PRODUCT OVERVIEW

The WSD is a stylish, easy to install, and simple to use Wall Switch Decorator style

Passive Infrared (PIR) sensor. It is ideal for private oces, copy rooms, closets, or

any small enclosed space without obstructions. A user programmable time delay

ensures that once the room is vacated the sensor will time out and turn o the lights.

Additionally, the WSD sensor has several On Modes and Switch Modes that can be

programmed using the front push-button. For rooms with obstructions, the Dual

Technology WSD PDT Series sensor is recommended. Additionally, all WSD Family

sensors have a patent-pending wiring method that enables them to function either

with or without a neutral connection. WSD units come pre-congured 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 WSD Family sensors utilize 100% digital Passive Infrared (PIR) detection.

Dual Technology (PDT option) versions add Microphonics detection and are

recommended for oces and rooms with obstructions. Additional versions include

units with dual relays - perfect for bi-level applications, or bathrooms with a light

and a fan.

SENSOR OPERATION  WSD sensors detect changes in the Passive Infrared (PIR)

energy given o by occupants as they move within the eld-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 rst 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 setting).

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 o automatically.

The default time delay is 10 minutes - chosen in order to maximize energy savings

while preventing false-os. 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.

WSD sensors with Passive Dual Technology (PDT option) rst 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 ltering out constant background noise and detecting

only noises typical of human activity.

KEY OPTIONS

VACANCY OPERATION (SA and VA)

Increased energy savings and required by many codes

• The unit’s push button must rst be pressed to initiate the lights on

• SA version can be reprogrammed to Auto-On operation

• VA version operates in Manual On mode only

DUAL RELAY (2P, 2P-SA, and 2P-VA)

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 dierent loads per pole - e.g. 277 VAC lights on Pole 1 and 120

VAC fan on Pole 2

• 2P-SA and 2P-VA versions are factory set with both poles set to manual on

LOW TEMPERATURE / HIGH HUMIDITY (LT)

Required for cold or humid areas

• Device electronics are coated for corrosion resistance

• Operates down to -40º F/C (-4º F / 20º C for PDT)

WSD Family OPERATIONAL SETTINGS __________________________________________________________________________________________________ Predictive Mode (setting 3) determines if a user has left the room after the lights are switched off. It does this by monitoring the space for a period after the button is pressed (Predictive Grace Time), following a delay to allow exiting the room (Predictive Exit Time).

WSD Family COVERAGE PATTERN TOP VIEW • Small motion (e.g., hand movements) detection up to 20 ft (6.10 m), ~625 ft2 • Large motion (e.g., walking) detection greater than 36 ft (10.97 m), ~2025 ft2 • Wall-to-Wall coverage • Passive Dual Technology (Microphonics) provides overlapping detection of human activity over the complete PIR coverage area. Advanced filtering is SIDE VIEW utilized to prevent non-occupant noises from 1.2 m 4 ft keeping the lights on.
