Coverage Patterns - LEGRAND Wattstopper PW-203 Installation Instructions Manual

PIR Sensitivity Adjustment
The PW sensor constantly monitors the controlled environment and automatically adjusts the PIR to avoid common ambient conditions
that can cause false detections, while providing maximum coverage.

Alerts
The PW can provide audible and/or visible alerts as a warning before the load turns OFF.

Turning ON the Load
The relays are programmed independently for either Auto ON or Manual ON. In either mode, the load can be turned ON or OFF using
the ON/OFF button. In either mode, the load can be turned ON or OFF using the ON/OFF button.
Auto ON
(DIP# 8 OFF for Relay 1)
(DIP #9** OFF for Relay 2)
Manual ON
(DIP #8 ON for Relay 1)
(DIP #9** ON for Relay 2)
** Switch 9 default is ON for Manual ON functionality of Relay 2 to comply with California Energy Commission Title 24 bi-level switching
requirements.

Coverage testing has been performed according to the NEMA WD 7
guideline. For best performance, use in spaces not larger than
15' x 12'.
PIR Sensor
The sensor has a two-tiered, multi-cell viewing Fresnel lens with
180 degree field of view. The red LED on the sensor flashes when
the PIR detects motion.
Masking the lens
Opaque adhesive tape is supplied so that sections of the PIR
sensor's view can be masked. This allows you to eliminate coverage
in unwanted areas. Since masking removes bands of coverage,
remember to take this into account when troubleshooting coverage
problems.

Default setting. Suitable for most applications.
Reduces sensitivity by approximately 50%. Useful in cases where the PIR is detecting movement
outside of the desired area (also consider masking the lens) and where heat sources cause unnecessary
activation.
When only one minute is left in the time delay, the load connected to the relay turns OFF for one second.
This provides a one minute warning before the load(s) are turned OFF by the sensor.
No visible warnings provided.
Unit will beep at one minute, at 30 seconds and at 10 seconds before turning OFF load. When Walk-
Through is active, the unit beeps three times at 10 seconds before the load goes OFF.
*If Visible Alert is also ON, the one-minute time-out warning beep is replaced by the visible alert.
No audible warnings provided.
With an ON Mode DIP Switch in the OFF position, the load turns ON and OFF automatically based on
occupancy. If the load is turned OFF manually, Presentation Mode operation applies. This prevents the
load from turning ON automatically after it was deliberately turned OFF. Pressing the button to turn lights
ON returns the sensor to Auto ON mode.
With an ON Mode DIP Switch in the ON position, the occupant must press the ON/OFF button to turn
ON the load. The sensor keeps the load ON until no motion is detected for the selected time delay. There
is a 30 second re-retrigger delay. If occupancy is detected during the delay, the sensor turns the load
back ON. After the re-trigger delay elapses the ON/OFF button must be pressed to turn ON the load.
