A BRAND YOU CAN TRUST
13
Since 1987, Sensor Switch has been the
leader in lighting control innovation. Now, as
part of the Acuity Brands portfolio of lighting
and controls solutions, we’re delivering even
more products and services for all your
lighting needs.
A BRAND YOU CAN TRUST
13
LONG LIFE
12
Advanced relay switching techniques protect
relays and provide extended relay life even in
electrically challenging applications (e.g., large
loads of T5 lighting).
LONG LIFE
12
• Patented Relay Contact Protection provides unsurpassed
robustness to power packs
• Prevents mechanical wear on contacts by absorbing
inrush from electronic ballasts
• Available on PP20 and SP20 units
• Tested to over 400,000 cycles
• Competitors power packs comparable to our
MP20/MSP20 line of power packs (no contact protection)
ULTRA-LOW POWER
CONSUMPTION
11
Low voltage sensors (both PIR and Passive Dual
Technology) draw very low current, enabling
14+ to be connected to one power pack
(compared to <5 of other brands).
ULTRA-LOW POWER
CONSUMPTION
Key advantages of lower power draw
11
•Overall fewer design constraints
•More cost effective application into large areas that
require multiple sensors (open offices, cafeterias, long
corridors) as fewer power packs are required.
•Simpler application of sensors into applications with
lighting panels as less power is required from panel.
FAILSAFE INSTALLATION
10
Reversible line & load connections…
…impossible to wire backwards
•Line voltage sensors utilize two reversible black wires for
connection to line and load.
•Patented feature ensures that the sensor cannot be wired
backwards – a condition which causes other brands’
sensors to be damaged
SIMPLE PROGRAMMING
All digital push-button programming allows you
to adjust settings without tools; no analog dials,
pots, or dip switches required.
9
SIMPLE PROGRAMMING
• Allows for precise selection of settings
9
• Provides access to advanced features not normally
provided with competitors products
• Provides positive user feedback during programming
• Facility owners feel comfortable adjusting basic settings
themselves without a contractor call back
SELF-CALIBRATING DAYLIGHT
CONTROLS
All photocells have an automatic set-point
calibration mode that can be run at any time
of the day and in any daylight conditions.
8
SELF-CALIBRATING DAYLIGHT
CONTROLS
• Close loop technology ensures user convenience
is assured and minimizes importance of location
8
• “Deadband” is recalculated every cycle. This prevents
changes to the rooms carpet, paint, and/or lamp aging
or outage from effecting photocell performance.
• Every sensor is calibrated as a foot-candle meter.
• Automatic Dimming (ADC) and Occupancy Controlled
Dimming (D) options not offered with other brands
RETROFIT MADE EASY
7
Because of their ultra-low power requirements,
wall switch sensors require no neutral connection
– even two-pole dual technology versions!
Additionally, low voltage sensors are compatible
with other brands’ power packs, allowing for
seamless transitions when converting from other
brands.
RETROFIT MADE EASY
7
• Important in retrofit applications as existing switch
legs often are only two wires (hot and load) with no neutral
• NEC and UL allow very low current to be pulled over ground
connection (GFI’s trip ~4-6 mA)
• Sensor Switch products are engineered to draw
ultra-low current (<500 microamps (µA))
• Since Microphonics is a completely passive technology it also
requires very low current to function
• Sensors using Ultrasonic draw more current than allowed, thus
requirement for neutral wire
LAMP-MAXIMIZING TECHNOLOGY
6
Patent pending LampMaximizer® technology (standard
in most sensors) allows users to aggressively target
energy saving while still protecting lamp life. A minimum
on timer prevents lamp cycles shorter than
manufacturer recommendations. Additional optimizing
features further enhance energy savings and lamp life.
LAMP-MAXIMIZING TECHNOLOGY
What is LampMaximizer® Technology?
6
• Patent pending sensor intelligence that enables users to aggressively
target energy savings while still protecting lamp life
• Three feature sets: LampMaximizer, LampMaximizer+ , and Lamp
Statistics
LampMaximizer
Basic feature set that includes two timers; one minimum on timer and
one standard occupancy time delay
LampMaximizer+ (disabled by default)
Advanced operational mode that automatically adjusts occupancy
time delay such that lamp life & energy savings are optimized
Lamp Statistics
Sensor maintains statistics on lamp on time and number of cycles
LAMP-MAXIMIZING TECHNOLOGY
What is the LampMaximizer® Minimum On Timer?
• Sensors utilize two timers instead of just one
6
1. Minimum On Timer (15 min default) – preserves lamp life by eliminating
all lamp cycles shorter than lamp manufacturers recommendations.
2. Standard occupancy time delay (10 min default) – lower time delay
increases energy savings
• Both timers are user adjustable via push-button
• Test mode provided to enable convenient and quick
operational testing

Disables minimum on timer
Sets Occupancy Time Delay to 30 sec
Reduces photocell transition periods to < 5 sec
Speeds up dimming rates to maximum
Sensor will revert to normal operation if left in test mode for 10 min
GREATER ENERGY SAVINGS
Sensors are set to a default 10 minute
occupancy time delay, while other brands use
15 minutes or longer. This provides for
greater energy savings and underscores our
faith in our detection abilities.

100% ACOUSTICALLY PASSIVE
Sensors emit no high frequency ultrasonic or
microwave transmissions. No potential for
interference and none of the headaches
common with other detection technologies.
4
100% ACOUSTICALLY PASSIVE
• Ultrasonic sensors have had issues in the past
with interfering with some hearing aides
• As a result, NEMA commissioned studies and
created guidelines to prevent future problems
• The fact that NEMA created guidelines
underscores the fact that the potential of
interference will always exist with Ultrasonic
technology
4
100% ACOUSTICALLY PASSIVE
• Ultrasonic sensors interfering with wireless
microphones has been encountered in the field

• Mimio® electronic white-board readers utilize an
Ultrasonic pen which is rendered useless if
Ultrasonic sensors are active in the classroom

PASSIVE DUAL TECHNOLOGY
(PIR / MICROPHONICS)
Sensors both see occupants motion and hear
the sounds they make. This technology is
more effective than technologies that only
detect motion (e.g., Ultrasonic/PIR) and
eliminates false-offs.
3
PASSIVE DUAL TECHNOLOGY
(PIR / MICROPHONICS)
What Is Microphonics?
3
• Detection technology using a microphone inside of the sensor
to hear sounds indicating occupancy
• Common applications are rooms with obstructions, such as
bathrooms with stalls or open office cubicle areas
• Never used by itself, Microphonics is always coupled with PIR
• Referred to as having Passive Dual Technology (PDT), occupant
motion must initially be seen by the PIR to turn the lights on,
after which occupants can either be seen (via PIR) or heard (via
Microphonics) for the lights to remain on
PASSIVE DUAL TECHNOLOGY
(PIR / MICROPHONICS)
How Is Microphonics Different Than Ultrasonic
Technology?
• Better & more reliable detection
• No false ons from common
building motion
• Detecting both sound and motion
results in better occupant
detection than sensors that use
two technologies to only detect
motion (and thus no false offs).
• Requires less power
3
PASSIVE DUAL TECHNOLOGY
(PIR / MICROPHONICS)
How does Microphonics work in a noisy space?
3
• Only detects leading edge noises typical of human activity (e.g., talking,
typing, rustling papers, etc.)
• Filters out building noises (e.g., HVAC rumbles or air currents).
• Automatic gain control (AGC) techniques are used to dynamically self-adapt a
sensor to its environment by filtering out constant background noise.
PASSIVE DUAL TECHNOLOGY
(PIR / MICROPHONICS)
Additional Microphonics Intelligence
3
• Advanced digital acoustic filtering prevents the prolonged presence of
varying noises without any PIR events, such as leaving a television or
radio on, from keeping the lights on.
• Sensors doubles Microphonics
threshold every 30 min if only
sounds are being picked up
without any PIR.
• A single new PIR event will
return sensor back to original
threshold, if none lights will
eventually go out
Microphonics Sensitivity Over Time
(assuming no PIR hits)
Minutes of no PIR hits
PASSIVE DUAL TECHNOLOGY
(PIR / MICROPHONICS)
Additional Microphonics Intelligence
3
• Sounds with periodicity, such as consistent clicks from a clock, are also
filtered out
• Microphone “observes” retrips caused by spikes of electrical noise on the
line right after a load is switched off and “locks them out”
• Microphone knows the sound of its own relay switching and filters it out
• Microphone is left on for 10 sec after lights are turned off to allow for
voice reactivation
