3. INSTALLINg ThE ThREADED BODy TEST SWITCh (TBTS)
Select a convenient location on the side of the fixture so that the TBTS can be seen after installation. Allow for
proper clearance and drill or punch a 1 /
2
″ hole. Remove the nut from the TBTS. Push the TBTS housing into the
1 /
2
″ hole and secure with the nut. Connect the LED wires from the unit to the TBTS (Red/Black or Red w/tag to
Red, and White/Red to White). NOTE: For proper operation, use only the test accessories provided with the unit.
See Page 1 of the Instruction Manual.
4. WIRINg
A. The I-42-L and A.C. ballast must be on the same branch circuit.
B. The I-42-L requires an unswitched A.C. power source of either 120 or 277 volts; therefore, when used with
switched fixtures, the I-42-L input must be wired ahead of the switch.
C. Refer to the wiring diagrams on the back page for the proper wiring. For wiring diagrams of ballasts not shown,
consult our customer service.
5. LABELS
Attach the appropriate labels adjacent to the TBTS. 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 ser-
vice the fixture.
6. COMPLETINg INSTALLATION
A. When the installation is complete, switch the A.C. power on and join the I-42-L unit connector.
B. Replace the ballast cover, fixture lens and other fixture hardware.
OPERATION
Normal Mode – A.C. power is present. The A.C. ballast operates the fluorescent lamp(s) as intended. The I-42-L 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-L 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-L switches the system back to the Normal Mode and resumes battery charging. See
page 1 of the Instruction Manual.
TESTING & MAINTENANCE
Pressing the red lens on 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-L unit. After releasing the TBTS,
the fixture 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
test switch. Allow a 24 hour charge before conducting a one hour test.
The
I-42-L 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 or two lamps 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.
