2. CONNECTING REMOTE EMERGENCY FIXTURES (FIGURE 1)
A. Connect remote emergency fixtures to the correct output leads. The color code is as follows: neutral is Gray, 120V
is Violet, and 277V is Yellow. All remote circuitry is to be wired in accordance with Article 700 of the National
Electric Code. Do not exceed the total rating of the
IIS-125. When making connections to the IIS-125, DO NOT
connect the Input Neutral (WHITE) to the Output Neutral (GRAY).
B. NORMALLY-OFF FIXTURES (only come on during power failure) - Connect the AC line input wire of the fixtures
to the appropriate output wires as above (120V or 277V). Connect the fixture Neutral input wire to the Neutral
output wire. Refer to
Figure 1.
C. NORMALLY-ON FIXTURES - Follow Step 2B above. Then select the proper voltage flying lead from the printed
circuit board (BLACK for 120V, ORANGE for 277V) and connect to the unswitched AC input line feeding the
transformer. Connect the Neutral (WHITE) flying lead coming from the printed circuit board to the unswitched AC
input neutral of the supply line feeding the input wires. Refer to
Figure 1.
D. FIXTURES ON LOCAL SWITCH (fixtures may be turned on and off locally, but will come on during power failure
regardless of switch position) - Follow Step 2B above. Connect the line side of the Switch to the unswitched
AC input line connected to the transformer. Connect the load side of the Switch to the proper voltage flying lead
from the printed circuit board (BLACK for 120V, ORANGE for 277V). Refer to
Figure 1. CAUTION: If connected
to 277 volt input, use a 277V rated switch. Failure to use the proper voltage switch may result in switch
failure, a shock hazard, an unsafe condition and equipment failure.
E. ALTERNATE FEED (all fixtures are supplied on normal from an alternate circuit) - Follow Step 2B above. Then extend
alternate AC input to the proper voltage flying leads from the printed circuit board (BLACK for 120V, ORANGE for
277V). If a local Switch is present, connect the alternate AC input to the Switch, then connect the proper voltage
flying leads from the printed circuit board to the load side of the Switch as in Step 2D. Refer to
Fig 1.
Consult the IIS-125 Application Notes for connecting the unit to specific lighting loads. Application Notes are
available on the internet or through Customer Service.
F. Connect the Fixture Supply Ground to the IIS-125 Ground.
CAUTION: Before proceeding to Wiring Step 3, make sure that all unused wires are properly capped. Failure
to do so may result in an unsafe condition and equipment failure.
DO NOT ENERGIZE THE CIRCUIT AT THIS TIME.
3. INSTALLING THE BATTERIES
Use only battery part number F741250003 with the unit. See Page 1 of this instruction manual.
A. Retaining brackets are provided. The batteries MUST be secured in the IIS-125. Do not leave the batteries
loose or unsecured within the unit.
B. Connect the batteries by plugging the connector into the receptacle on the PCB. If the batteries are not provided
with a connector, the PCB is equipped with Red and Black wires with ring terminals. Wire the Red wires to the
Positive terminals and the Black wires to the Negative terminals. Torque hardware to 33 in/lbs.
NOTE: Failure to connect or secure the batteries properly will result in equipment failure, an unsafe condition, and
will void the warranty.
NOTE: The emergency indicator lights will not illuminate at this time.
