Fe a t u r es, Catalog Logic and Options
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.
Ballasts
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.
Cir cuitry
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).
Exam Light
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).
Switc hing Contr ols
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).
Other Options
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
MPWA
Accessories
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)
Maint enance
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.
