Toad Ai606

The Toad Ai606 has been around since 1999 and is a proven, reliable product. The Toad brand is now owned by Scorpion Auto.

Protection for this system is provided via interior Ultrasonic sensors which can be adjusted manually.  

Each device is supplied with two, four-button remotes providing a variety of functions. These include silent Arm and Disarm and interior sensor bypass sometimes called ‘Pet Mode’. The remote can also operate three auxiliary outputs (if fitted), one of which can be timed for example to operate a turbo timer module if required.

Understanding Chirps and Flashes

Most indicator flash sequences indicate correct operation of the system and the three colour LED uses Red and Green with Orange for error codes.

Interpreting LED Flahes and Status for Toad Alarms

No of Flashes Explanation
RED - Slow flash Car is armed
None Car is disarmed
GREEN - Quick flash Car is in the process of arming
GREEN - Solid Immobiliser arming
RED - Solid Immobiliser is armed


If on starting the ignition three orange indicator flashes take place, this shows that the alarm was triggered (set off). The LED will then flash a sequence between three and seven to say what triggered the alarm. This sequence is repeated twice more to give three cycles in total.
