The ACS is only for use in operations such as drugs raids, where the officer may encounter a dangerous animal. The operator points the ACS at the animal and presses the red button activating the conductive strips. If the dog touches the strips it will receive a severe non-lethal shock. The strips also generate discharge sparks accompanied by loud crackling noises which will deter most animals

The shield has a 3mm thick clear LEXAN POLYCARBONATE front blade, a 3mmthick back pane, and a3mmfront panel as a mounting for the conductive matrix, in the same material. It has lightweight aluminium single loop handles with non-slip rubber grips for comfortable carry and secure hand grip. Mounted on the rear of the back panel is a control / electronics box which delivers a high voltage, low current power output via 2 wires to the conductive matrix on the front panel. A red button activates the device. A unique safety key attached by a lanyard to the operator ensures the device only operates when used by authorised personnel and de-activates the control box automatically if the shield is dropped or snatched by a hostile party.

Developed for UK police units only as a humane method of controlling dogs or other dangerous animals.
