MPWA
Fe a t u r e s , C a t a l o g L o g i c
a n d O p t i o n s
The MPWA features a reflector
system in the lower optical
compartment that facilitates two
tasks-reading and patient
examination.
The MPWA is used for obtaining
maximum efficiency while
providing cut off and glare control
to the remaining of the room’s
surroundings. With the push of a
switch, the upper lamp of the
lower compartment can be
energized to aid in evaluation of
the patient. The reflector works
with this lamp by providing
maximum output and control of
light over the patient’s torso for
examination or any other tasks
that may be necessary. The
effectiveness of this lamp/optical
system is maximized by its
flexibility in utilizing these two
lamps in conjunction or
separately.
B a l l a s t s
Fixtures are supplied standard
with electronic ballasts.
Magnetic, energy saving ballasts
are available with T8 lamps only
(LEOC8). An optional radio
interference filter (RIF) is
commonly used with magnetic
ballasts to reduce radio
interference with sensitive
equipment.
C i r c u i t r y
All individual input circuits will be
supplied with a quick disconnect
module (QDM) to facilitate ease of
maintenance and installation.
GCO
(grounded convenience
outlet) and
FNL
(fluorescent night
light) options are commonly run
on separate circuits. Each will be
supplied with a QDM, separate
from the primary lamp sources
and will require additional
switching and wiring by others.
All primary lamp sources are
wired onto the same circuit unless
specified otherwise (See
Switching Controls).
E x a m L i g h t
EXL Feature-
This standard feature
includes a specular reflector that
separates the two lower lamps.
The upper lamp in the lower
compartment is for use as an
exam light. The lower lamp in the
same compartment is intended for
reading and other ordinary tasks.
(The upper lamp in the lower
compartment is switched
independently of the primary
lamp system via a rocker switch;
add "R" for installation on right
side of unit,
EXLR;
add "L" for
installation on left side of unit,
EXLL
).
S w i t c h i n g C o n t r o l s
No switching option specified
implies the fixture will ship with
input leads left unwired for switch
wiring to be completed in field as
desired.
PS4-
4-position pull chain
switching. All primary lamps
(except EXL lamp) wired in
sequence by following: lower
lamps on, upper lamps on, all
lamps on, all lamps off. (120V
only, brushed nickel finish,
installed in center of unit on
bottom of power tray).
PS1D-
2 position pull chain switch,
controls the bottom lamp
compartment only (except EXL
lamp). (120V only, brushed nickel
finish, installed in center of unit
on bottom of power tray). Upper
lamp compartment is on a
separate circuit to be wired and
switched at wall or as desired.
LVCP-
Low voltage controller,
patient controlled. Mounted
inside unit for patient control of
all primary lamps-upper and
lower lamp compartments. Wired
in sequence for lower lamp on
(except EXL lamp), upper lamps
on, all lamps on, all lamps off.
Includes 1/4" phone jack type
receptacle centered in bottom of
wire way for input control by
others or may be used with
accessory
MBC
-momentary
button cord switch (See
accessories).
LVCF-
Low voltage controller,
facility controlled. Mounted
inside unit, controller is left
unwired for specific wiring/control
requirements of facility. Includes
1/4" phone jack type receptacle,
centered in bottom of wire way
for input control by others or may
be used with accessory
MBC-
momentary button cord switch
(See accessories).
O t h e r O p t i o n s
EBP-
The emergency battery pack
option is a good candidate for
facilities that do not have
emergency generator systems.
Test switch and indicator light will
be installed on top of unit in
middle of the power tray.
FNL-
Fluorescent night-light, 2-pin
(G23 Base), 7 or 9w twin tube
lamp installed in center of upper
compartment of fixture, uses a
magnetic ballast. FNL is wired on
a separate circuit. (Lamps by
others).
GCO-
Grounded convenience
outlet. White in color on units
with white finish; black in color on
all other finish options, wired on a
separate circuit. (120V only,
maximum 10 amps, installed on
bottom right side facing unit; add
"L" for installation on left side of
unit,
GCOL
).
GLR-
Fuse and holder, wired to
primary lamp circuit only.
NRL-
White LED nurses chart
reading light. Directed so as not
to discomfort the patient.
Switched separately via rocker
switch, both lamp and switch
located on the bottom of the
power tray. White in color on
units with white finish; black in
color on all other finish options
(120V only, installed on either the
right or left side, facing unit; add
"R" for installation on right side of
unit,
NRLR
; add "L" for installation
on left side of
unit,
NRLL
).
RIF-
Radio interference filter, for
use with magnetic T8 ballast only.
(1 per ballast).
SF1-
Tamper-proof Torx™-head
fasteners
Ac c e s s o ri e s
MBC-
Momentary button cord
switch. May be used with LVCP or
LVCF options to control lamps. All
units are wired at factory as
specified per catalog logic (See
Switching Controls).
VRSD-
Torx™-head tamper-proof
screwdriver (for use with SF1
option)
M a i n t e n a n c e
The MPWA is designed to
facilitate ease of maintenance.
Its three part assembly makes for
efficient installation. No tools are
required for relamping or
substituting electrical power trays
on standard fixtures. When
maintenance is required, simply
loosen the two end thumbscrews
and slide the partial clamshell,
front lens assembly forward and
off. The lamps and power tray
will now be accessible and can be
removed by quarter-turn
fasteners. This assembly hangs
suspended on the back pan while
it is easily disconnected via a
quick disconnect power
connector. Spare units can speed
the maintenance process by easily
substituting the power tray, thus
causing less disruption in the
room.
