Ceiling & High Bay Occupancy Sensor MOS
Overview
The Ceiling & High Bay Occupancy Sensor (MOS) is a wireless, energy
harvesting sensor that is available as either a passive infrared (PIR) or a
Dual Technology model. The Dual Tech sensor uses PIR and passive
microphone technology to provide full coverage of audible human activity
across the entire PIR detection range. Innovative noise filtering prevents
false triggers that could keep lights on in empty spaces.

Ceiling & High Bay Occupancy Sensor
Sensor Operation
The sensor's six solar cells harvest and store energy from natural or
artificial light sources and provide sufficient power to operate without a
battery up to seven days for the DT models, and nine days for the PIR. It
can operate with a brief exposure to light, however for best results the
sensor should be exposed to two hours of natural or artificial light
(160lux or 15 footcandles) on a daily basis. A CR2032 coin battery must
be installed in the MOS-IR-xC sensor for use in high bay applications.
Sensing Technology
PIR sensing is calibrated to detect motion in the heat range of human
bodies. The sensor is more sensitive to movements that cross the
detection zones than those moving toward or away from the detection
zones. The closer the movement is to the sensor, the more sensitive the
sensor's response. The detection zones in lens A are designed to detect
small motion (typing, desktop activity). See Sensor Coverage on page9.
Audio sensing filters out background noise level averaged over a 30-
second window and sets its threshold slightly higher. If sound exceeds the
threshold while the timers are active, the sensor’s occupied state is
maintained. For example, if a fan is running in the background of an
occupied space, only a sound slightly louder than the fan registers.
Key Timers
The Audio Enabled Timer defines the maximum duration that audio
sensing is active. Each PIR detection resets the Audio Enabled Timer. The
timer setting is 60 minutes and is not configurable.
The Sensor Occupancy Timer defines the time that detection, PIR or
audio sensing, is required to keep the audio active. Each audio or PIR
event resets the timer. The default setting is 20 minutes and is
configurable.
The sensor transmits an occupied message to the controller:
•
Minimum every 100 seconds, or
•
Immediately when a change to the occupied state is detected
Echoflex controllers also have a configurable occupancy timer that
controls when the lights shut off after a period of vacancy. See the
controller’s Configuration Guide for details on setting up timers and
occupancy or vacancy modes of control.
PIR Sensing Only (IR Models)
For PIR sensing only, the following logic is used:
•
When the space is occupied, PIR detection and manual control can
keep the lights on and reset the controller’s Occupancy Timer.
Ceiling & High Bay Occupancy Sensor Page 3 of 12 Echoflex

Echoflex Installation Guide
Ceiling & High Bay Occupancy Sensor
•
When the space is vacant and the controller is configured for
occupancy, a PIR detection or manual control can change the state
to occupied.
•
When the space is vacant and the controller is configured for
vacancy, only manual control can change the state to occupied.
•
A vacancy message is sent after 200 seconds of inactivity, and then
subsequent messages every 1000 seconds.
Dual Technology (DT Models)
When both PIR and audio sensing are enabled, the following logic is used:
•
When the space is occupied, PIR and audio detection can reset both
the sensor’s Occupancy Timer and the controller’s Occupancy Timer.
•
When the space is vacant and all timers have expired, only PIR
detection or manual control can change the state to occupied, if the
sensor is configured for occupancy.
•
When audio is detected in an occupied space, the sensor’s
Occupancy Timer is reset, but not the Audio Enabled Timer; it expires
after 60 minutes or is reset by PIR detection.
•
A vacancy message is sent after 20 minutes (default) of no detection,
then 40 seconds later the audio is disabled. The 40-second grace
timer allows an occupant sufficient time to use sound to reset the
sensor’s Occupancy Timer.
Lens Masking
Peel and stick lens mask
Teach button
Lens mask stickers are provided to
block a section of the lens from
detecting occupancy. To attach,
remove the backing and stick the mask
on the sensor lens to cover the target
section. Cut to size, if required.

Battery Power
A battery is not required for normal operation of A and B lens models if
the sensor receives adequate natural or artificial light. See the table in the
Light Level Test below. A CR2032 battery (not provided) may be required
to run installation tests or when the artificial light is insufficient to power
the sensor.
A CR2032 is included with the MOS IR*C lens model. The battery may be
factory installed or packed separately according to shipping regulations.
Insert the battery if required or remove the protective plastic tab before
installing the MOS.
1. Insert a precision flatblade screwdriver under the clear plastic cover at
one of the release tabs in the base plate and pull up. Repeat with at
least two tabs until the cover pops free.
