6. LABELS
Attach the appropriate labels adjacent to the LPTS. 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.
7. COMpLETINg INSTALLATION
When the installation is complete, switch the A.C. power on and join the ISD-420-EM-B unit connector.
OPERATION
Normal Mode – A.C. power is present. The A.C. ballast operates the fluorescent lamp(s) as intended. The ISD-420-
EM-B is in the standby charging mode. The LPTS will be lit (green) providing a visual indication that the battery is fully
charged and (red) when battery is currently charging.
Emergency Mode – The A.C. power fails. The ISD-420-EM-B senses the A.C. power failure and automatically switches
to the Emergency Mode. One lamp is illuminated, at reduced output, for a minimum of 90 minutes. When the A.C. power
is restored, the ISD-420-EM-B switches the system back to the Normal Mode and resumes battery charging. See page
1 of the Instruction Manual.
TESTING & MAINTENANCE
pressing and releasing the LPTS initiates a 30-second test by interrupting power to the designated A.C. ballast and
causing the unit to run in emergency mode. The designated emergency lamp is now being lit by the ISD-420-EM-B
unit for a 30-second test. After the 30-second test has completed, the fixture returns to normal operation. To simulate a
“BLACK OUT” use the circuit breaker to turn off A.C. power to the fixture.
Initial Testing – Allow the unit to charge approximately 1 hour, then conduct a short discharge test. Allow a 72 hour
charge before conducting a one hour test.
The
ISD-420-EM-B is designed to automatically conduct both 30-second and 90-minute tests at regular intervals every
26 to 28 days. Automatic Testing is outlined in the following schedule:
Automatic Monthly Testing – The ISD-420-EM-B will automatically conduct a 30 second test once. If the ISD-420-EM-B
encounters a problem, the LPTS will flash. See Table below for diagnosis.
Automatic Annual Testing – The ISD-420-EM-B will automatically conduct a 90 minute test every twelve months. If the
ISD-420-EM-B encounters a problem, the LPTS will flash. See Table below for diagnosis.
To insure accurate testing, the
ISD-420-EM-B will not conduct any scheduled automatic tests for a period of 72 hours
after the unit has discharged, regardless of reason, for more than five minutes.
Manual Testing - Manual Testing can be performed on the ISD-420-EM-B at any time, provided the unit is fully
charged, by pressing and releasing the LPTS (see above). Manual Testing will not interfere with the automatic testing
schedule of the ISD-420-EM-B and will display the same diagnosis indicators as automatic testing.
