Code Refresher

NFPA 101 - 7.9.2.3

- Failure of a public utility or other outside electrical power supply

- Opening of a circuit breaker or fuse

The emergency lighting system shall be arranged to provide the required illumination automatically in the event of any interruption of normal lighting due to any of the following:

- Manual act(s), including accidental opening of a switch controlling normal lighting facilities

Localized Failure

The ELCDs go as close to the lights as possible

Some Things to Keep In Mind

The Inverter may not be in "emergency mode" at the same time as the downstream lights

- They should be observing the power feed that goes to the lights

- They should not be observing the power feed going to the inverter

Automatic Load Control Relay

ISOLITE

TRANSFERRING POWER, THE ELCDs

Chalk Talk

A device used to set normally dimmed or normally-off switched emergency lighting equipment to full power illumination levels in the event of a loss of the normal supply by bypassing the dimming/switching controls, and to return the emergency lighting equipment to normal status when the device senses the normal supply has been restored.

Definition

ALCR Devices are used to override dimming/switching controls.  They require a Normally On power source.

In Plain English

II. ELCDS IN GENERAL

Branch Circuit Emergency Lighting Transfer Switch

ISOLITE

TRANSFERRING POWER, THE ELCDs

Chalk Talk

A device connected on the load side of a branch-circuit over-current protective device that transfers only emergency lighting loads from the normal supply to an emergency supply.

Definition

BCELTS devices change the power source that supplies power to a fixture. They convert Normally Off sources into Normally On sources.
