Directed Acquires Alcohol Detection Systems

Breathlyzer-based ignition devices require drivers to pass before vehicle starts

Directed has acquired Alcohol Detection Systems (ADS), a provider of breathalyzer-based ignition interlock devices (IIDs) under the Determinator line.

Drivers with IIDs installed in their cars must successfully pass a breathalyzer test before the car will start. According to Directed, evidence shows that IIDs have a positive effect on reducing the incidence of drunk driving.

The company plans to maintain the Determinator line going forward.

“Ignition interlock devices really do save lives, and the growth of the IID market has been driven by the major benefit they provide to society,” said Directed CEO Bob Struble in a statement. “Directed and ADS share core technology, and we are confident that by bringing our leading product design, technical service, and distribution capabilities to the IID market, we will rapidly expand ADS’s business. IIDs are primarily installed by mobile electronics retailers and auto service shops, and we are excited to bring this new business opportunity to our longstanding partners.”

Directed is a division of DEI Holdings, a portfolio company of private equity firm Charlesbank Capital Partners, whose brand family includes Polk Audio and Definitive Technology. Charlesbank acquired DEI Holdings in 2011.
