I have just started doing such with in the last year, however i have not received any complaints as of yet about any problems. To answer your questions, no i just used the same as i was using inside the home. However i just spent about an hour researching your question and have found that it is NOT recommended to install in such locations. The apps i installed had a attic fan and gabble vents so it never surpassed 100 degrees up there but im sure it got chilly up there. I see BRK makes a heat dectector that trips around 130 or if a increase of more then 15 degrees with in a minute. Maybe these could be used. I myself will discontinue putting them in said locations untill i speak with a company rep. On the same kind of topic i feel it should become code to require strobe/horn in res. applications. I recently saw a talk show about how people sleep through regular detectors it was scary. Esp as a firefighter.{ Alittle long winded sorry}
