selected to match or coordinate with adjacent pole mounted fixtures.
14. Page 226, Section 105, E, 2, revise as follows:
2. Bollard type fixtures shall be approved by TCCD.
15. Page 226, Section 105, E, 3, revise as follows:
3. The preferred method of floodlighting for building facades is by building mounted or pole mounted
fixtures in lieu of ground-mounted fixtures. If ground-mounted fixtures are installed, recognize
that the fixture is a high-temperature hazard and place it where it is not readily accessible by
the public, minimize glare to pedestrians and minimize additional effort by grounds maintenance
personnel.
16. Page 227, delete Section 105, F, and replace with the following:
F. Lamps and Ballasts
1. Reference TCCD Lighting Playbook for standard exterior fixture schedules.
2. Sodium vapor, mercury vapor and incandescent lamps shall not be used.
17. Page 228, Section 105, J, 10, revise as follows:
10. Type MC cable may be used only for lighting whips and in existing walls. Type AC or BX cable is
not allowed.
18. Page 229, Section 105, J, 16, revise as follows:
16. Minimum size for raceways: 3/4” minimum for panel homeruns and minimum ½” within walls.
19. Page 229, Section 105, L, 1, revise as follows:
1. Reference the current version of the TCCD Lighting Playbook and its standard fixture schedule.
Illumination foot candle levels shall be based on the recommended values given in the IESNA
Handbook and allowances prescribed by the energy codes.
20. Page 231, Section 105, L, 8, f, revise as follows:
f. TCCD has standardized on equipment manufactured by NLight for standalone and system
occupancy sensors. If the room is equipped with NLight controls then the occupancy sensor
will be an NLight unit attached to the NLight network and programmed into the campus
NLight system along with touch stations for controlling the lights.
21. Page 231, Section 105, L, 10, a, revise as follows:
a. The design professional shall study, when available, record, as-built, and/or renovation
drawings to verify existing conditions. Every attempt should be made, short of destructive
demolition, to verify existing conditions. Reuse lighting/mechanical circuits, for new lighting
fixtures/mechanical equipment, when existing lighting fixtures/mechanical equipment has
been removed. Update panel schedules after renovation work is complete, schedules shall be
type written.
22. Page 231, Section 105, L, 11, a, revise as follows:
a. Provide circuit identification for electrical equipment, receptacles and circuits for new and
retrofit work.
23. Page 231, after Section 105, L, 8, f, add the following:
g. Because of the ability for one circuit to power lighting in multiple classrooms, the design
shall incorporate key switches located above the entrance to the classroom that can remove
power from that classrooms lighting circuit. This will avoid repairs in one classroom from
taking a whole bank of classrooms out of service.
24. Page 231, Section 105, L, 9, a, revise as follows:
a. The preferred method to power egress lighting is to provide fixtures supplied from a circuit
in an emergency panel fed by the emergency power source, centralized inverter system or
generator as directed by TCCD.

28 ELECTRONIC SAFETY AND SECURITY/ FIRE SYSTEMS
3. Page 249, Section 111, C, 2, revise as follows:
2. Fire Alarm System – SimplexGrinnell 4100ES connected to Simplex TrueAlarm network and UL
TrueSite Workstation.
4. Page 249, after Section 111, D, 1, b, add the following:
c. Design exceeding minimum Life-Safety and Fire code requirements: Fire alarm systems
installed in TCCD typically surpass minimum Life-Safety and Fire code requirements. TCCD’s
intent is to utilize fire alarm systems to provide early warning to building occupants and
emergency responders, allowing them to take action before more serious fire conditions
activate fire sprinklers. Additionally, TCCD’s fire systems provide the backbone for a district-
wide, central Emergency Communications Systems, for all types of urgent public notification.
Both of these criteria require additional alarm sensing and public-notification equipment.
5. Page 250, after Section 111, E, 1, d, add the following:
e. Fire alarm wiring in conduit shall have a minimum 3/4” conduit size.
6. Page 251, Section 111, E, 5, a, revise as follows:
a. Heat detectors shall be provided in staff breakrooms, central utility plant machine rooms,
wood shops, metal shops, laboratories and in other areas in which smoke or visible vapors
are generated during normal operations.
7. Page 252, after Section 111, E, 8, a, 4), add the following:
5) Where a single FACP serves multiple buildings, satellite buildings shall have an
annunciator panel.
6) All work in new and existing (renovation/demolition) facilities shall include updating TCC
fire alarm graphics to show new, relocated and/or removed fire alarm devices. Graphics
features shall match (or exceed) performance of Simplex UL - Certified TrueSite(R)
Workstation.
