This is the Directed DS4SU security upgrade kit.

If you already have a compatible Directed remote starter fitted, this adds the alarm functions to it. You keep the system and the install work you've already paid for.

What's in the kit

• Six-tone mini siren — cycling tones are far harder to tune out than one continuous note
• 8504D digital (D2D) sensor — shock, tilt and temperature in one module

Temperature sensing is the unusual inclusion. Alongside security it feeds cold-weather start logic, so the vehicle can start itself when it needs to rather than on a fixed timer.

Requires a compatible Directed control module. Not sure what's in your vehicle? Call us on 647-439-4485.
