The Autowatch 160RLi security system incorporates several sensing systems to protect your vehicle. Each time the system is turned on, these sensing systems start to monitor the vehicle and if unauthorised interference is dected, the alarm system will be triggered. The system also features dual-circuit immobilisation to frustrate attempts to start the engine by hot-wiring. Even if the battery is disconnected or the power supply wires are cut, the self-powered siren will continue to sound.
