You would never use beam detectors in a garage and especially in an open structure like this. Consider the fact that cars emit smoke and other exhaust gases, the detectors would be alarming all the time.
AS in the area is all you should need. The area is heated right? Also in some jurisdictions, (rain) water run off from cars is routed to oil separators before being discharged into the sanitary or storm sewers. Make sure someone has verified that the drains could handle the discharge from the calculated sprinkler flow. Otherwise you could end up with an underground pool and lots of flooded cars. Even though this is more of a plumbing issue. It's a good idea to send an e-mail notifying someone of the potential problem. Craig L.
