Mr. Boughton,
In response to your transmittal request received by this office on January 13, lg87,
I offer this response.
I cannot support a variance of deletion of fire sprinklers for the gymnasium of the
proposed Coppell High School. I can find no evidence to support water damage due
to a malfunction of a sprinkler head. Factory Mutual, a testing agency for insurance
companies, reports that only one (1) in sixteen million (16,000,000) sprinkler heads have
ever malfunctioned.
The National Fire Protection Association also states: "Partial systems are generally
not cost effective. Should the fire start remote to the system, sprinklers will have
no effect on the growing fire. A fire burning into the protected area, will generally
have developed sufficient intensity to overpower the sprinklers, thereby wasting water
needed by the fire service."
Your concern for vandalism in their the gym is pertinent to this department. Recent
vandalism in Garland and Carrollton resulted in some $1.5 million in losses to each school
district. A sprinkler system could have reduced the fire, smoke and water damage to
less than $1,000 each.
An alternative system to which you might consider is that of a "preaction system".
This is a dry sprinkler system that employs supplementary fire detecting devices within
the protected area. When activated, a valve operates, filling the piping system with
water. Water is not discharged until a sprinkler head is then "fused" from the heat
of the fire.
Thank you for the co-operation in the planning for fire safety for this facility.

REQUEST FOR DELETION OF FIRE SPRINKLER
SYSTEM FROM GYMNASIUM
ATTACHMENT
It is anticipated that the future City fire code for the City of Coppell
will require a fire sprinkler system for all buildings built within the
city limits, similar in type to the new Coppell High School. At this time,
the School District requests a variance to this anticipated requirement, to
delete the fire sprinkler system from the gymnasium portion of the new
High School. This request is being made because of the following special
conditions and reasons:
The School District is very concerned about possible ~amage
b a wood gymnasium floor brought about by the installation
of a fire sprinkler system. A malfunction of the sprinkler
system would be possible in this type of facility for a number
of reasons; the most common of which would be a mechanical
malfunction which is typical of all sprinkler systems. There
is also the possibility of damage brought about by vandalism or
horseplay by students. The District has contacted their insurance
agent on this matter, and it is their understanding that the
deletion of a sprinkler system from this space would have little
affect on the insurance premiums they pay. This would indicate
that the insurance carrier, an institution well versed in casualty
loss, does not consider this to be a major concern.
We would also like to point out that the gymnasium will be ~
separated from the remainder of the building by a one-hour fire
separation wall, and that all of the mechanical ductwork entering
the gym from adjacent mechanical lofts will have smoke detectors
incorporated into the general fire alarm system. This is mentioned
since the greatest potential for fire damage would be related to
the mechanical system for the gymnasium space.
