A New Approach to Retrofitting.
Fire protection safeguards lives and property
against the most common hazard there is. No
building should be without a Carlysle fire
protection system. Carlysle not only installs
sprinkler systems in new buildings as they are
erected, but we also retrofit existing
structures. This takes special skill, creativity
and experience-attributes that have set Carlysle
apart for more than five decades. For example,
pipe routing is carefully planned so that the
aesthetics of the building are preserved.
Installation work is scheduled to minimize
interruption to the workflow of your employees.
We plan jobs to ensure your warehouse is not
disrupted. In short, Carlysle’s sensitivity to
the needs of our clients has earned us a
reputation as the first choice in fire
protection throughout New England.
Commitment to Customer Service.
Carlysle operates its own pipe application plant
in Boston. The company is one of the few firms
that do, but we believe this gives us greater
control over quality and allows us to be more
flexible when it comes to meeting our clients’
needs. We have a stock of pipe, fittings,
hangers, sprinklers, valves and special
equipment that is virtually unmatched. And
Carlysle backs up this “behind-the-scenes”
difference with a commitment to customer service
that is unsurpassed. In fact, we are available
to our clients 24 hours a day, 365 days a year
with insurance-approved inspection programs.
Water, an Elemental Advantage.
Carlysle knows from long experience, and the
National Fire Protection Association agrees,
that sprinklers are the most effective means of
controlling fires in buildings. Not only do they
sound an alarm, they react immediately with the
most efficient fire-fighting agent there is -
water. Furthermore, sprinklers concentrate
directly on the fire and operate until the fire
is completely extinguished.
The bottom line is that the National Fire
Protection Association states that automatic
sprinkler systems are 92.6% effective. Carlysle
company records show that six times out of ten,
sprinklers extinguish fire without the need for
From a simple two- head sprinkler renovation in
the Children’s Museum to large projects such as
the 40-Story Exchange Place and the World Trade
Center, Carlysle has the experience and
resources to get the job done on time, on
budget, and on par with your highest
expectations. Whether your project is small or
large, you can count on Carlysle Engineering
Inc, the Fire Protection People.
The Latest Hydraulic Technologies.
Carlysle has installed a wide variety of fire
suppression systems which include:
A Wet Pipe System in which the piping is
normally filled with water under
A Dry Pipe System in which the piping is
normally filled with air under pressure but
into which water is automatically admitted
when a sprinkler head opens.
A Deluge system which is empty and open at
the heads, and in which a separate network
of heat detectors, either pneumatic or
electric, allows water to enter the
distributive pipe work and flow through all
the open heads upon operation. Special
high-hazard nozzles are sometimes used in
the systems in place of sprinkler heads.
A Pre-Action System consisting of a sealed
sprinkler system in which a separate network
of heat, pneumatic and/or electric detectors
allows water to enter the distributed
system, creating a wet pipe system.
Combined Dry Pipe and Pre-Action System in
which the features of both dry pipe and
pre-action systems are combined. This system
is often used to protect extremely cold
areas such as a blast freezer, with the heat
responsive system also serving as an
automatic fire alarm system.
Special Purpose Systems which depart from
the requirements of NFPA Pamphlet #13, such
as special water supplies, reduced pipe
sizing, large drop sprinkler systems, and
Special Hazard Systems include low and
high expansion foam, FM 200, Inergen, low
and high-pressure CO2, dry chemical foam,
foam turret and water cannon systems.
From Steel to Plastic Pipe.
It used to be that steel pipe and cast iron
fittings were the industry standard. Today,
Carlysle offers a variety of options, including
stainless steel, copper and plastic piping. Each
of these materials in turn requires special
hanging considerations, fittings and
installation techniques. Carlysle’s experience
is virtually unmatched in the region, and our
expertise has gained us recognition in a variety
of publications. But the greatest achievement
comes in Carlysle’s ability to exceed the
expectations of its clients. For example,
Harvard chose Carlysle Engineering Inc. to
handle the copper sprinkler installation at its
School of Public Health, and then selected us to
install a stainless steel pressfit system in its
massive Widener Library building. Carlysle has
also led the industry in the use of innovative
materials such as plastic (CPVC) pipe, handling
retrofits of existing high-rise buildings for
the housing authorities of Quincy, Somerville,
Brockton, Cambridge and Southbridge. When it
comes to product knowledge and innovation,
Carlysle sets the standard.
