Introduction 3

Product Overview

The ETC Emergency Lighting Transfer System (ELTS2) is a UL 1008 Listed emergency load transfer

switch designed to switch lighting loads from one power source to another when there is a power

failure or other emergency situation present.

When a normal power failure is detected the ELTS2 automatically transfers the load (both hot and

neutral conductors) of the associated output to a separate emergency power source. When normal

power is restored the ELTS2 reconnects the load to normal power. The local control panel includes a

test key switch and LED indicators that clearly display the system status.

The ELTS2 is available in two panel sizes as standard:

• Small enclosure for two to twelve 20 A circuits of emergency AC lighting loads

• Large enclosure for two to twenty-four 20 A circuits of emergency AC lighting loads

The ELTS2 is available with optional discrete (Type D) emergency branch circuit feeds from an external

circuit breaker panel (by others) or emergency main feed (Type M) with built-in branch circuit

distribution.

Each transfer switch includes a pair of contactors, one for two 20 A circuits of

normal power and one for two 20 A circuits of emergency power. The two

contactors in the assembly are connected by a mechanical interlock in a manner

that ensures the circuits break from normal power before making the transfer

to emergency power and vice versa.

4ELTS2 Installation and User Operation Manual

Type D (Discrete Feed) Overview

With Type D ELTS2 units, each 20 A emergency circuit (hot and neutral conductors) are independently

fed from an adjacent emergency branch circuit breaker panel (by others). Normal 20 A circuits are fed

from an adjacent dimmer rack or branch circuit panel. Normal sense power wiring must be run from an

external 10–20 A circuit breaker.

Note:

The sense feed power consumption is essentially none.

Type M (Main Feed) Overview

With Type M ELTS2 units, emergency mains are connected to phase lugs within the unit. Mains power

is distributed through factory wiring to built-in branch circuit distribution and overcurrent protection.

Normal 20 A circuits are fed from an adjacent dimmer rack or branch circuit panel. Normal sense

power wiring must be run from an external 10–20 A circuit breaker.

6ELTS2 Installation and User Operation Manual

Standard Features

• The ELTS2 has a highly visible integrated local control station with a three-position test key switch

(Auto, Normal Power, and Emergency Power) for system test. The local station also includes a full

complement of system status indicators including:

• The ELTS2 enclosure provides ample space for contractor wiring.

- Standard NEMA 1 rated enclosure is 14 gauge welded steel enclosure with a hinged locking

door.

- Optional NEMA 4 rated enclosure is watertight and includes a hinged locking door.

• 240 and 277 VAC units are provided with integral transformers to step down normal phase A and

emergency phase A feeds to 120 V for the control electronics.

• ELTS2 units are provided with 20 A fuses for branch circuit protection.

• Dual inline pin (DIP) switches on the control electronics are provided for user-selectable timing

delays for power transfer between:

- the loss of normal power and the transfer to emergency power

- the restoration of normal power and the transfer from emergency power back to normal

power

• A normally closed dry contact closure is provided for Fire Alarm input.

• Up to five remote stations may be used per ELTS2 system. Remote stations include a key switch

for switching between normal and emergency states. Each station also includes two LEDs

illuminating the active ELTS2 state: Normal Mode or Emergency Mode.

• After normal power is restored the transfer switches return to the state previous to the power

loss.

• A transfer switch consists of a pair of contactors: One for normal inputs and one for emergency

inputs.

- Each contactor provides connection for line and neutral of two 20 A circuits on the input side.

- The two contactors in the assembly are connected by a mechanical interlock, which ensures

the circuits break from normal power before making the transfer to emergency power.

- Transfer Switches are rated for any mix of loads including tungsten, fluorescent, and discharge

lamps (in general terms, for resistive, capacitive, and inductive loads).

- Transfer Switches are rated for 6,000 cycles at full tungsten load.
