5. INSTALLING THE TEST SWITCH

The test switch should be mounted on the ballast channel cover of a recessed troffer, or on the side of a strip fixture, preferably adjacent to the charge indicator. Drill or punch a 1/2mounting hole.

6.WIRING THE A.C. INPUT

A.The FPS-HLand A.C. ballast must be on the same branch circuit.

B.The FPS-HLrequires an unswitched A.C. power source of either 120 or 277 volts. Select the proper voltage lead and cap the unused lead.

C.When the FPS-HLis used with a switched fixture, the A.C. input to the FPS-HLmust be connected ahead of the fixture switch. Refer to Illustration 3 for switched and unswitched fixture wiring diagrams.

7. LABELS

Attach the appropriate labels adjacent to the Test Switch and Charge Indicator. Annotate Re-lamping label for lamp type and wattage. The Caution and the Re-lamping labels must be on the fixture in a readily visible location to anyone attempting to service the fixture.

8. COMPLETING INSTALLATION

When the installation is complete, switch the A.C. power on and join the FPS-HLunit connector.

OPERATION

Normal Mode – A.C. power is present. The A.C. ballast operates the fluorescent lamp(s) as intended. The FPS-HLis in the standby charging mode. The Charge Indicator will be lit providing a visual indication that the battery is being charged.

Emergency Mode – The A.C. power fails. The FPS-HLsenses the A.C. power failure and automatically switches to the Emer- gency Mode. One or two lamps are illuminated, at reduced output, for a minimum of 90 minutes. When the A.C. power is re- stored, the FPS-HLswitches the system back to the Normal Mode and resumes battery charging. See page 1 of the Instruction Manual.

TESTING & MAINTENANCE

Initial Testing – Allow the unit to charge approximately 1 hour, then conduct a short discharge test. Allow a 24 hour charge before conducting a one hour test.

The FPS-HLis a maintenance free unit, however, periodic inspection and testing is required. NFPA 101, Life Safety Code, outlines the following schedule:

Monthly – Insure that the Charge Indicator light is illuminated. Conduct a 30 second discharge test by depressing the Test Switch. One lamp or two lamps should operate at full or reduced output, depending on your configuration.

Annually – Insure that the Charge Indicator light is illuminated. Conduct a full 11/2 hour discharge test. The unit should operate as intended for the duration of the test.

“Written records of testing shall be kept by the owner for inspection by the authority having jurisdiction.”

SERVICING SHOULD BE PERFORMED BY QUALIFIED PERSONNEL.
