ITM
A proposed change for the 2023 edition would extend the
time that qualified personnel must respond to an abnormal
pump condition during a remotely monitored automatic
test from five minutes to four hours.
cover plates in a sprinkler system be
removed every five years to check for
hidden issues. This is a significant
increase in scope from the type of
inspections required in past editions of
NFPA 25.
Previously, a typical sprinkler system
inspection was limited to a visual
inspection from the floor. Removing
cover plates would require additional
equipment, such as tools and a ladder
or lift. Even though this type of inspection
would require more work on the
part of the inspector, this new requirement
is proposed to uncover hidden
issues such as leaks, damaged sprinkler
heads, or improper cover plate installation.
Any of these issues can cause
premature operation of a system or
cause the system to be ineffective when
it does operate.
70 | NFPA JOURNAL * SUMMER 2022
A certified amending motion has
been filed on this proposed requirement
that seeks to have it removed
from the standard. Some have argued
that there is a lack of technical substantiation
for this requirement, and
that the five-year inspection time
frame was arbitrary. It has also been
stated that the need for additional
tools and ladders or lifts places an
unnecessary expense on the inspector.
This will be discussed during the technical
session at the NFPA Conference
& Expo®
in June.
Change to testing
frequencies for fastresponse
elements and
dry sprinkler heads
For this proposed change, the technical
committee has increased the initial
time frame for some types of sprinkler
heads until they are subject to field service
testing by an approved laboratory.
Sprinkler heads using fast-response elements-except
for early suppression, fast
response sprinklers, and control-mode
special application sprinklers-will now
require testing after they have been
installed for 25 years instead of 20, and
dry sprinkler heads will need testing
after 20 years instead of 15.
Dry sprinklers were first introduced
about 30 years ago, and fast-response
sprinklers have been around for about
50. When both of these sprinkler types
arrived, the frequency of testing was
kept low because it was not known how
they would perform over time. Now that
they have been in place for a while, a
history of test data has accumulated to
support changing the testing frequency.
