IMPORTANT:
Provide each unit with a single-phase AC un-switched power supply from a circuit used for normal lighting.
“UVOLT” product versions operate from 120 volts through 347 volts. PRODUCT DAMAGE WILL OCCUR IF THE RATED INPUT VOLTAGE IS EXCEEDED.
NOTE: The battery must be connected to the charger board prior to applying AC power to the unit. Battery damage may occur if the battery is connected longer than 24
hours without continuous AC power provided. See also “Important Battery Information”.
NOTE: The maximum mounting height of TCU 350L from ground is 17.1 feet, TCU 750L and TCU 750L HO from ground is 25.4 feet to meet the minimum illumination
requirements of NFPA 101 (current Life Safety Code).
NOTE: Do not connect battery or power unit until remote units (if applicable) are fully connected and wires are isolated from other potentials (i.e. remote wires shall be isolated from earth ground).
NOTE: Supports 4” Square, 4” Octagon or a single rectangular (4”x 2.125”) J-Box.

INSTALLATION

  1. Remove the front cover by removing two side screws, and slide cover up to remove (See Fig. A).LITHONIA LIGHTING TCU LED Steel Emergency Unit - 1 NOTE: for side mounting of lampheads see section Side Mounting Lampheads.
  2. To mount to a junction box, knock out the appropriate mounting pattern and the wire pass hole in the backplate to fit the J-box being used .
  3. To mount using conduit, mount the backplate to the wall in the desired location using the keyhole knockouts (See Fig. B). Attach a conduit hub to desired conduit mount holes on the backplate. An additional screw may be required at the lower end to pull the unit back into the wall as visible from the bottom of the unit.
  4. Use code-approved connectors to make the connection inside the unit. Connect the hot wire to the red lead. Connect neutral wire to the white lead. The ground wire (green lead) needs to be connected in accordance with the local codes. DO NOT energize the circuit at this time (See Wiring Diagram). For Units with Remote Lamp Wires: Connect remote wires to the remote output. The yellow wire is the positive remote wire and blue is the negative (See Wiring Diagram). If no remote lamps are connected, remote lamp leads (+ and – low voltage DC) should be capped and dressed in mounting plate to prevent shorting to circuit board, housing or each other.
  5. Connect the battery to the main board. Refer to the wiring diagram below.
  6. Replace the unit cover onto housing and torque screws to 10.6 in-lbs (1.2Nm) to ensure grounding of front cover.

    NOTE: This equipment is furnished with a sophisticated solid state transfer switch which will automatically disconnect the emergency lights from the battery if the battery has been discharged to the end of its useful output.

MAINTENANCE

CAUTION: Always turn OFF AC power to the equipment before servicing. Operator should disconnect battery if the lamps are on to remove power from lampheads before service lampheads. Servicing should be performed only by a qualified service technician. Only manufacturer SUPPLIED or APPROVED replacement parts must be used.
BATTERY: The battery supplied with this unit requires ZERO maintenance. However, it should be tested periodically and replace when it no longer operates the connected fixtures for complete duration of a monthly 30-second or annual 90-minute test.
NFPA 101 (current Life Safety Code) requires that all emergency lighting equipment be functionally tested every 30 days for a minimum of 30 seconds and tested annually for full 90-minute duration. Written records of the testing are to be kept for examination by the authority having jurisdiction.

TROUBLESHOOTING

  1. The emergency lights DO NOT operate:
    a) If the charge indicator light is OFF — Check that the circuit breaker and validate the AC supply voltage is present.
    b) If the charge indicator light is Red – Check that the battery is properly connected.

  2. If remote lamps are connected to the equipment and are not working:
    a) Turn OFF the AC supply, disconnect battery and disconnect the remote circuit wires from the equipment.
    b) Turn ON the AC supply, reconnect battery and depress the test switch.
    c) If the local lamps (mounted on the equipment itself) come ON, then check the remote circuit for short or overload condition and correct as required. Reconnect the circuit wires and restore AC power and battery connection.
    d) If the local lamps don’t turn ON after disconnecting the remote circuit wires, then replace battery.
    e) If the previous step does not resolve the problem, unit may need to be replaced.

  3. Emergency lights are dim-implies battery might not be fully charged. Allow battery to recharge for 24 hours and then retest.
