Energi Savr Node for 010 V-
Energi Savr Node with Softswitch
The Energi Savr Node (ESN) family is a group of modular
products for the control of lighting, receptacles, and other loads.
This document describes the following products:
Energi Savr Node for 010 V-
(models QSN-4T20-S, QSN-4T16-S-347)
Energi Savr Node with Softswitch
(models QSN-4S20-S, QSN-4S16-S-347)
Features
Rated to switch 20 A receptacles with any output.
Default configuration requires no commissioning.
Program using integral interface on the ESN unit.
Four occupancy sensor inputs for automated control of loads in
4 zones.
Four daylight sensor inputs automatically adjust light levels based
on the amount of natural light entering through the windows.
Four IR receiver inputs for personal control.
Four inputs for IEC PELV / NEC® Class 2 dry-contact switches.
Includes QS control link for seamless integration of loads, control
stations, and QS sensor modules.
Patented Softswitch circuit eliminates arcing at mechanical
contacts when loads are switched, prolonging relay life to an
average of 1,000,000 cycles at 16 A.
Contact Lutron for compatibility with a Quantum system.

Emergency Contact Closure Input
By default, contact closure input from Lutron Emergency
Lighting Interface (LUT-ELI-3PH), security, or fire
alarm systems turns all zones on to full output when
emergency state is detected.
Emergency contact closure input is normally closed (NC).
The ESN unit is shipped with a jumper pre-installed.
Response of each zone is configurable.
Attached devices, by default, will go to maximum output
and ignore control inputs.
No operations will be allowed until emergency signal is
cleared.

or solid-state output.
Input is miswire-protected up to 36 V-.
Emergency CCI cannot control other ESN units.
Functionality with GRAFIK Eye QS
• ESN unit follows GRAFIK Eye QS scene activations when
associated with the GRAFIK Eye QS.
• ESN unit responds to commands initiated by the GRAFIK
Eye QS astronomic time clock when associated with the
GRAFIK Eye QS.
• ESN unit operates in afterhours mode when associated
with a GRAFIK Eye QS that is in afterhours mode.
Functionality with QSE-IO
• ESN unit responds to scene commands initiated by the
QSE-IO if the QSE-IO DIP switches have been set to
either scene selection mode, zone toggle mode, partition
mode, or occupancy sensor mode.

operated accidentally. Examples of such equipment which must not be operated by these controls include (but are not limited to)
motorized gates, industrial doors, space heaters, etc. It is the installer’s responsibility to ensure that the equipment being controlled is
visible from every control location and that only suitable equipment is connected to these controls. Failure to do so could result in
serious injury or death.
