A. The ICE-420-EM-A and A.C. ballast must be on the same branch circuit.
B. The ICE-420-EM-A requires an unswitched A.C. power source of either 120 or 277 volts; therefore, when
used with switched fixtures, the ICE-420-EM-A 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.
NOTE: The ICE-420-EM-A will require a maximum power input of 100 watts when the internal heating element is
active
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
When the installation is complete, switch the A.C. power on and join the ICE-420-EM-A unit connector.
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(s) and lamp(s) to provide the emergency function. It can also be wired for emer-
gency only operation.
Normal Mode – A.C. power is present. The A.C. ballast operates the fluorescent lamp(s) as intended. The ICE-420-EM-
A 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 ICE-420-EM-A 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 ICE-420-EM-A 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 ICE-420-EM-A 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
TBTS. The TBTS light will go out and the fluorescent tube will be illuminated. When the ICE-420-EM-A is used in fix-
tures 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
ICE-420-EM-A 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.
