MOS-21 Sensor Description The 21 series MOS sensor (also referred to as the sensor in this guide) is a wireless, energy harvesting, ceiling mount, passive infared (PIR) occupancy sensor. Used for indoor applications, the detector is optimized for ceiling heights of 8 - 10 feet (2.4 - 3m). MOS-21 echoflex Wireless Motion Sensor for Occupancy / Vacancy Detection with integrated diagnostic tools INSTALLATION GUIDE 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.

by solar energy from natural or artificial light sources. The solar energy is transformed into electrical energy which is then stored providing a continuous power source for the sensor. Powered by six solar cells, the sensor can operate without battery backup for up to 225 hours. 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 hours of natural or artificial light (160 - 500 lux or 16-50 fc) on a daily basis. A battery (CR2032) must be installed in the MOS-21xC sensor for use in high bay applications. The motion sensor supports the Occupancy Sensor EnOcean profile A5-07-01. The sensor will transmit occupancy or vacancy depending on the occupancy state of the room. The sensor will broadcast occupancy immediately upon a state change from vacant to occupied. The sensor broadcasts a telegram when movement is detected and repeats occupied telegrams with a minimum 100 second period between subsequent transmissions. After detecting motion, the sensor is shut-down to conserve energy for 100 seconds. When the sensor awakens and no motion is detected, the sensor transmits a vacancy telegram after 100 seconds, 200 seconds total since the previous transmission. The sensor will remain active until the next occupancy state. If the sensor does not detect motion, it resends the vacancy telegram every 1000 seconds. The sensor must be within range of any linked receivers or controllers, installed within 24m (80’) of each other. For applications exceeding 24m (80’) range, telegram repeaters may be needed to extend reception range. Motion Detection The MOS family uses a PIR sensor that detects motion by measuring the infrared energy given off 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 (movement zones). It is the movement of the infrared energy moving in and out of a zone that defines occupancy. The amount of movement that triggers the sensor is dependent upon the density of the zones where the motion takes place. A higher density of zones means smaller motion will trigger the sensor. For detection of small motion (typing, drinking from a coffee cup), use the MOS- 21A model which has a lens with more movement zones. Place the sensor close to the location where the motion may occur. A red LED under the lens will blink once every 100 seconds when the sensor detects motion.

ray density pattern (A) suitable for small motion detection, however this lens has shorter detection range. The second lens (B) has a broader range but is less sensitive for small motion detection. The third lens (C) is for high ceiling applications, for example: high bay warehouses. 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. NOTE: The sensor can not detect occupancy through solid objects including items placed by a tenant, such as file cabinets or shelves. NOTE: Do not locate the sensor near forced air vents as hot moving air may cause the sensor to false trigger. Leave at least 4’ (1.2 m) minimum between air vents and the sensor. NOTE: Incandescent lights may cause false trips when turning on. Large Range Lens (B) 1900 sq.ft @ 9 ft. Short Range Lens (A) 1000 sq.ft @ 8 ft. High Bay Lens (C) 6300 sq.ft @ 40 ft.

movement patterns that will be the most common in the space. • For smaller office spaces where hand motion on a desktop is common, locate the sensor off to one end of the desk, in line with the desk edge or slightly behind so the PIR lens has direct line-of-sight to the keyboard desktop area. Insure that the PIR lens does not have direct line-of-sight out a doorway where walk-by traffic could trigger the sensor. • Larger offices where larger body motion is more common, placement of the sensor is less critical. 2. For the best sensor performance, mount the sensor so at least one of the solar cells is facing a light fixture. The sensor will operate in low light levels however for best performance, a minimum of 4 foot candles must be maintained. If the controlled lights in the space are dimmable either manually of via daylight harvesting, insure the light level at the lowest dimmed level meets this 4 FC requirement. If the light value does not meet this requirement, install a battery. 3. Remove the cover by pushing upwards on the cover. Using a small screwdriver for leverage, insert under the clear plastic lens 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 lens pops free. 4. Choose a mounting method. The sensor can be mounted: • With the screws and anchors (not provided) to a wall-board ceiling. Use a pencil to mark the mounting base key hole locations and remove the sensor. Using a drill, bore the two holes and insert the anchors. Install the screws, leaving them loose while you place the sensor. Tighten the screws. • With double sided tape or Velcro™, not provided. Cut two lengths of tape and remove the backing. Place on the mounting surface of the sensors back plate, pressing down. Remove the backing from the tapes other side and place the sensor on the ceiling surface, pressing firmly. 5. Replace the sensor cover aligning the button hole with the teach button and press in place. 6. Refer to the section titled Linking the Sensor to a Receiver. Linking the Sensor to a Receiver This process requires the controller or receiver to be mounted and powered and within range of the sensor to be linked. 1. Activate LEARN or LINK mode at the receiver, if necessary refer to the manufacturers documentation. 2. Tap the sensors TEACH button once. 3. Deactivate LEARN mode at the receiver. NOTE: If the sensor is already linked to a controller, linking again will un-link the sensor. Installing or Replacing the Start Assist Battery The battery is not required for normal operation of the MOS-21xA and MOS- 21xB models. 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.

Wireless System Layout Hints • 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.
