This guide covers MOS-17 models which are equipped with EnOcean 315 MHZ
radios. Models include: MOS-17CA with small moon lens - 1000 sq.. range,
MOS-17CB with large moon lens - 1900 sq. . range and the MOS17-CC for
High Bay applicaons 6300 sq. . range.
The Moon-Occupancy Sensor MOS is a wireless, energy harvesng, ceiling
mount, passive infrared (PIR) occupancy sensor. Used for indoor applicaons,
the detector is opmized for ceiling heights of 8 - 10 feet (A and B lens) or 40 feet
(C lens).
The sensor broadcasts an EnOcean telegram when occupancy is detected
and repeats transmissions with a minimum 100 second period between
subsequent telegrams.
Powered by six solar cells, the MOS can operate without baery backup for
over 90 hours. An ecient power supply and tuned sensor circuitry allows the
MOS to provide immediate response to new occupancy states making it an ideal
soluon for auto-ON applicaons.
A walk-test feature allows installers to test and verify sensor operaon on
locaon without extra tools or soware. False occupancy state tripping through
pet movements or from other elements can be reduced with an on-board slide
switch selecng a lower sensivity seng

The PIR sensor is an opcal sensor that detects moon by measuring the infrared
heat given o by objects. The sensor is calibrated to detect the heat range of
human body temperature. The sensor has a lens that breaks the viewing angle of
the sensor into zones that focus the light onto dierent secons of the sensing
element. It is the movement of the infrared frequency moving in and out of a
zone that denes moon.
The infrared light emied is stronger when people are closer to the sensor.
Sensor range is measured in two planes; the ceiling height to 36” o the oor or
table/desk height and the second, the linear distance from the sensor.

The MOS sensor is oered with two dierent lens. There is a lens with a high
sensor ray density paern suitable for small moon detecon however this lens
has shorter range. The second lens has a broader range but is less sensive for
small moon detecon.
Sensor range can be separated into two elds of detecon:
1. Small moon - this is the area closest to the sensor and can detect small
movement such as hand waving, picking up a coee cup or answering the
phone. The small movement eecve area will decrease as the ceiling
height increases.
Do not use the MOS sensor for ceiling height applicaons where small
movement detecon is needed and the ceiling height is greater than 9 feet.
2. Large moon - this is the area surrounding the small moon area extending
to the sensor’s range limit. The further from the sensor, the more diluted
the sensor ray paern becomes requiring larger body moon such as
walking to trigger occupancy.

There are three primary objecves when nding a suitable locaon for
the sensor.
1. Placing the sensor for proper occupancy detecon.
2. Placing the sensor so the receiver in within radio range.
3. Placing the sensor so it can harvest adequate light energy.

• The sensor can not detect occupancy through solid objects including items
placed by the tenant such as le cabinets and book shelves.
• Do not locate the sensor near forced air vents as hot moving air will cause
the sensor to false trigger. Leave at least 4’ minimum between air vents
and the sensor.
• Incandescent lights can cause false trips when turning on.
• Movement perpendicular to the sensors detecon zones create stronger
signals than movement directly towards or away from the sensor. Try to
locate the sensor so movement is across the detecon paern.
• Determine what kind of primary moon will trigger the sensor - walking or
hand movements. Hand waving and other small moon is only detectable
at 6’ (1.8m) maximum from the sensor locaon when mounted on a 8’
ceiling with lens A. Walking and large moon is detectable up to 18’ (6.1m)
with lens A from the sensor on an 8’ ceiling
• In oces and classrooms that measure 40’ by 40’ (12.2m by 12.2m) or less,
one sensor is oen sucient. Centrally located, the sensor picks up the
moon on the spaces peripheral
• larger spaces will require some planning before posioning the sensors.
Determine the type of trac paerns, where occupants will be seated, and
where doors are located. Locate the sensor so the detecon paerns do
not extend out doorways.
• Hallway applicaons are mostly walking trac parallel with the detecon
paern so sensors should be mounted 30’ (9.1m) maximum from each
other as sensivity will be decreased, see diagram.
• Open oce space or other open oor plan designs require addional
sensors. Place the sensors in a grid adjusng for walls and furniture,
see diagram.

The MOS is a wireless transmier intended to be used with EnOcean lighng
control products. Locang the wireless transmiers to work with the lighng
controller requires planning. Careful consideraon should be made for locang
the controllers and transmiers based on the construcon materials in the
space and possibility of tenant’s furniture disrupng the transmissions. Fire
doors, elevator shas, stairwells, storage areas and any large metal products
create radio shadows and will disrupt wireless transmissions.

On oor-plan drawings, draw 100 feet (30m) diameter circles around the
locaon of each controller to idenfy opmal transmier locaons. Refer to
the table below for range consideraons with building materials that reduce the
radio signal power.
Use an EPM300C for on-site range tesng and locaon suitability. The EPM300C
provides the convenience of a hand-held device indicang signal strength from
transmiers. The EPM300C will verify proper signal recepon at your intended

The radio signal is aenuated by the materials that it passes through. Dense
materials require more power to pass a radio signal consuming more of the
signal strength and reducing the signal range.

You can use double sided tape or wall anchors and screws to mount the
MOS sensor.
1. Using a ngernail, insert under the clear plasc lens at one of the relief tabs
in the base plate and pull up.
2. You will need to repeat with at least two tabs unl the lens pops free.
3. Hold the sensor in place and mark the two mounng holes with a pencil.
4. Install the wall anchors and screws per the package instrucons leaving the
screws loose.
5. Place the MOS sensor so the screw heads go through the mounng holes
and slide the sensor so the screw head is holding the base plate.
6. Tighten the screws, do not over ghten.
7. Replace the lens over the sensor aligning the link buon hole with the

The MOS sensor has a slide switch that the user can use to select max. or
min. sensivity levels. False occupancy states caused by other elements
can be reduced by selecng the min. sensivity level. The default seng is
max sensivity.
To change the sensivity seng:
1. Remove the clear plasc lens by inserng a ngernail under the lens at one
of the relief tabs in the base plate and pull up.
2. Slide the switch over to the chosen seng.

2. Using your ngers, remove the old baery by pulling the baery free from

The walk-test feature allows the installer to test the placement of the sensor
with the intended space usage paerns. An area where small hand movements
shall trigger the sensor can be tested during installaon to insure that the sensor
is close enough to the area for this detecon paern.
NOTE: The MOS sensor should be allowed to charge in a strong light source before using
the walk-test feature.
1. Press the link buon to start the walk test.
2. An on-board led will blink when moon is detected. The led should be
clearly visible as the walk test is performed.
3. The walk test will me out aer approximately 60 seconds and resume
normal operaon.

• Avoid transming down a length of wall to reduce signal reecon.
• Avoid transmissions that must penetrate walls at acute angles. This
increases the wall material the telegram must pass through, greatly
reducing the signal power.
• Avoid large obstrucons. Place receivers in alternate locaons to avoid the
radio shadow or use repeaters to go around the obstacle.
• Do not locate receivers close to other high frequency transmiers. Leave
at least 2’ between the receiver and any other source of interference
including, computers, video equipment, Wi-Fi/LAN routers, GSM
modems and monitors. Transmiers are not aected by these sources of
