Sensor Technology
PIR (Passive Infrared)
Passive Infrared (PIR) technology is the industry standard for
detecting motion in a monitored space by detecting the difference
in heat emitted from the human body and from the background
space. PIR works well in smaller spaces with a high level of
occupant movement. Relying on PIR for motion detection requires
clean line of sight to the occupant. Due to the limitations of PIR
and the need to have clear line of sight with the occupant, Dual
Technology (DT) occupancy sensors have been developed using
a number of secondary detection technologies.
Ultrasonic
Ultrasonic technology measures the difference in frequency
between the emitted and reflected waves. Ultrasonic technology
does not require a direct line of sight to detect motion; however,
it is sensitive to disruptions in airflow caused by HVAC systems,
which can lead to false triggers.
Microphonic
Microphonic technology is considered an improvement over
ultrasonic technology and a reliable, robust secondary detection
technology. Microphonic technology listens for sound rather
than “looking” for movement thus not being confused by air
movement or movement of plants and window blinds. This
passive technology uses less power than ultrasonic sensors
because it waits to hear sounds rather than actively sending out
and receiving ultrasonic waves.
ADI-Voice® (Accurate Detection Intelligence)
ADI-Voice is our proprietary microphonic technology that utilizes
advanced digital signal processing for accurate detection of
human vowel sounds from background noise. This minimizes
the common causes of false triggers caused by non-human
background noise such as HVAC systems, traffic, music, and
vibrations.

Diversa Occupancy & Vacancy Sensors
When interior spaces require sensor control for lights and loads, look no further that Diversa commercial grade occupancy and vacancy
sensors. Diversa sensors can be used in a variety of locations to meet projects specifications while enabling your site to meet California
Title 24, NYLL48 and AHSRAE compliance.
Diversa Dual Technology sensor are available in recessed ceiling, wall switch and corner mount designs and all use PIR and our ADI-Voice
to maximize sensing effectiveness while minimizing false triggers from common interference items such as HVAC systems, music, vibrations,
knocking and traffic. These sensors meet the needs in high spec projects by providing a wide variety of configuration features and options.
Configurations can be done with on-board switches and dials or through the convenience of our handheld Infrared Setting Unit.
Diversa PIR sensors are available in recessed ceiling and wall switch formats and are competitive with other PIR sensors in the market, but
offer quick, easy installation and are factory configured for the most common uses. Our PIR sensors also offer features and configurations
that can be set with on-board switches and dials.

Applications
Lighting control systems suitable for
a variety of applications.
Classroom or Open Office
Private Office
To detect major and minor motion across a large area, dual
technology recessed ceiling sensors (WOR series) provide the
most complete coverage. For areas with plenty of natural light,
adding photo sensors and dimming options can supplement
natural lighting when needed while reducing electrical costs.
To identify occupancy in a small defined area, a wall switch
with (WOS series) sensor can suffice, eliminating the need
for running wire to a ceiling or corner mount sensor.
Depending on the room layout and frequency of motion,
a dual technology sensors may be the best solution to avoid
false off actions.
Hallway or Stairway
Foot traffic can be frequent or infrequent depending on the
time of day and traffic patterns. Ensure lights go on and stay
on when needed by installing corner mount (WOW series)
sensors that can be easily directed to specific areas or cover
long narrow areas. Generally these are major motion areas
so single technology sensors would work well.
Conference Rooms or Library
To detect major and minor motion across a large area that
has obstructions such as partitions and room accessories,
dual technology ceiling mounted sensors can provide the
most complete coverage.
Lunch Rooms
These rooms are used intermittently throughout the day and
as such are an easy place to save energy by turning the lights
off when not occupied. When the room is occupied there
tends to be less movement, but more conversations, so dual
technology sensors would work well in this application.
8
Reception Areas
Restroom (partitioned)
These areas experience common patterns of traffic. Usually
one person could be at the desk through the entire day but
have little movement while having phone conversations.
Diversa Dual Technology recessed ceiling (WOR series)
sensors with ADI-Voice will pick up on human voices to avoid
turning the lights off when the space is occupied.
Public restroom will have partition walls and obstructed views
to wall sensors, therefore a Dual Technology ceiling WOR
series sensor would work well in these applications. 2-pole
models are available to control lights and fans.
Restroom (private)
Private restrooms see infrequent use and have a clean line of
sight across the small space. Diversa Single Technology wall
switches (WOS series) work well in the application. The timer
can be adjusted and 2-pole models can control lights and
fans.
Storage Rooms/Closets
These types of spaces tend to be accessed infrequently, for
short periods of time. People also find they may at times be
carrying something in or out of the rooms so switching lights
on and off can be a challenge. By using a PIR wall switch
(WOS series), convenience and energy savings are instantly
achieved.
Atrium
Atrium spaces can be large with very high ceilings, making
the installation of sensor challenging. Corner mount (WOW
series) sensors can be mounted around the perimeter of the
area and directed to entry and walking spaces to monitor
occupancy and control lights.
9
Functionality
Smart Sense
Restroom Mode (PIR 2-pole only)
When occupancy is no longer detected and lights time out,
PIR and ADI-Voice detection stay active for 30 seconds to
immediately reactivate the lights through motion or voice.
Once Smart Sense has expired, sensors would operate as
configured (vacancy switches would require a manual light
switch for switching lights ON; dual technology sensors would
require motion to be detected by PIR to switch lights on and
activate ADI-Voice).
Allows pole delay timer to be synchronized for both pole or
Offset (pole 2 OFF delay is extended 50% longer than pole 1
as set on time delay dial) e.g. - a room fan connected to pole
2 would stay on for 15 minutes if time delay for light (pole 1)
set at 10 minutes.
Self-Adapting Technology
Natural light is used in a room until light level drops below
Light Level dial set point. Lights are then activated to provide
additional illumination.
Diversa sensors have an Auto Mode which learns vacancy
tendencies rather than manually setting the vacancy timer for
a predetermined period of time. This technology can save
energy by understanding how long a time delay is needed.
Walk Through Mode
Lights are switched OFF after 3 minutes if occupancy not
detected after 30 seconds of initial detection (lights ON)
saving energy by shortening the OFF delay when a quick
entrance and exit occurs.
Sensor Link
Sensor Link communication network for Diversa low voltage
(24Vac) sensors. Sensor Link allows up to 10 sensors to
communicate and coordinate their actions to act as a one
cohesive zone. Sensor Link also provides additional control
functions:
•By using a low voltage diode pulse light switch connected
to the Sensor Link network, manual control over the lights
can be achieved. Multi-level sequencing can be achieved
by using 2-pole sensors.
•Maintained AC: Sensor control is disabled while AC is
provided to the Sensor Link network (e.g. reception area
remains lit during business hours, but after hours lights will
only switch on when motion is detected - AC into Sensor
Link network is managed through a time-of-day controller).
10
Natural Daylight Mode (models with photo
sensor)
Light Level Mode (models with photo sensor
and dimming)
Closed Loop Control of the light level. Lights come on and
self-adjust to the light level set point when there is insufficient
natural daylight.
Relay Control
Diversa low voltage sensors can control up to 4 relays through
a diode pulse signal.
Configurable Options
Each building is unique in its lighting control needs.
Diversa sensors provide the user with a wide variety
of configuration options, to ensure each buildings
individual needs are met.
•Time delay for switching lights OFF: 30 seconds to 30 minutes (up to 120 minutes with Infrared Setting Unit)
and Auto (factory default 10 minutes)
•Adjustable PIR Sensitivity
•Adjustable ADI-Voice sensitivity
•Disable ADI-Voice Detection
