Section 112.250 General Requirements for Carbon Monoxide
Detectors or Detection Systems in Public Schools
a) For public
schools designed on or after January 1, 2016, a carbon monoxide detection
system or carbon monoxide detectors installed to achieve compliance with the
School Code and this Part must be monitored by any required fire alarm system
and must be permanently powered by the building's electrical system.
b) A
carbon monoxide detection system constructed and installed pursuant to this
Section and its components must be listed in accordance with the applicable UL
standard for the purpose for which it is used and must be cross-listed in
accordance with the applicable UL standard with the panel to which it is
connected.
c) Carbon
monoxide detectors shall be listed in accordance with UL 2075, incorporated by
reference in Section 112.180.
d) Combined
carbon monoxide and smoke detectors installed in carbon monoxide detection
systems shall be an acceptable alternative to carbon monoxide detectors
provided the combination detectors are listed in accordance with UL 2075 and UL
268.
e) Carbon
monoxide detection system or carbon monoxide detector components must be
installed and maintained in accordance with the manufacturer's published instructions
and NFPA 720, incorporated by reference in Section 112.180, except that the
location and the frequency of inspection and testing of carbon monoxide
detectors shall be as prescribed in Section 10‑20.56(b) or 34-18.49(b) of
the School Code, as applicable.
f) All
carbon monoxide detection systems and carbon monoxide detectors must have an
audible alarm signal that is distinctive from other alarm signals and is a
four-pulse temporal pattern as prescribed in NFPA 720.
g) Carbon
monoxide detection systems or carbon monoxide detectors must have occupant
notification throughout the building, except that the occupant notification
zone may be limited to the area where the carbon monoxide alarm signal was
initiated where the signal is transmitted to a constantly attended location
on-premise or off-premise where response action can be taken.
h) Signals
from carbon monoxide detection systems and carbon monoxide detectors
transmitted to a fire alarm system shall not transmit a fire alarm signal.
