Can I use a standard Diablo Controls detector for directional logic?

Diablo Controls has a specific model for directional logic applications, known as the DSP-21.

The DSP-21 Series is intended to be an ‘all-in-one’ vehicle detector designed for the parking industry. It was developed for systems that need accurate vehicle count information. This detector is designed to operate utilizing a dual inductive loop configuration typical in the parking industry.

This detector was designed to retrofit into existing locations that may require a detector upgrade. Sophisticated algorithms offer plug-and-play operation when using one of the counting modes. This detector offers a model that provides a contact closure for a loop failure condition. When wired to a system input, this allows the user to receive real-time status of the overall detection system.
