Sprinkler System for the Home

Issue 9 and Volume 85.

Sprinkler System for the Home A modified form of the customary industrial sprinkler system for fire protection, is being installed by the Grinnell Company for home use. It is termed the “junior” system. The home system uses copper tubing, bent to go around beams and so forth. A loop of copper tubing carries water to sprinkler heads spaced twelve feet apart. The heads are of the new quartz type which open at 135°, thirty degrees lower than the old solder type. In case of fire, a sprinkler head opens, water pours through the loop, and a flapper valve is actuated so that an electric warning bell rings.
