COVERAGE PATTERNS
Coverage testing has been
performed according to the
NEMA WD 7 guideline. For best
performance, use in spaces not
larger than 18’ x 15’.
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.
Ultrasonic Sensor
The sensor has two ultrasonic transceivers operating at 40kHz. Detection
sensitivity can be adjusted using the trimpot under the ON/OFF buttons.
Service Mode
The Service Mode allows the DW to operate as a toggle switch. Service Mode
turns off all the sensor features and only allows load control through the
button(s). While in Service mode the time delay, detection, and light level
settings are ignored and Ultrasonic transmisions are turned off. To activate the
Service Mode, turn the Ultrasonic trimpot fully clockwise to MIN. The Red LED
turns on and stays on until the trimpot is returned to a normal setting.
