Sensor Description
The MOS-MT IoT ceiling sensor is a self-powered wireless sensor offering
occupant detection, light level, temperature and sound level monitoring for
the collection of and sharing of data for Internet of Things. Facility operations
use the IoT sensor data via gateways or interfaces to track occupancy levels
and environment mapping for building-use optimization. Areas not being
used can be placed into set-back mode to conserve energy. The detector is
optimized for ceiling heights of 8 - 10 feet (2.4 - 3 meters).
These sensors are intended for indoor use only.
Note:
The MOS is a solar powered device that absorbs solar energy
storing it for use during low light periods. Before assigning
the MOS device to a receiver/controller, the device should be
exposed to a good light source for a minimum of 5 minutes
or install the start assist battery.

Sensor Operation
The MOS-MT IoT sensor monitors occupancy, light level, temperature and
sound level in interior spaces. The sensor is powered by solar energy from
natural or articial light sources. Powered by six solar cells, the sensor can
operate without battery up to 5 days. The sensor will operate even with
a brief exposure to light, however for best results the sensor should be
mounted in a location with exposure for 2.5 hours of natural or articial light
(minimum of 500 lux or 46 foot-candles) on a daily basis.
The sensor must be within range of any receiving gateway or interface. The
MOS-MT and gateway/interface should be installed within 80’ (24m) of
each other. For applications exceeding 80’ (24m) range, telegram repeaters
may be needed to extend reception range.
Wireless System Layout Hint
• Reception range of 24 m (80 ft) - commercial ofce spaces (typical), up
to 100m (330 ft) line of sight
• Avoid locating transmitters and receivers on the same wall.
• Avoid locating transmitters and receivers where the telegrams must
penetrate walls at acute angles. This increases the material the telegram
must pass through reducing the signal power.
• Avoid large metal obstructions as they create radio shadows. Place
receivers in alternate locations to avoid the shadow or use repeaters to
go around the obstacle.
• Do not locate receivers close to other high frequency transmitters.
• Leave at least 3’ between the receiver and any other source of
interference including, ballasts, LED drivers, computers, video
equipment, Wi-Fi/LAN routers, GSM modems and monitors.
Sensor Range
The sensor is offered with different lens options.
There is a lens with a high sensor ray density pattern (lens A) suitable for small
motion detection, however this lens has shorter detection range.

Mounting the Sensor
The mounting location of the sensor is important as this will directly affect
the receivers reception of the telegrams. Before installing, refer to the
sections in the guide detailing the installation of wireless devices, layout tips
and test operation modes.
iNote: The sensor cannot detect motion through solid objects including
items placed by a tenant, such as le cabinets or shelves.
iNote: Do not locate the sensor near forced air vents as hot moving air may
cause the sensor to false trigger movement. Leave at least 4’ (1.2 m)
minimum between air vents and the sensor
For the best sensor performance, mount the sensor so at least one of the
solar cells is facing a light xture. The sensor will operate in low light levels
however for best performance, a minimum of 5 foot candles (54 lux) must
be maintained. If the controlled lights in the space are dimmable either
manually or via daylight harvesting, insure the light level at the lowest
dimmed level meets this 5 FC requirement. If the light value does not meet
this requirement, install a battery.
Installing or Replacing the Start Assist Battery
The battery is not required for normal operation. The battery (model CR2032)
may be useful for installation purposes (test mode operation and linking) or
for applications where there are long periods of no light.
1. Using a small screwdriver for leverage, insert under the clear plastic
cover at one of the relief tabs in the base plate and pull up. You will
need to repeat with at least two tabs until the cover pops free.
2. Using a small at head screwdriver or pen as a lever, insert pointed
end under the clear plastic battery retaining clip’s edge and pop the
clip off. Using a nger, remove the old battery by pulling the battery
free from the holder.
3. Insert the new CR2032 coin cell battery with the + positive side facing
up and press in place with your nger.
4. Align the two straight edges of the retaining clip with the battery
holder and press the clip in with your nger.
5. Replace the cover over the sensor aligning the button hole with the
teach button and press in place.
