Appendix C: How to Build a Title 24 Compliant System

California Title 24 Part 6 specifies mandatory requirements for enclosed parking garages. A compliant gas de-
tection system can be constructed from the Honeywell Analytics 301C24 version controller and E³Point Net-
work gas sensor. This section describes how to configure the 301C controller to accomplish this.

Requirement: Section 120.6(c)4 "CO concentration at all sensors is maintained at 25 ppm or less at all times."
Solution: Create an event for each group such that if one or more sensors report a concentration greater than
25 ppm the event is activated.
Requirement: Section 120.6(c)7 A-D "CO sensor shall be:
A. Certified by the manufacturer to be accurate within plus or minus 5 percent of measurement.
B. Factory calibrated.
C. Certified by the manufacturer to drift no more than 5 percent per year.
D. Certified by the manufacturer to require calibration no more frequently than once a year.
Solution: Use Honeywell Analytics E3Point Network Gas Monitor with carbon monoxide cartridges.
Requirement: Section 120.6(c)7Ei "The CO sensor shall be monitored by a control system. If any sensor has
not been calibrated per the manufacturer's recommendations within the specified calibration period, the sensor
has failed."
Solution: Use E3Point carbon monoxide sensors, which require calibration every 12 months. Create an event
to activate if time since calibration (TSC) is 12 months. Configure this event to activate fans and the alarm de-
vice.
Requirement: Section 120.6(c)7Eiii "The CO sensor shall be monitored by a control system. During occupied
periods the system compares the readings of sensors in the same proximity zone, e.g. if the 30-minute rolling
average for any sensor in a proximity zone is more than 15 ppm above or below the 30-minute rolling average
for other sensor(s) in that proximity zone, the sensor has failed."
Solution: Create an event to activate if the concentration reading of any sensor in a group is an outlier deviat-
ing by 15 ppm for longer than 30 minutes.

Description
A region of a garage containing several sensors.
Gas readings in the region are presumed to be
similar because of free air circulation.
A notification from the gas detection system that
the system is not working correctly.
