PRODUCT OVERVIEW
The
WSX
Family of wall switch occupancy sensors provides simple and cost effective
solutions for commercial and residential lighting control applications. All
WSX
Family sensors have a stylish low profile appearance, soft-click buttons, and provide
small motion detection up to 20 ft (6.10 m), making them perfect for private
offices, private rest rooms, closets, copy rooms, or any other small enclosed space.
Additionally, all
WSX
Family sensors have a patent-pending wiring method that
enables them to function either with or without a neutral connection.
WSX
units
come pre-configured for wiring without a neutral, however if connection to neutral
is required by code, contractors can convert the unit in seconds (see page 3).
All
WSX
Family sensors utilize 100% digital Passive Infrared (PIR) detection.
Dual Technology (
PDT
option) versions add Microphonics detection and are
recommended for offices and rooms with obstructions. Additional versions include
units with dual relays - perfect for bi-level applications, and units with an integrated
nightlight - perfect for restrooms and residential applications.
SENSOR OPERATION — WSX
sensors detect changes in the Passive Infrared (PIR)
energy given off by occupants as they move within the field-of-view. In an Auto-On
sensor, once occupancy is detected, an internal relay switches on the connected
lighting load. In a Vacancy (Manual On) sensor, the unit’s push button must first be
pressed to initiate the lights on. In a dual relay sensor, once occupancy is detected
the unit will automatically close Pole 1’s relay while still requiring Pole 2’s push-
button be pressed in order to close Pole 2’s relay. All modes are user adjustable (see
On Modes section).
After the lights are turned on, an internal timer keeps them on during brief periods
of inactivity. Once the time delay has expired, lights are turned off automatically.
The default time delay is 10 minutes - chosen in order to maximize energy savings
while preventing false-offs. This timer is programmable from 30 seconds to 30
minutes, and is reset every time occupancy is re-detected. Patented LampMaximzer
technology is also present in these sensors, providing an additional minimum on
time (disabled by default) to be utilized if desired.
WSX
sensors with Passive Dual Technology (
PDT
option) first see motion using
Passive Infrared (PIR) and then engage Microphonics to listen for sounds that also
indicate continued occupancy. This patented technology dynamically adapts a
sensor to its environment by filtering out constant background noise and detecting
only noises typical of human activity.
KEY OPTIONS
NIGHT LIGHT (NL)
Ideal for bathrooms (hotel / hospital) or residential applications
• Ultra low power White LED night light (24/7 operation)
• Capable of powering over Ground (no Neutral required)
• Manual On / Auto Off operation of lights (default)
• Available with Single or Dual Relays
DUAL RELAY (2P)
Ideal for bi-level switched rooms or restroom with light & fan
• Includes two isolated relays, Pole 1 defaulted to Auto On, Pole 2 to Vacancy
• Enables separate time delay per pole - programmed via each pole’s push-button
• UL listed to switch different loads per pole - e.g. 277 VAC lights on Pole 1 and 120
VAC fan on Pole 2
LOW TEMPERATURE / HIGH HUMIDITY (LT)
Required for cold / humid areas
• Device electronics are coated for corrosion resistance
• Operates down to -40º F/C (-4º F / 20º C for PDT)
WSX
FAMILY
WALL SWITCH SENSOR w/
CONVERTIBLE NEUTRAL / NO NEUTRAL WIRING,
PASSIVE INFRARED (PIR) or DUAL TECH (PDT)
• 100% digital PIR detection - excellent RF immunity
• Ruggedized assembly, vandal resistant lens standard
• Small motion detection to 20 ft
• Dual Technology (PDT) utilizes PIR / Microphonics
detection (patented)
