Wall Switch Sensors

SWX-100 SERIES

Overview

The SENSORWORX family of wall switch occupancy sensors provides a simple yet cost-effective lighting control solution for many retrofit applications. Designed with contractors in mind, the SENSORWORX wall switch sensor is significantly shallower than typical sensors, resulting in less crowded wall boxes. Additionally, versatile wiring enables usage with or without a neutral and allows reversal of line and load connections. SENSORWORX products utilize the latest passive infrared technology and digital signal processing techniques to provide unmatched motion detection performance. These units are also available with an integrated microphone to provide overlapping passive acoustic occupancy detection for rooms with obstructions or where occupant motion is limited.

Basic Operations

Sensors detect movement in the infrared energy that radiates from occupants as they move within the devices field-of-view. Once occupancy is identified, the sensor’s internal relay switches power on to the connected lighting. Units can also be configured to operate in Vacancy Mode (e.g., require lights be manually switched on). Once lights are on and if equipped with passive dual technology (PIR/Acoustic), the unit’s microphone is enabled to further enhance detection. An internal timer is set to keep lights on during brief periods of inactivity, and is reset every time occupancy is signaled by either the passive infrared or acoustic detection technologies. Ambient daylight detection can also be enabled in equipped units so that lights are held off in rooms with sufficient light contribution from windows or skylights.

Applications

A wall switch sensor is typically used to retrofit an existing wall switch in a small room or enclosed space. A Passive Infrared (PIR) only sensor is sufficient for spaces where line of site is maintained and occupants are periodically moving (e.g., copy rooms, storage rooms). Dual technology sensors are necessary where occupants may be partially blocked from the sensor’s direct view or where they may be stationary (e.g., private offices or restrooms with stalls).

Multi-Gang Switch Replacement

Many residential and commercial building spaces contain multi-gang switch locations (i.e. locations on the wall that have more than one single-gang switch devices in the same wall box). The SENSORWORX solution for these applications utilizes a wall switch occupancy sensor and one or more added “sidecar” wall switches that receives necessary occupancy information from the adjacent sensor. Each unit can be configured separately for Auto On or Manual On (Vacancy) operation and time delay. Most conveniently, this solution enables adding a standard multi-gang decorator switch plate in order to provide an aesthetically pleasing appearance without any awkward and conspicuous blank wall plate sections. Additional sidecar switches can also be added to create 3-pole (or greater) solutions.

INBOARD / OUTBOARD SWITCH REPLACEMENT
Many older buildings have fluorescent light fixtures wired for inboard/outboard control by a pair of wall switches. Retrofitting these wall switches with code-compliant controls is attractively done with a SENSORWORX 2-pole solution (model: #SWX-102 or SWX-122). These two unit kits contain an Auto On occupancy sensor and a Manual On sidecar switch that work together to meet the required partial on energy code requirements.

BATHROOM LIGHTS & FAN
Bathrooms often have separate switches for lights and ventilation fans. In some cases two switches for lights (e.g. vanity and shower) and the fan are all contained in the same 3-gang wall box along the entry wall. Retrofitting these switches with a SENSORWORX wall switch sensor and two sidecar switches is an attractive and energy efficient solution for providing occupancy control of all three loads.

  • Unit returns to full sensitivity after initial turn-on

LED Functionality

Operational Modes

SENSORWORX wall switch sensors are intelligent devices that provide both excellent energy savings and enhanced user convenience. Users can choose from several pre-programmed operational modes that best fit their preferences and applicable energy codes. Note that both the master wall switch sensor unit and sidecar switch unit in 2-Pole solution (SWX-102, SWX-122)  have independent operational modes.

1 Vacancy Mode
Manual On / Automatic Off operation. Lights can also be switched off manually. This mode provides increased energy savings but requires the user to initially turn on the lights. Models SWX-103, SWX-104, SWX-123, and SWX-124 default to Vacancy modes. Sidecar switch units (SWX-831-SC) in 2-Pole kits also default to Vacancy mode.

2 Automatic On Mode
Automatic On and Automatic Off operation. If lights are switched off manually, the Automatic On functionality is temporarily disabled until the space becomes unoccupied and the sensor’s time delay expires. This mode is the default operation of SWX-101, SWX-111, SWX-121, and SWX-131 models and is perfect when occupants turn off the lights but remain in the room (e.g., for a presentation).

3 Automatic On w/ Exit Time Mode
Automatic On and Automatic Off operation. If lights are switched off manually, the Automatic On functionality is disabled for a fixed 30 seconds to allow a person time to leave the room.

4 Override Off Mode
Automatic On and Automatic Off operation until lights are switched off manually, at which point Automatic On functionality is disabled until the switch is pressed again.

5 Disabled Switch Mode
Automatic On and Automatic Off operation only. Switch functionality to manually turn on/off lights is disabled.
