ETC SC1008 Branch Circuit Emergency Lighting Transfer Switch

The SC1008 stands out as a pioneering branch circuit emergency lighting transfer switch (BCELTS) in its category. Its primary function is to seamlessly shift a single lighting circuit, capable of handling up to 20A, from one power source to another in the event of a power outage or other emergency scenarios. Engineered by ETC, it boasts a robust construction and incorporates fail-safe circuitry, holding a UL 1008 listing for North American emergency lighting applications where life safety is a paramount concern.

The SC1008 is designed to accommodate a regular power source, a normal sense, and an emergency feed for a single 20A circuit, compatible with both 120V and 277V systems, to supply power for normal and emergency loads. In cases of normal power loss, mechanically held relays take action by transferring both hot and neutral poles while effectively preventing unintentional connections between normal and emergency circuits. Additionally, it includes a fire alarm input and a signal disconnect relay, allowing for emergency control bypass of 0-10V or DALI fixtures.

ETC SC1008 Applications:

• Any emergency lighting application that requires UL1008 emergency transfer of a branch circuit

ETC SC1008 Features:

• UL1008 listed to transfer a single 20A circuit at 120V or 277V
• Field configurable fire alarm input can be normally open (N/O) or normally closed (N/C)
• Low voltage relay breaks a 0-10V or DALI loop sending the drivers to full in an emergency state
• Standard push button and laser test options
• Automatically transfers load from Normal power to Emergency power
• Automatically transfers back to Normal power when restored
