OPERATION

General – This unit is primarily designed to be used with compact fluorescent lamp downlight fixtures. It will wire in con-

junction with the existing A.C. ballast and lamp(s) to provide the emergency function. It can also be wired for emergency
only operation.
Normal Mode – A.C. power is present. The A.C. ballast operates the fluorescent lamp(s) as intended. The I-42-EM-R is
in the standby charging mode. The

TBTS will be lit providing a visual indication that the battery is being charged.

Emergency Mode – The A.C. power fails. The I-42-EM-R senses the A.C. power failure and automatically switches to

the Emergency Mode. One lamp or two lamps are illuminated, at reduced output, for a minimum of 90 minutes. When

the A.C. power is restored, the

I-42-EM-R switches the system back to the Normal Mode and resumes battery charging.

See page 1 of the Instruction Manual.

TESTING & MAINTENANCE

Pressing the

TBTS turns off the light on the TBTS and forces the unit into emergency mode, interrupting power to the

designated A.C. ballast. The emergency lamp is now being lit by the

I-42-EM-R unit. After releasing the TBTS, the fix-

ture returns to normal operation after a momentary delay. To simulate a “BLACK OUT” use the circuit breaker to turn off

A.C. power.
Initial Testing – Allow the unit to charge approximately 1 hour, then conduct a short discharge test by depressing the

TBTS. The TBTS will go out and the fluorescent tube will be illuminated. When the I-42-EM-R is used in fixtures with

more than one A.C. ballast, the second A.C. ballast is NOT de-energized with the

TBTS. It may, therefore, be advisable

to switch the A.C. fixture power off prior to depressing the

TBTS. Allow a 24 hour charge before conducting a one hour

test.
The

I-42-EM-R is a maintenance free unit, however, periodic inspection and testing is required. NFPA 101, Life Safety

Code, outlines the following schedule:
Monthly – Insure that the TBTS light is illuminated. Conduct a 30 second discharge test by depressing the TBTS. One
lamp should operate at reduced output.
Annually – Insure that the TBTS light is illuminated. Conduct a full 1½ 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.
