echoflex MOS-IR-xA Ceiling and High Bay Occupancy Sensor Installation Guide

echoflex MOS-IR-xA Ceiling and High Bay Occupancy Sensor

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

• PIR sensing must have an unobstructed view of the space. Do not mount behind or near tall cabinets, shelves, or hanging light fixtures.
• Avoid locating the sensor where it can easily sense movement outside of the intended space, such as hallways, glass partitions, or adjacent rooms. If these conditions are unavoidable, use lens mask stickers to block off specific areas. See Lens Masking on page 4.
• Do not install within 2.5 m (8 ft) of an HVAC airflow duct or vent.

Supplies required to install (not provided)

• Two #6 screws, double-sided tape, or Velcro®

Installation

The sensor can be attached to a suspended ceiling or finished wallboard ceiling. An auxiliary mounting plate with integrated magnets is also provided. Determine the installation method and follow the instructions.
Note: Consider linking the MOS while you have access and before replacing the cover. See the Link to a Controller on page 4.

Wire Staples to Ceiling Tile

1. Remove the sensor cover to access the mounting pinholes.
2. Mark the sensor mounting location on the ceiling tile.
3. Remove the ceiling tile from the T-bar frame.
4. Insert the wire staples (provided) through the pinholes on the sensor, one set located on each side near the keyholes.
5. Poke the tines through the ceiling tile, then bend each tine over in opposite directions for a secure fit.
6. Replace the ceiling tile and reattach the sensor cover.

Wallboard Ceiling

1. Remove the sensor cover to access the mounting keyholes.
2. Mark the location of the keyholes on the ceiling.
3. Bore two holes and insert screw anchors (not provided).
4. Attach the sensor to the ceiling with screws (not provided).
5. Replace the sensor cover.

Integrated Magnets
Attach the sensor directly to the suspended ceiling T-bar frame using the auxiliary mounting plate’s integrated magnets.

Adhesive
Use double-sided tape or Velcro (not provided). Cut a piece of double-sided adhesive tape or adhesive-backed Velcro to the appropriate length and press firmly in place.

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 for up to seven days for the DT models, and nine days for the PIR. It can operate with 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 30- the second window and set 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 is 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.
• When the space is vacant and the controller is configured for occupancy, a PIR detection or manual control can change the state to occupy.
• When the space is vacant and the controller is configured for the vacancy, only manual control can change the state to occupy.
• 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 occupy if the sensor is configured for occupancy.
• When audio is detected in an occupied space, the sensor’s
• The 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
• A timer allows an occupant sufficient time to use sound to reset the sensor’s Occupancy Timer.

Lens Masking 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.

Link to a Controller
The compatible target controller must be installed, powered, and within range of the MOS.
Note: The linking process can be used both to link a device to a controller and to unlink a linked device from a controller.

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.
