Description:
The PS-HC24-R is a low voltage High Denition Infrared (HDIR)
Presence Sensor designed to work with any PerfectSense power
pack, to automatically control lighting in standard and cold
weather applications. This sensor utilizes an industry leading
8-Element Infrared detector for superior minor motion detec-
tion. The sensor operates in climates down to -40° Fahrenheit or
Celsius. Dual Form C Relays are present on the sensor to allow for
integration to NexLight’s 2-wire system and HVAC/BMS Systems.
The sensor turns the lights on and keeps them on while occu-
pancy is detected and will turn the lights o after the delayed-
OFF time has expired.
Operation of Sensor:
Motion detection by the HDIR sensor will turn ON the lights as
well as keep them ON. When motion is not detected, the lights
will turn OFF after the delayed-OFF time.
Walk-Through Mode:
The walk-through feature is useful when a room is momentarily
occupied, such as a storage room. When a person enters the
room, the lights will turn on and stay on for 2.5 minutes. After 2.5
minutes the lights will shut o.
Scenario A: If motion is detected within 10 seconds of the lights
shutting o, the sensor will proceed to standard operation (5s to
30m). After the lights shut o, the sensor will revert back to
walk-through mode.
Scenario B: If no motion is detected within 10 seconds of the
lights shutting o, the sensor will stay in walk through mode and
the next time it sees detection the lights will turn on for 2.5
minutes.
Daylight Sensor:
To enable daylight sensor operation, set Dip Switch 1 in Bank B
to OFF. This puts the sensor in a stand-by mode when the natural
light level exceeds the selected Foot Candles (FC) level inhibiting
the lights from turning ON.
LED Operation:
The Sensor has two LED indicators that, when enabled, will ash
when motion is detected. These LEDs are Enabled/Disabled via
DIP switch 2 in Bank B. When enabled, a red ash indicates that
motion has been detected by Infrared Technology.
Features:
• 1000 sq ft Range
• 300 sq ft minor motion detection range
• Patented HDIR 8-element Sensor
• 864 Optical Field-of View Pattern
• 360° Coverage Pattern

Each time motion is detected, the lights remain
activated for a pre-set time, which is set by the
O-time adjustment. The fully counter-clockwise
setting (30seconds) can be used for testing. If
motion is detected during the ON time, the timer
resets and lights will remain on until the full
PIR sensitivity can be dialed up or down to meet
the exact needs of anyspace. This adjustment is
helpful to ensure detection in all areas during a
walk test.

DETECTION AND ACTIVATION:
When a person enters a room, the sensor detects major body motion
and turns the light on. The light is kept on even as smaller body
movement is detected. This sensor’s detection sequence logic (DSL)
minimizes false triggering by continuously analyzes the motion
detection signal and adjusts internal operation to maximize the
and electrical noise.

DESCRIPTION:
Sensor designed to work with any PerfectSense power pack, to auto-
matically control lighting in standard and cold weather applications.
This sensor utilizes an industry leading 8-Element Infrared detector for
superior minor motion detection. The sensor operates in climates down
to -40° Fahrenheit or Celsius. Dual Form C Relays are present on the
sensor to allow for integration to NexLight’s 2-wire system and
HVAC/BMS Systems. The sensor turns the lights on and keeps them on
delayed-OFF time has expired.
There is a daylight sensor built into the sensor to allow for ambient light
override functionality. If the ambient light level in the room is at a
this setting is used, the controlled lighting load will only turn on if the
ambient light present is less than the desired setting.
INSTALLATION:
See the back of this installation manual for installation instructions. The
sensor is fully operational after 30 seconds of powering up the device.
OPERATION OF SENSOR
Delayed-OFF Time: The sensor is designed to turn the lights OFF if no
black twist knob designated for timer inside the control console. Depen-
dent upon environmental conditions and occupancy patterns, the
adapting patterns will modify the delayed-OFF time to match the
parameters of each installation.
Walk-Through Mode: The walk-through feature is useful when a room is
momentarily occupied, such as a storage room. When a person enters
the room, the lights will turn on and stay on for 2.5 minutes. After 2.5
Scenario A: If motion is detected within 10 seconds of the lights shutting
Scenario B: If no motion is detected within 10 seconds of the lights
it sees detection the lights will turn on for 2.5 minutes.
Daylight Sensor: To enable daylight sensor operation, set Dip Switch 1
in Bank B to OFF. This puts the sensor in a stand-by mode when the
natural light level exceeds the selected Foot Candles (FC) level inhibiting
the lights from turning ON.
LED Operation: The Sensor has two LED indicators that, when enabled,
has been detected by Infrared Technology.
Infrared Adjustment- For maximum range, set fully clockwise (CW). If
reduced range is required, then turn counterclockwise (CCW) and test
Delayed-OFF Time Adjustment: Each time motion is detected, the load
remains activated for a pre-set time, which is set by the Delayed-OFF
Time Adjustment, The fully CCW setting (30 seconds) can be used for
testing. The fully clockwise setting is 30 Minutes. If motion is detected
during the ON time, then the load remains activated until the full ON
time has passed since the latest motion detection.
Daylight Sensor Adjustment: This level needs to be set in a room where
natural light is at the desired level for the lighting load to not be turned
on. The sensor will still see motion (indicated by the red LEDS)
Test Mode: This mode is used to set the Delayed-OFF Time to 5 seconds for
while in test mode.
1. Ensure Power is On
2. Remove the cover from the Operation Control Console
defaulted to the OFF position.
4. To enter Test Mode, move the switch from OFF to ON and then back to
OFF. If B3 is already in the ON position, test mode can be entered by just
moving it back to the OFF position.
Notes for Test Mode:
1. The Delayed-OFF Time will remain in the 5 second test mode for 15
minutes. It will then automatically reset to the Delayed -OFF Time setting
as dened by the black adjustment knob in the control console and exit
test mode.

Sensor Technology Comparison
HDIR technology signicantly surpasses known boundaries of IR sensor technology. Extending the capability of IR to new
levels of accuracy through a combination of patented sensor hardware and logic algorithms. The power behind this innova-
tion originates from a proprietary 8-element pyros infrared element that eclipses current competitive sensor logic technolo-
gies. Eight-Hundred and Sixty-Four (864) optical view patterns are achieved, delivering unmatched sensitivity for minor
motion events like hand and nger movements. Paired with ultrasonic technology for a complete solution designed to meet
the demands of Title 24 and ASHRAE 90.1.
