Energi Savr Node

Product Overview

An Energi Savr Node (ESN) system consists of an ESN unit, output loads, sensors, keypads, and QS interface devices. The diagram on page 1 shows a
TM
typical system topology.
• All lighting loads and ESN units are powered by line voltage.
• The ESN unit is limited to:
– 4 Lutron daylight sensors (models: EC-DIR)
®
– 4 Lutron occupancy sensors (models: Lutron
®
– 4 Lutron keypads or infrared (IR) receivers (models: PX-2B, PX-2BRL, PX-3B, PX-3BRL, EC-DIR, EC-IR, CC-4BRL)
®
– 4 IEC PELV / NEC Class 2 dry-contact switch inputs
®
– 1 contact closure input
– 1 emergency contact closure input (defaults to Emergency Mode in the absence of a contact closure across the input)
• The ESN unit is limited to:
– 16 total wired or wireless occupancy sensors across all 4 zone outputs
– 1 wired or wireless daylight sensor per zone
• The QS Link can have up to 100 zones and 100 devices.
• The ESN unit counts as 1 device and 4 zones on the QS link.
• In a system with multiple ESN units on a QS link, a maximum of 100 daylight sensors, 100 occupancy sensors, 100 IR receivers, and 100 Pico
wireless controllers are permitted.
• The ESN unit supplies up to 14 Power Draw Units (PDUs) for powering accessory QS devices. Refer to accessory device documentation for power draw
information.
Refer to the following step-by-step guide for proper ESN unit installation.
