Series C65 | 12.07.10
UL1008 - EMERGENCY LIGHTING TRANSFER CABINET
Series C65 for 120V circuits with Type 3 Emergency feed
SPECIFICATIONS
GENERAL: The Emergency Lighting Transfer Cabinet shall
provide automatic transfer of branch circuits from normal to
emergency power when normal power fails. Each cabinet
shall consist of a control module and a quantity of contactor
modules interconnected to provide complete, automatic
protection.
Under normal conditions, designated lighting loads are
controlled by dimmer racks or relay panels. The ELTC
continuously monitors the power feed to one or more of
these dimmer racks or relay panels. In the event of a power
failure to any or all of these devices, the ELTC will transfer
the designated emergency loads to emergency power. A fire
alarm signal or other external input can also be used to
trigger a transfer to emergency. If both normal and
emergency power sources are absent, the ELTC shall
remain functional for a minimum of 10 seconds before
powering down.
Cabinets shall be provided with mounting ears including
sealing washers to maintain the NEMA rating of the
enclosure.
Cabinet enclosures shall be 24” wide x 10” deep. In order
to minimize requirements for mounting space, enclosures
shall be available in four heights (24”, 36”, 48” & 60”).
The ELTC shall be approved for use to provide egress
lighting as defined in ANSI / NFPA 101, the Life Safety
Code.
The ELTC shall contain a test switch, a Normal indicator
LED (Green) and an Emergency indicator LED (Red). When
the Green LED is constant, it will indicate that the cabinet
is in normal mode. When the Red LED is constant, it will
indicate that loss of normal power has caused the cabinet to
transfer to emergency mode. When the Red LED is flashing,
it will indicate that the cabinet has been forced to
emergency mode by an override signal such as a test switch
or a fire alarm input. When the Green LED is flashing, it will
indicate that at least thirty days have passed since the ELTC
has been tested. After the cabinet has been tested, the
maintenance monitor will be reset and the Normal indicator
will be constant for another thirty days.
The ELTC shall be listed and labeled as ANSI / UL1008
Transfer Switch Equipment and shall comply with ANSI /
NFPA 110 Standard for Emergency and Standby Power
Systems.
The ELTC shall satisfy all requirements of the NEC (NFPA
70) as defined in:
Article 700 – Emergency Systems
Article 701 – Legally Required Standby Systems
Article 702 – Optional Standby Systems
Section 518.3(C) – Assembly Occupancies
Section 520.7 – Theatres and Similar Locations
Section 540.11(C) – Motion Picture Projection Rooms
The ELTC shall be a self contained system for up to 32
circuits at 20 amps and available for 120/240 or 120/208
power. Units shall be available in configurations to
accommodate either; multiple, two-wire, emergency feeds
or for a single, main, emergency feed.
ENCLOSURE: The ELTC shall be constructed in a NEMA
4/12 enclosure finished in a black polyester powder paint.
The cabinet shall have a removable door with hidden hinges
for a clean, aesthetic appearance. Doors shall be equipped
with a seamless gasket to prevent dust or other contaminants from entering the cabinet. Material shall be 14 or 16
gauge steel with seams continuously welded and ground
smooth.
The enclosure shall provide power distribution and branch
circuit protection for all emergency power circuits.
The enclosure shall be separate and independent of all other
equipment. In no instance shall the ELTC be enclosed in a
dimmer rack or in an enclosure containing other equipment.
The system shall be provided with an approved overlay
mounted on the front of the enclosure, stating, “EMERGENCY LIGHTING TRANSFER CABINET”.
The enclosure shall be provided with an approved label
indicating that the system is UL1008 LISTED.
Emergency power must be present for the cabinet to
transfer to emergency mode. If a transfer is triggered either
by loss of normal power or from an external signal and if
emergency power is not present, the cabinet will enter
standby mode. In standby mode, both the Green LED and
the Red LED will be OFF. When emergency power comes on
line, it will immediately pass through to the loads and the
Red LED will come ON. If emergency power does not come
on line and normal power is restored (or the test switch is
released), the cabinet will return to Normal mode and the
Green LED will come ON.
OPERATION: The voltage of each phase of the normal
source shall be monitored, with the transfer from normal to
emergency adjustable from 75% to 95% of the nominal
voltage. The factory setting for the dropout point shall be
75% of nominal voltage. The setting for return from
emergency to normal
power is factory set at 80% of nominal. The system also
monitors for the presence of emergency power. If
emergency power is not present, the cabinet will not
transfer loads from normal to emergency.
The control module shall provide for time delays for both
the transfer to emergency power and the transfer from
emergency back to normal power. The transfer from normal
to emergency is set at the factory at 0 seconds. The time
delay for return to normal from emergency power is set at
the factory at 3 seconds. This setting is field adjustable up
to 99 minutes in 1 second increments.
Control power for all logic and transfer functions shall
always seek the acceptable power source. This shall prevent
the system from locking up in one position if either of the
power sources is available, regardless of the sequence of
failure events.
An isolated signal input shall be provided for connection to
the facility fire alarm. If connected to the fire alarm and if
emergency power is present, the ELTC shall automatically
transfer the loads to emergency when the fire alarm is
activated.
CONTROL CIRCUIT: The control circuitry shall be 24VDC.
Interfacing relays shall be covered, industrial control grade.
Provisions for optional remote signal, fire alarm and other
input or output signals shall be incorporated into the control
circuit.
TRANSFER POLES: The switch shall be electrically
operated and mechanically held (maintained). The switch
shall be positively locked and unaffected by voltage
variations or momentary outages so constant contact
pressure is maintained and temperature rise at the contacts
is minimized. All switch main contacts shall be silver-plated.
Overload and endurance testing of the transfer switch shall
comply with UL1008 Tables 25.1, 25.2, 27.1, and 27.2 for
mixed loads.
COORDINATION: Larger upstream breakers cannot be
tripped by downstream branch circuit faults. Switch
contacts shall withstand transfer without welding, with 180º
phase displacement between Normal and Emergency power
sources, both sources energized and with 80% load.
Transfer switch contacts shall be rated for mixed loads,
including electric discharge lamps and tungsten filament
lamps.
TYPE 3
A. DIMMER BANK/RELAY PANEL: All lighting
circuits are controlled through the dimmer or relay
panel using low voltage controls. When normal
power is present, circuits designated as “emergency
circuits” respond to the same controls as the
non-emergency circuits.
B. EMERGENCY LIGHTING TRANSFER CABINET
(ELTC): The circuits which serve as emergency
lighting are routed through a UL1008 ELTC which
continuously monitors the input power to the
dimmer/relay panel. If normal power to the
dimmer/relay panel fails, the ELTC transfers both
the hot and the neutral conductors of each circuit to
the emergency power source. This automatically
energizes the emergency lighting fixtures.
C. TYPE 3 EMERGENCY INPUT POWER: The
Type 3 emergency power feed to the transfer
cabinet consists of a single, 3PH, 4 wire + ground
120/208VAC circuit. Emergency power lands on
input lugs in the bottom of the cabinet. Internal
wiring with branch circuit protection distributes the
emergency power to the transfer relays.
D. NORMAL POWER FEED TO DIMMER/RELAY
PANEL: Typically, 120/208VAC, 3PH, 4W + Gnd.
or 120/240VAC, 1PH, 3W + Gnd. from the normal
building power (I) provides power to the dimmer/
relay panel.
E. & F. LIGHTING CIRCUITS: Lighting circuits
designated for emergency use (F) respond to low
voltage controls when normal power is present but
transfer to emergency the source (J) if normal
power fails. Lighting circuits that are not a part of
the emergency lighting (E) are connected directly to
the dimmer/relay panel.
G. SENSING FEED: The ELTC monitors normal
power through a sensing feed which taps the normal
power input to the Dimmer/Relay panel. Sense feed
wiring is typically 3 or 4 conductors #12AWG
depending on the normal power feed. Sensing feed
wiring must be protected by an over-current device.
H. SENSING WIRING CIRCUIT BREAKERS: To
protect the sensing feed wiring, a two or three-pole,
10A breaker may be mounted adjacent to the
dimmer/relay panel. This breaker and enclosure are
not provided with the ELTC, but may be added as an
option.
I. NORMAL POWER SOURCE: Normal building
power, typically from the public utility.
J. EMERGENCY POWER SOURCE: From a
generator, an inverter or from a secondary utility
feed.
