FREQUENTLY ASKED QUESTIONS & MISCONCEPTIONS
- When one fire sprinkler head goes off, they all
go off.
- This is only true in a deluge
type system. The majority of sprinkler systems utilize sprinkler
heads that react to temperature. This means that the only heads that
activate during fire are the heads that are in the immediate area of a
fire.
- Aren't fire sprinkler systems expensive?
-
Fire sprinklers are one the least expensive of all the construction trades and
usually costs between $1.00 to $3.00 per square foot depending upon the type
of building construction and use. The cost of installing a fire
sprinkler system usually results in a savings on your insurance premiums.
- Why do I have to put sprinklers in my building?
-
In the state of Ohio, sprinklers are required by the Ohio Building Code for
most buildings. Sprinkler systems may also be required by your insurance
company. The type of sprinkler system that is to be installed depends
upon construction type and use of the building.
- What type of sprinkler system do I need
installed?
- The Ohio Building Code
requires that sprinkler systems be designed and installed in accordance with
National Fire Protection Association standards. Your insurance company may
require more stringent standards be followed. It is best to involve your
insurance company at the beginning of any construction project.
COMMENTS
Wet Systems vs. Dry Systems.
-
Wet systems require temperatures above 40 degrees to stay
operational.
-
Wet systems react quicker and require
less maintenance than dry.
-
Dry system piping tends to corrode
more quickly than wet system piping.
-
Dry systems are more expensive to
maintain but can be installed in cold areas.
-
Dry systems require a greater number
of sprinklers be hydraulically calculated which results in a greater pressure
and water demand.
CPVC (plastic sprinkler piping)
-
CPVC piping does not rust or corrode.
-
CPVC piping and is not subject to
MIC's (micro-biological corrosion).
-
CPVC piping can only be used on wet
sprinkler systems in light hazard areas.
-
CPVC piping has better flow
characteristics than steel piping and subsequently results in smaller pipe
sizes.
