4) Patient room/exam room fixtures shall be multi-function lights and the exam<br />

room shall be indirect.<br />

5) Diagnostic and treatment areas shall use 2’ x 4’ fluorescents and electronic<br />

ballasts (or special fittings as required by such things as MRI)<br />

6) Dimmable down lights may be incandescent for clinical applications.<br />

7) Non-dimmable down lights shall be fluorescent.<br />

BSRV 6.2.8 MOTORS AND STARTERS<br />

Motors ¾ hp and larger shall be 3-phase, using the highest available appropriate<br />

voltage. All such motors shall be equipped with permanently lubricated bearings.<br />

All motors shall be NEMA Premium Efficiency type, complying with the requirements <strong>of</strong><br />

the latest edition <strong>of</strong> NEMA MG 1, with a service factor <strong>of</strong> 1.1 or better. All motors<br />

between 1 and 200 hp shall exceed these standards where possible and economically<br />

justified.<br />

Sheaves and V-belts on belt driven equipment shall be rated for 150 percent <strong>of</strong> motor<br />

horsepower. Belts shall be guarded to provide safety protection, ventilation and cool<br />

operation. Solid sheaves and band belts shall be used to minimize vibration in multiple<br />

V-belt driven equipment.<br />

All motors, except light-duty fractional horsepower motors, shall be provided with<br />

motor controllers. Controllers shall provide under-voltage protection when used with<br />

momentary contact control devices and under-voltage release when used with<br />

maintained contact control devices. Controllers shall also provide phase-loss (single<br />

phasing) protection.<br />

A lockable disconnecting means shall be provided at all motor locations within sight (50<br />

ft.) and reach <strong>of</strong> motor location. All motors and their disconnecting means shall be<br />

clearly marked to identify the motor that the disconnect serves. Circuit breakers shall<br />

not serve as motor disconnecting means.<br />

Variable Frequency Drives:<br />

All motor variable frequency drives (VFDs) shall meet IEEE standard 519. The VFD shall<br />

be able to communicate with Building Automation System controls, through BACNET or<br />

other acceptable communications protocol. Where multiple VFDs are fed from the<br />

same panelboard or MCC, the contractor shall provide a harmonic analysis, at that<br />

point, to show compliance with IEEE 519. Include analysis with drive submittals.<br />

VFDs shall be pulse width modulated (PVM) type using IGBT technology. VFDs shall be<br />

provided with by-pass isolation switches.<br />
