echoflex OWS-IR-UW-120 277 Wall Switch Sensor OWS Installation Guide

echoflex OWS-IR-UW-120 277 Wall Switch Sensor OWS

Overview

The Wall Switch Sensor (OWS) combines a switch for manual control of lights and an occupancy sensor that uses standard passive infrared (PIR) or Dual Technology to monitor occupancy and transmit status wirelessly. The sensor fits well in applicationswhere energy codes require the lights to be manually turned ON and automatically turned OFF when the space is vacant. It is available as a line-powered or battery-powered model. The line-powered models are no-neutral conductor devices that connect to line voltage and earth ground. Battery-powered models can operate for 12 years in typical office use conditions.

The Dual Tech models use PIR and passive microphone technology to provide full coverage of audible human activity. Innovative noise filtering prevents false triggers that could keep lights on in empty spaces. This document covers installation, testing, and settings that apply to all OWS models. The product package includes the sensor and two mounting screws. Battery-powered models include non-replaceable lithium batteries. A white faceplate is sold separately (part number: HW8563).

Prepare for Installation

To ensure optimal function, consider the installation environment and the following guidelines:

• For indoor use only. Operating temperature -10°C to 45°C (14°F to 113°F), 5%–92% relative humidity (non-condensing).
• High density construction materials and large metal appliances or fixtures in the space may disrupt wireless transmissions.
• Install the sensor within range of linked receivers or controllers, 24 m (80 ft). Consider adding a repeater to extend reception range.
• Avoid locating the sensor where it can easily sense movement outside of the intended space, such as hallways or adjacent rooms.
• The warnings and IMPORTANT SAFEGUARDS on the facing page apply to line-powered models.

2. Make sure the antenna wire is seated in the antenna channel as shipped. Do not cut or cap the antenna wire.
3. Remove the faceplate from the junction box.
4. Do one of the following according to the model:
5. For battery-powered models, ensure the junction box is suitable and safe; clear of debris and existing wires are capped.
6. For line-powered models, refer to the Wiring Instructions below to connect the line power and ground. Use wire nuts on all connections.
7. Attach the OWS to the junction box with the two screws (provided) through the oval mounting holes.
8. Restore power to the circuit.
9. Install a non-metallic faceplate (not included).

Note: Consider linking the OWS while you have access and before installing the faceplate. See Link to a Controller on the facing page.

Wiring Instructions

The black (line) wire, 120 or 277 VAC, is connected to the power. The green (ground) wire is connected to the building ground and is required for proper operation and safety. The OWS is a no-neutral conductor design; a white (neutral) wire is not required. Minimum wire specifications: size 300 V, 14 AWG, 60°C (140°F).

Link to a Controller

The compatible target controller must be installed, powered, and within range of the OWS. Both the occupancy sensor and the manual switch must be linked separately using the following two processes.

Note : The linking process can be used both to link a device to a controller and to unlink a linked device from a controller.

To link the occupancy sensor:

1. Remove the OWS faceplate to access the [Teach] button on the side of the sensor.
2. Press the [Learn] button on the controller to activate Link mode. If necessary, refer to the related product documentation.
3. Press the [Teach] button once to send a link message.
4. Deactivate Link mode on the controller.

To link the manual switch:

1. Press the [Learn] button on the controller to activate Link mode. If necessary, refer to the related product documentation.
2. Click the top side of the OWS rocker switch three times quickly.
3. Deactivate Link mode on the controller

Sensor Operation

The sensor is optimized to detect small movements 3.6 m (12 ft) away and larger motion up to 11 m (36 ft) away. Dual Tech models provide an audio detection range up to 7.3 m (24 ft).

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. See Sensor Coverage on page 11.

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.

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

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 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.
