Failed Vacancy Operation with Echoflex Dual-Tech Sensors

Symptoms/Issue

The lights are not shutting off after the desired period of time in a space controlled by one or more Echoflex Dual-Tech (DT) Sensors.

Description

You could be running into a situation regarding differing occupancy timers (how long it takes to enter vacancy after last detection of occupancy) OR audio sensitivity.

Regarding occupancy timers:
  • Each Echoflex controller has an internal assigned occupancy timer
  • PIR-only Echoflex occupancy/vacancy sensors use the occupancy timer of the output controller they are linked to
    • the controller occupancy timer defaults to 15 minutes
  • Dual-Tech Echoflex occupancy/vacancy sensors have their own internal occupancy timer, which makes the relationship with their linked output controller a little more complex
    • the DT sensor occupancy timer defaults to 20 minutes

There are several ways occupancy timeout works when DT sensors are linked to controllers:

  • The controller can have its timer set to 0 seconds, which essentially disables the controller's timer and makes it use the timer value of a DT sensor
  • The sensor can have its timer disabled, which:
    • if audio is still enabled, the controller uses its internal timer BUT audio detection can maintain occupancy state up to 60 minutes
    • if audio is ALSO disabled, makes it act like a PIR-only sensor (see above)
  • Both the sensor and the controller can have their timers assigned
    • if their timers match (aka both set to 10 minutes), vacancy will execute at that time
    • if the sensor has a shorter time than the controller, say 5 minutes vs 10 minutes, the lights would go out after 10 minutes since the controller only listens to 'occupied' messages in this state and will not execute vacancy until those 10 minutes are up
    • if the sensor has a longer time than the controller, say 10 minutes vs 5 minutes, the lights would go out after 5 minutes since the controller did not receive any 'occupied' messages int hat time
Regarding Audio Sensitivity:

Echoflex dual-technology sensors include passive infra-red (motion) and audio components as the two occupancy detection technologies. Only PIR motion detection can ACTIVATE occupancy. Once the space is occupied, PIR or audio detection can keep the space occupied and the lights on. The audio input does have some noise filtering to eliminate consistent background noise like a humming fan but can be kept active if the environment has sporadic noise.

NOTE: There is a timer in the dual-tech sensors which will shut the audio input off after 60 minutes without any PIR detection. The lights will shut off after the audio is off and there is no PIR activity.

Solution

To ensure proper functionality, you can:
  • adjust the occupancy timer for the sensor and/or controller
  • adjust audio sensitivity
  • disable audio detection completely

You can do this manually using SimpleTap or via commissioning software. Manual steps are below:

Change or disable occupancy timer for SENSOR:
  1. You will need to access the sensor's TEACH button to make the following changes. Make sure the sensor is fully charged or insert a battery before proceeding.
  2. Press and hold the TEACH button about 6 seconds. All the LEDs will blink together once, then the red LED only will continue to blink.
  3. Tap the TEACH button until the red and amber LEDs are blinking together.
  4. Press and hold the button until the LED stops blinking, about 6 seconds. Release the button.
  5. One of the LEDs will begin blinking again. Tap TEACH until the red LED is 'double blinking' (two blinks, pause, repeat).
  6. Press and hold the button for about 6 seconds.
  7. The red LED blinking will indicate the setting.
    1. 1 blink: disabled
    2. 2 blinks: 5 minutes
    3. 3 blinks: 10 minutes
    4. 4 blinks: 15 minutes
    5. 5 blinks: 20 minutes
    6. 6 blinks: 25 minutes
  8. Tap TEACH until you see the desired blink pattern.
  9. Save the setting by press and holding the button until all LEDs blink twice, about 6 seconds.
Change or disable occupancy timer for CONTROLLER:
  1. You will need to access the sensor's TEACH button to make the following changes. Make sure the sensor is fully charged or insert a battery before proceeding.
  2. Make sure the controller's load is ON.
  3. Tap the TEACH button three times, which should make the load blink one of the following patterns
    1. 1 blink: 0 seconds, uses the sensor's timer
    2. 2 blinks: 5 minutes
    3. 3 blinks: 10 minutes
    4. 4 blinks: 15 minutes
    5. 5 blinks: 20 minutes
    6. 6 blinks: 25 minutes
  4. Tap the TEACH button again X number of times to set the desired time, the load should blink accordingly
    1. 3 taps: 0 seconds, uses the sensor's timer
    2. 4 taps: 5 minutes
    3. 5 taps: 10 minutes
    4. 6 taps: 15 minutes
    5. 7 taps: 20 minutes
    6. 8 taps: 25 minutes
Change Audio Sensitivity or Disable Audio Detection:
  1. You will need to access the sensor's TEACH button to make the following changes. Make sure the sensor is fully charged or insert a battery before proceeding.
  2. Press and hold the TEACH button about 6 seconds. All the LEDs will blink together once, then the red LED only will continue to blink.
  3. Tap the TEACH button until the red and amber LEDs are blinking together.
  4. Press and hold the button until the LED stops blinking, about 6 seconds. Release the button.
  5. One of the LEDs will begin blinking again. Tap TEACH until the amber LED is 'double blinking' (two blinks, pause, repeat).
  6. Press and hold the button for about 6 seconds.
  7. The amber LED blinking will indicate the current setting.
    1. 1 blink: default automatic setting
    2. 2 blinks: low sensitivity
    3. 3 blinks: audio disabled
  8. Tap the button until you see the desired blink pattern.
  9. Save the setting by press and holding the button until all LEDs blink twice, about 6 seconds.

NOTE: If you  wish to disable the audio input, press the teach button twice in step 6 so the LED is blinking 3 times. Additionally, you will also have to disable the sensors occupancy timer, see below.
