DESCRIPTION AND OPERATION
The ELCU-100 Emergency Lighting Control Unit allows lighting control devices for normal lighting to also control emergency lighting
installed within the area. The ELCU is designed for lighting control in areas where emergency lighting fixtures are connected on
dedicated emergency lighting circuits that are typically
ON
24 hours per day. The ELCU allows
ON/OFF
control of the emergency
lighting along with the normal room lighting to save energy.
The intended operation of the ELCU is to guarantee that the emergency lighting is
ON
whenever normal power to the controlled circuit
is interrupted. While normal power is present, the ELCU allows control of the emergency lighting by a device such as an occupancy
sensor, a relay, a dimmer, or a wall switch.
Important Safeguards
When using electrical equipment always follow basic safety precautions:
• READ AND FOLLOW ALL SAFETY INSTRUCTIONS–SAVE THESE INSTRUCTIONS
• Mount only in an industrial control panel with a DIN rail mounting system.
• Do not use near gas or electric heaters.
• Equipment should be mounted in locations and at heights where it will not readily be subjected to tampering by unauthorized personnel.
• Use of accessory equipment not recommended by the manufacturer may cause an unsafe condition.
• Do not use this equipment for other than intended use.

Wiring Notes
1. You can connect as many NC contacts (including LMTS-100) in series on the jumper loop wire as you want to a single ELCU. You
cannot connect the NC devices in any other manner.
2. At no time can more than 5 ELCU devices can be controlled together by commoning their Test Loop wires to a Normally Closed
Test Switch (LMTS) and/or other NC contact closure.
3. If connecting ELCUs together via their test loop wires, you must maintain the polarity of their wires.
