SC1008 Branch Circuit Emergency Lighting Transfer Switch
Overview
The SC1008 Branch Circuit Emergency Lighting Transfer Switch (BCELTS) transfers a single lighting
circuit from its normal power source to an emergency power source in the event of the loss of normal
power or an external trigger (e.g., fire alarm).
The SC1008 BCELTS includes the following features and functions:
a front panel accessible push–and–hold Test Switch
•
a front panel accessible Laser Test, enabling remote testing with the use of a laser pointer (or
•
similar)
front panel status indicators for Normal Power (green) and Emergency Power (red)
•
a fire alarm dry contact input, which can be set for normally open or normally closed operation
•
an auxiliary relay for 0–10V or Digital Addressable Lighting Interface (DALI) control signals
•

Page 2: Installation Requirements
ETC Installation Guide SC1008 BCELTS Installation Requirements Install the SC1008 in a location that is accessible by qualified personnel for testing of the transfer function using either a laser pointer (or similar) or the onboard test switch. The SC1008 installs to a flat surface, has four conduit entry locations, and includes a universal mounting plate with four mounting holes. -

ETC Installation Guide SC1008 BCELTS Earth Ground Wire and Terminal Specifications on page 4 for specification of wire, strip length, and terminal torque ratings, and then prepare and terminate your earth ground wire to the lug provided in the enclosure. - Page 6 ETC Installation Guide SC1008 BCELTS Dimmed or Switched Load The SC1008 has the ability to separate the sensing of normal power from the load itself; this allows you to have a light switch or dimmer controlling the load when normal power is available, but to have the load transfer to emergency power in the event of normal power loss.
- Page 7 SC1008 BCELTS ETC Control Panel The SC1008 can also handle loads from ETC dimming and relay panels. In some cases, unlike the example on the previous page, the sense hot line cannot be separated prior to the dimmer or relay.
- Page 8 All low–voltage Class 2 wiring must be separated from all Class 1 wiring. Follow local codes and installation restrictions. ETC recommends limiting the distance run for the 0 – 10 V control wiring from the controller to the last ballast (driver) to 300 ft (90 m), based on 18 AWG wire.

Page 10: Test Button
In–line fuses are present for the normal power input and the emergency power input. Replace fuses only with Class G SLC 30 A fuses (order ETC part number F392). 1. Disconnect both power supply sources and lock/tag out appropriately. -
