INSTALLATION INSTRUCTIONS
CAUTION: Before installing, make certain the A.C. power is off.
NOTE: The batteries are shipped separately. Place them in a location away from the work area to avoid damage until
they are to be installed.
1. Mounting the IIS-125 with Dimming Relay
RECESSED TEE BAR CEILING MOUNT (IIS-125-CG-DR)
ATTENTION: The IIS-125 with Dimming Relay is not for use in air supply/air return ceilings.
1) Remove the side cover from the IIS-125-CG-DR.
2) Remove the ceiling tile in the desired installation location.
3) Extend the unswitched, properly-rated voltage AC supply and remote fixture wires to the installation area.
4) Place the IIS-125-CG-DR across the 2 ′ T-bars of the ceiling grid. Support the unit with wires attached to the
building steel framing. Holes are provided at the top of the IIS-125-CG-DR for support wire connection. NOTE: Do
not rely on the inverted T-bar structure to support the unit.
5) Connect the conduit containing the AC supply and remote fixture leads to the IIS-125-CG-DR. Use the provided
knock-outs on the IIS-125-CG-DR for connecting the incoming wires.
6) Remove the battery retaining bracket and install the batteries at this time, but do not connect the battery leads
until other wiring is completed. Reinstall the battery bracket. NOTE: The batteries MUST be secured in the
IIS-125-CG-DR. Do not leave the batteries loose or unsecured within the unit.
7) Use the wiring instructions on page 3 to complete connections within the IIS-125-CG-DR.
8) After installation is complete, replace properly-sized tile into the ceiling grid. The tile should rest on the flange of
the IIS-125-CG-DR.
SURFACE WALL MOUNT (IIS-125-SM-DR)
1) Remove the front cover of the IIS-125-SM-DR by removing the two screws at the top of the cover.
2) Extend the unswitched, properly-rated voltage AC supply and remote fixture wires to the installation area. If a
recessed junction box is to be mounted in the wall behind the unit, make sure that the unswitched AC supply and
any remote fixture leads have been extended to the junction box prior to mounting the
IIS-125-SM-DR and that
there is at least 12 ″ of exposed leads for wiring in the unit.
3) Knock out the (2) keyhole slots at the rear of the unit and mount the IIS-125-SM-DR securely to the wall. IIS-125-
SM-DR must be mounted securely. The keyhole slots are spaced to allow mounting to the wall’s unistrut or studs.
4) Connect the conduit containing the AC supply and remote fixture leads to the IIS-125-SM-DR. Use the provided
knock-outs on the IIS-125-SM-DR for connecting the incoming wires.
5) Remove the battery retaining bracket and install the batteries at this time, but do not connect the battery leads
until other wiring is completed. Reinstall the bracket
NOTE: The batteries MUST be secured in the IIS-125-SM-DR.
Do not leave the batteries loose or unsecured within the unit.
6) Use the wiring instructions on page 3 to complete connections within the IIS-125-SM-DR.
2. WIRING
1. CONNECTING THE NORMAL AC INPUT (DIAGRAMS 1 AND 2)
A.
For 120V supply, connect the AC line wire to the BLACK lead labeled INPUT. For 277V supply, connect the AC
line wire to the ORANGE lead labeled INPUT. CAUTION: Cap the unused BLACK or ORANGE input wire.
Failure to do so may result in equipment failure and void the warranty.
B. Connect the Neutral wire to the WHITE lead labeled INPUT. When making connections to the IIS-125, DO NOT
connect the Input Neutral (WHITE) to the Output Neutral (GRAY).
C. Connect the ground wire in accordance with local and national codes. A GREEN wire is provided for this purpose.
Note: If the emergency fixtures are to be NORMALLY ON or SWITCHED, you may have to connect flying lead wires
to these wires as well. Refer to Diagrams 1 and 2 and STEP 2 below.
DO NOT ENERGIZE THE CIRCUIT AT THIS TIME.
