Small in size, big on security

The 446RLi is the small alarm that's big on protecting your vehicle. With an alarm module far smaller than others in the market, hiding the unit during installation is much easier, making it less accessible to thieves. The 446RLi also has an attack proof security housing that safely protects the immobiliser connections.

Digital battery back up siren 

The unique sounding Digital battery back up siren is a true digital siren with no override key. The siren features soft arm/disarm chirps or can be set to silent arm mode.

Custom programming

The 446RLi supports double lock pulse deadlocking on selected vehicles. The alarm can also be programmed to operate selective unlocking, boot pop, full window closure and internal light switch-on upon disarming and ignition turn-off.

Glass break sensor

Built-in amplifiers filter and amplify the noises inside the cabin of vehicle. When the high frequencies associated with breaking glass are detected, a trigger signal is sent to the alarm system.
