Wire Specification Sensors connect to the EchoConnect communication bus. EchoConnect is a bidirectional protocol that uses one pair of wires (data + and data -) for both data and power. ETC recommends using Belden 8471 (or approved equal) Class II wire. The total combined length of an EchoConnect wire run (using Belden 8471, or equal) may not exceed 1,640 feet (500m). All control wiring should be installed and terminated by a qualified installer and should follow standard wiring installation practices. Leave approximately 10 inches (254mm) of wiring in the back box for connection to allow slack for future service needs. ETC requires that all sensors be grounded. Pull an additional 14 AWG (1.5mm 2 ) wire for grounding when control wires are not installed in grounded metal conduit. - When using Category5 (or equivalent) cable on the EchoConnect communication bus, please note the following: - Cat5 wiring must be terminated using EchoConnect Cat5 Termination Kit and must be installed using a bus topology. Refer to the installation guide that is provided with the Cat5 Termination Kit (7186A1207) for information to terminate Cat5 wiring. - Not all topologies are supported using Cat5; careful planning is required to ensure the proper termination kits are available and the wire is pulled appropriately. Installation Environment s are intended for installation to a finished ceiling surface, ceiling tile mounted, attached to a round fixture junction box or single-gang RACO switch box. The sensor operates in ambient temperatures of 0 C to 40 C, with a maximum of 90% non-condensing humidity. ETC recommends paying special attention to the installation environment: The sensor must have an unobstructed view of the room. Do not mount behind or near tall cabinets, shelves, hanging light fixtures, etc. Do not install the sensor within eight feet from an HVAC airflow duct/ vent. Install the sensor where it cannot easily sense movement in areas outside of the intended space, such as hallways, glass partitions, or adjacent rooms. If the installation location cannot avoid these Echo Occupancy/Vacancy Sensor Page 2 of 12 Electronic Theatre Controls, Inc.
conditions, portions of the lens can be masked to block the sensor view of these undesired areas. Reference Lens Masking on page 10.

The Echo participates in an Echo system using the configured Space and Address, which are selectable using the rotary switches on the rear panel of the sensor. Additional DIP switches and the [Mode] button, also located on the rear panel, set the sensor functionality and the occupancy detected action. Set Space and Address Two rotary switches on the rear panel of the controller provide for assignment of the sensor Space and Address. By default, these switches are set to Space 1, Address 1. Commands are shared by all devices within a given space. Step 1: Set the Space rotary switch to the desired number (1 thru 16) for the space you want the sensor to control. Step 2: Set the Address rotary switch to desired address (1 thru 16) for the sensor identification in the selected space. Do not duplicate a device Address within the same Space. Echo Occupancy/Vacancy Sensor Page 6 of 12 Electronic Theatre Controls, Inc.
DIP Switch Settings DIP switches on the rear panel of the Occupancy Sensor provide for additional configuration options including Use Custom Config, Vacancy Timeout, Enable/Disable PIR detection LED, and the ability to restore the sensor to its factory defaults. DIP Switch 2 DIP switch 2 enables Custom Config which instructs the sensor to use settings that are configured using the EchoAccess Mobile App. This setting is Off by default. When Custom Config is set to Off, the default position, local DIP switch settings for Vacancy Timeout and Enable PIR LED are used. Sensor actions can be adjusted using the program [Mode] button. When Custom Config is set to On, all other local DIP switch settings are ignored. Instead, the settings made by the EchoAccess Mobile App for Vacancy Timeout, Enable PIR LED, and Occupancy actions are used. DIP Switch 3&4 DIP switch 3 & 4 set the Vacancy Timeout to 5, 15, 30 minutes, or Auto. See Vacancy Timeout on page 9. 5 min = Switches 3 and 4 are Off. 15 min = Switch 3 is Off and Switch 4 is On (default). 30 = Switch 3 is On and Switch 4 is Off. Auto = Both switches are On. See Auto Vacancy Timeout on page 10. DIP Switch 5 DIP switch 5 enables/disables the red PIR detection LED. When the switch is Off, the PIR LED disables unless it is in Walk Test mode. When set to On, the red PIR LED will illuminate the sensor lens when movement is detected. The default position is On. DIP Switch 8 DIP switch 8 provides a Restore Defaults at Boot function. The factory defaults are restored by setting this DIP switch On, and cycling power to the station. The default position is Off. DIP switches 1, 6, and 7 are not currently used and are reserved for future development. Leave them at their default Off setting. Echo Occupancy/Vacancy Sensor Page 7 of 12 Electronic Theatre Controls, Inc.
Power Up and Test Power Up All EchoConnect terminations in the system must be made before applying power to the system and sensor. When the sensor is powered up, the PIR LED illuminates for one minute for calibration and warm-up, and then returns to normal operation. Configuration Sensor configuration for Basic config mode (DIP switch 2 set to Off) can be accomplished locally on the sensor using the other available DIP switches, [MODE] button and LED, and the Auxiliary button. See Preset below, and Vacancy Timeout on page 9 for local configuration instructions. Preset The [MODE] button and LED found on the rear panel of the sensor sets the sensor into Program Mode. Both the [MODE] button and LED, and the Auxiliary A button are used for configuration of the occupancy action. The A button and Mode LED are used to program the preset that is activated with an occupancy state change. The Mode LED blinks to indicate the current preset number used. When vacancy is detected, the sensor will activate a Space Off command. When functionality other than Space Off is required, place the sensor in Custom config mode (DIP switch 2 On). Customization of the Occupancy Sensor and all actions are configured using the EchoAccess Mobile App. For more detailed information about custom configuration options available for the Echo using EchoAccess, reference the EchoAccess Mobile App integrated help system. Echo Occupancy/Vacancy Sensor Page 8 of 12 Electronic Theatre Controls, Inc.
Auxiliary button Walk Test button MODE button MODE LED rear panel view Step 1: Step 2: Step 3: Step 4: Press and hold the [MODE] button for 3 seconds to enter Program Mode. Program Mode allows adjustment of the preset that activates for occupancy detection. By default, this is Preset 1. The A button, located on the front of the sensor, blinks to indicate the preset number controlled by the occupancy action. Press and release the A button the number of times to set the new preset. (For example: press and release ten times to set Preset 10.) The A button blinks the number of the preset used for the occupancy event action. Press and release the [MODE] button to save the current setting. The Mode/Sensor count LED turns off and the A button again blinks out the saved preset index. Attach the sensor to the mounting plate by aligning the tabs on the sensor with the slots on the mounting plate, then twist clockwise until the two are locked into place. Vacancy Timeout Vacancy timeout is the amount of time the sensor waits to take action after no movement is detected. By default, vacancy timeout is set to 15 minutes (indicated by DIP switch 3 set to Off and 4 set to On). When the vacancy timeout ends, the grace period begins. When the sensor detects vacancy, the vacancy timeout period begins. If the sensor does not detect occupancy again during the vacancy timeout period, the lights turn off and a 30 second grace period begins. Echo Occupancy/Vacancy Sensor Page 9 of 12 Electronic Theatre Controls, Inc.
Grace Period The sensor features a 30 second grace period after a vacancy timeout occurs to help prevent false vacancy detection. During this grace period, if the sensor detects occupancy, it will restore the previous lighting condition. Auto Vacancy Timeout The Auto vacancy timeout setting varies vacancy the timeout between 5 and 30 minutes depending on how often it identifies an occupancy trigger after a vacancy timeout occurs (during the grace period). Lens Masking Lens masks are provided in the packaging for your convenience, used to block a section of the lens from detecting occupancy. Step 1: As needed, trim the lens mask to fit the desired area to be blocked. Step 2: Gently press down on the sensor lens, which will give only slightly, and insert the lens mask. Step 3: Rotate the lens mask around the dome to block the required area from occupancy sensing. PIR Detection The PIR detection automatically adjusts its sensitivity to eliminate nuisance tripping. When the sensor powers on, the red PIR LED illuminates for approximately 60 seconds to identify Power Up state. Sensor configuration is not allowed. During this time, no events are triggered. Echo Occupancy/Vacancy Sensor Page 10 of 12 Electronic Theatre Controls, Inc.
Test s offer a Walk Test mode which shortens the vacancy timer to 10 seconds, allowing for simple and quick verification of the sensors coverage and range in the installed space. Walk-Test mode automatically exits and the sensor returns to normal operation after 5 minutes and can be manually terminated early by pressing the [Walk Test] button. Auxiliary button Walk Test button Enable Walk Test Mode Step 1: Step 2: Step 3: Step 4: Step 5: Prepare the site for configuration. a: Make certain the sensor and lighting loads are powered and connected for control by the Echo controller. b: You will need direct access to the in order to place it into Walk Test mode. Press the [Walk Test] button on the front of the sensor to enable the Walk Test feature at the sensor. A green LED will begin to flash, indicating Walk Test is enabled and the vacancy/no vacancy occupancy timer will be shortened to 10 seconds. Move throughout the space including corners and areas that may specifically be obscured from line of sight to the sensor. Each time the sensor detects movement, the lens will illuminate red. Adjust the lens masking, if installed, blocking certain areas of the installed space from sensor detection. See Lens Masking on page 10. Walk Test mode will automatically exit after five minutes from the time it was enabled. To manually exit the Walk Test mode, press either of the buttons on the sensor.
