a straight bore type specifically engineered to provide a pulse (bullet) of water with minimal side spray. A special valve on the end of the nozzle caps the nozzle when not in use and prevents dripping.
