What reading level is Automatic Sprinkler Protection book?
To quickly assess the difficulty of the text, read a short excerpt:
A few of the more important points that are often overlooked are the following: 1. Vent for circuit closer. There should be a small outlet about J inch in diameter located under each cir- cuit closer so that when the water flow ceases the pres- sure under the diaphragm will be released at once and the circuit will be thereby broken. This also allows the pipe from the diaphragm to drain quickly by admit- ting air at the upper end. The vent should be piped through a visible outlet and so arranged... that water discharged from it will do no damage.
2. All drips should run to the space under the build- ing or out of doors in such a manner that the chance of clogging or freezing will be reduced to a minimum. Drips running to a sewer are liable to cause trouble by the backing up of water which may operate the alarms. When it is necessary to connect to a sewer, the drip pipe should run into an open cup or into a pipe of larger diameter, this latter pipe running to the sewer. The top of the cup can be closed with a sliding cover if desired and this, not being air-tight, will prevent any back pressure from reaching the retarding chamber.
