Department of Facilities Management 26 52 00 Emergency Lighting
SECTION 26 52 00: EMERGENCY LIGHTING
1.
GENERAL
A.
This section details the basis of design for building
emergency lighting in new construction and existing facility
renovations.
B.
In addition to code–required locations, provide emergency
lighting in large classrooms, places of assembly, public
bathrooms, serving assembly spaces, research labs, central
building mechanical and electrical rooms, and any areas where
hazardous tasks are performed.
C.
Selection of lighting fixtures for normal and emergency use
shall minimize the number of different lamp types utilized and
required to be stocked by Operations staff.
D.
Emergency egress lighting to be powered by the Life Safety
branch automatic transfer switch (ATS) in buildings where a
standby generator is installed. In buildings where no
generator or Life Safety branch circuits are installed,
utilize central inverter(s) or emergency lighting battery
units.
E.
Life Safety & Egress Lighting:
1.
Residential housing (multi-family apartments)
i.
Provide a central inverter or central battery unit(s)
for service to local emergency heads and exit signage.
ii.
For the latter, minimize the quantity of individual
battery units installed (e.g. to provide a single
battery unit to serve the overall floor level or
stairwell landings).
2.
Small office, classroom, residence hall and other
non-critical facilities
i.
Provide central inverters for powering of required
egress lighting and exit signage.
ii.
In larger facilities, multiple inverters (e.g. one
inverter per floor) are allowed.
F.
Fluorescent emergency ballasts (Bodine brand) are not allowed.
G.
Spare Parts:
1.
Provide spare fixtures, lamps and ballasts in quantities
equal to 5% of the amount used on the project.
2.
Provide lockable space within the building for the storage
of spare lamps and spent lamps to be recycled.
3.
For special lamps, provide attic stock of six spare lamps.
H.
Emergency Circuit Switching:
1.
May vary depending on type of facility and will be
confirmed during design.
2.
Certain facilities, such as research and lab, typically
require 24/7 unswitched control of emergency lighting,
otherwise known as night light circuits.
3.
Large assembly spaces with central lighting controls
typically require emergency lighting to be controlled
on/off/dimmed. Provide override controls such as transfer
relays, to override “on” emergency lights in the event of
a power failure.
4.
Small assembly spaces where it is desired to normally
switch emergency lighting “off” for presentations, etc.,
provide override controls such as transfer relays, to
override “on” emergency lights in the event of a power
failure.
2.
BATTERY UNITS
A.
Where installed, to be 12-volt type and have built-in
self-test features with alarm on test failure.
B.
Avoid the use of multiple battery units; centralize emergency
lighting power supply with a single battery unit (with zone
relays for multiple circuits) wherever possible.
C.
Battery units shall have maintenance-free batteries.
D.
Approved Manufacturers:
1.
EmergiLite
2.
Beghille
3.
INVERTERS
A.
Must match building utilization voltage for lighting circuits,
and avoid the use of step-down transformers.
B.
Provide inverter with local distribution panel on larger size
units for individual breaker control of emergency lighting
circuits, main input circuit breaker, integral bypass switch
to allow for system testing and battery replacement without
affecting downstream loads, and built-in self-test features
with alarm on test failure.
C.
Size inverter with 15% spare capacity to allow for future
system connections.
D.
Approved Manufacturers:
1.
Meyers
2.
EmergiLite
3.
Beghille
4.
EXIT SIGNS
A.
Signs to be light emitting diode (LED).
B.
Self-luminous type exit signs are not acceptable.
C.
Residence Halls:
1.
Install with sign recessed or with sign back mounted flush
to the wall or building surface.
2.
Do not install with ceiling canopy or side mount
connection to wall. Consider triangular plywood backboards
for signs mounted on walls where ceiling height allows.
D.
Signs in retrofit applications to match existing installed
building exit signs for style and configuration.
E.
Connect exit signs to central inverter circuits or to output
of battery units for standby power source. Avoid use of exit
signs with integral batteries.
