Instructions
Overview
SENSORWORX power pack controllers transform incoming line voltage power to Class 2 low voltage as needed by sensors or other control devices. Additionally, they switch on/off power to the connected lighting load as directed by the sensors and controls. SENSORWORX power packs utilize a powerful microprocessor to optimize its switching timing in order to ensure long relay life even when controlling high-inrush LEDs and ballast loads. As with all SENSORWORX products, these power packs are easy to install and incorporate features which reduce contractor labor time. An elongated chase nipple with snaps for quick installation and an optional snap-on low voltage wire chamber make for a hassle free contractor experience. All SENSORWORX products are proudly made in the USA.
Basic Operation
An input signal indicating occupancy from one or more connected sensors will signal the pack’s integrated relay to close. Once closed, line voltage will flow through the relay and turn on the connected lighting load. When the input signal indicates the occupied period has ended, the relay will open and lighting will switch off. This pack is also available with an auxiliary switch input to enable manual on, hold on, and hold off configurations.

Power Packs with Secondary Relay Pack
Power Pack Connected to Switch – Momentary Switch (Requires –AX Option)
- Some energy codes require Manual On (also called Vacancy) operation where an occupant is required to initially switch on lighting. The sensor then ensures lights are turned off once the space is unoccupied
- Interfacing momentary switches such as the SWX-801-xx or SWX-803-xx are recommended, however maintained switches can also be utilized
- For momentary switches, the power pack will react on the leading edge of a pulse on the brown input wire
- For maintained switches, any change of state on the brown wire that lasts longer than 0.5 seconds will be read by the power pack as one action
- If no sensor is present, tie power pack low voltage white wire to low voltage red wire

Power Pack with Switch Signal from External System
-
Typical for Hold On and Hold Off applications
-
BROWN switch input can be activated by external signals +5VDC or higher (i.e. logic high)
-
For hold on and hold off applications, switch input can also be configured to activate on logic low
-
If no sensor is present, tie power pack low voltage white wire to low voltage red wire
Multi-Way Switching (Requires -AX Option)
- Switching a powerpack from multiple locations (i.e., 3-way, 4-way switching) can be achieved using multiple SENSORWORX model# SWX-801-xx switches or a combination of one model# SWX-803-xx dimmer and one or more model# SWX-801-xx switches.
- Note that only one dimmer should be used per multi-way application.
- If no sensor is present, tie power pack low voltage white wire to low voltage red wire
