OPERATION
Normal Mode – A.C. power is present. The A.C. driver/ballast operates the lamp(s) as intended. The IIS-50-I is 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 IIS-50-I senses the A.C. power failure and automatically switches to
the
Emergency Mode
. The fixture is powered by the
IIS-50-I for a minimum of 90 minutes. When the A.C. power is
restored, the
IIS-50-I switches 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
IIS-50-I 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 Charge Indicator light is illuminated. Conduct a 30 second discharge test by depressing
the
Test Switch. Lamp(s) should operate at full output.
Annually – Insure that the Charge Indicator light is illuminated. Conduct a full 1
1
/
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.”
Replacing the Battery –
The integral, high temperature Ni-Cad battery is replaceable. To replace the battery, disconnect
the unit connector and remove both switched and unswitched A.C. power to the fixture. Open the lid to expose the battery. Un-
plug the battery connector and replace with part number F740500000. Recycle or dispose of the used nickel-cadmium battery
properly. Close the battery lid, resupply switched and unswitched A.C. power to the fixture and reconnect the unit connector.
SERVICING SHOULD BE PERFORMED BY QUALIFIED PERSONNEL.

3. INSTALLING THE CHARGE INDICATOR AND TEST SWITCH
The charge indicator and test switch are to be installed either within the AC fixture or in a single gang switch
box (not provided) adjacent to the fixture. A faceplate for accommodating the test switch and charge indicator is
included with the
IIS-50-I. Refer to Illustration 1.
Single Switch Box Installation - Cut a single gang switch box into the ceiling adjacent to the fixture. After
mounting the switch box, route test accessory leads from the junction box to the switch box via flexible conduit
(not provided). Complete connections within the switch box, observing proper polarity, and secure faceplate.
Refer to the Wiring Diagram on Page 4.
Integral Fixture Installation - Select a convenient location with proper clearance in the fixture where the test
components are visible and accessible after installation. Drill or punch a
1
/
2
″
hole. Push the
Charge Indicator
housing into the
1
/
2
″
hole until it is firmly locked in place. Connect the leads, observing the proper polarity. The
Test Switch should be mounted on the channel cover or on the side of the fixture, preferably adjacent to the
charge indicator. Drill or punch a
5
/
16
″
mounting hole. Refer to the Wiring Diagram on Page 4.
4. COMPLETING INSTALLATION
A. When the installation is complete, confirm that the AC Output Setting (Voltage Selector) switch is in the proper
position, then supply AC power.
Once AC Power has been applied, join the IIS-50-I unit connector.
The
Charge Indicator will illuminate indicating the presence of AC power and that the battery is being
charged.
B. Attach the appropriate labels adjacent to the
Test Switch and Charge Indicator. Affix the provided ‘
CAUTION
- This fixture provides more than one power supply output source
’ label in a location readily visible to anyone
servicing the fixture.
C. Allow the
IIS-50-I to charge for approximately 1 hour then conduct a short discharge test to confirm proper
operation. To conduct a long-term discharge test, allow the
IIS-50-I to charge for 24 hours. Refer to the “Opera-
tion” section for confirming proper operating performance.
