Page 7: Product Overview
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. -
Page 8: Type D (Discrete Feed) Overview
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. -
Page 9: Type M (Main Feed) Overview
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. -
Page 10: Standard Features
• 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. -

When a phase of the normal power feed connected to the ELTS2 falls below the specified voltage for that phase for the preset amount of time. During a power fail, the ELTS2 will transfer all connected lighting loads to the alternate power source when it is available and stable. -
Page 12: Installation
Installation Requirements Locate the ELTS2 unit in a location where it will not be subject to tampering or vandalism. If possible, install the ELTS2 where it is most secure from damage by fire, flood, or other incident likely to require its use. -
Page 13: Electrical Requirements
Mixing voltages within the ELTS2 may cause system failure. The ELTS2 is available in three base voltages including 120 VAC, 240 VAC, or 277 VAC. 120 VAC / 60 Hz units may be any form of 120 VAC power including: •... -

Suivez les procédures de Consignation/Déconsignation appropriées prescrites par la norme NFPA 70E. Requirements for installation vary depending on the type of ELTS2 in your installation (either Type D - Discrete Feed or Type M - Main Feed). See page 12... - Page 21 Rough-In Conduit and Cable for Type D (Discrete Feed) Unit The discrete feed ELTS2 is designed for emergency systems where 20 A emergency branch circuits (hot and neutral conductors only) are fed to the discrete emergency branch circuit terminal strip. Normal 20 A circuits (hot and neutral conductors only) typically fed from an adjacent dimmer rack or circuit breaker panel are wired directly to the normal input side of transfer switch assembly.
- Page 22 Rough-In Conduit and Cable for Type M (Main Feed) Unit The main feed ELTS2 is designed for systems where emergency mains are connected to phase lugs within the ELTS2 unit. Mains power is distributed to the transfer switches, and then to fuses that provide branch circuit protection.
