ABSTRACT:
A frame for supporting a sheet of glass over a fire alarm signal switch mounted on a wall. The frame is of the type which holds the glass over the switch so that the alarm signal can only be operated by breaking the glass. The frame has a cover member with an open bottom so that when the glass is broken to operate the alarm the resulting shards of glass fall through the open bottom of the cover member so that they do not injure the operator.
