If I were to install a new door-bell transformer and/or a new receptacle for security system, is it acceptable to install these devices above a drop ceiling in the basement and then cover them up ?

Transformers don't put off very much heat, but there still a danger ?

My initial thought would be no. Someone might have to trouble shoot your doorbell system someday. And the rules for the wiring would be different for the supply and load side of the transformer. I'm curious what Fretwell had to say.
