Sensors Communications, Connectivity, and Networking FAQ

Questions

Which wireless standards do your sensors support?

  • All Gen-5 (SU-5) sensors support IEEE 802.15.4 and Bluetooth Low Energy (BLE) v4.0

Which wireless control system communications standards does your sensor use at the physical, data link, and network layers?

  • Gen-5 (SU-5) sensors support IEEE 802.15.4 physical and data link communications. The 802.15.4 network layer is proprietary.  

What is the response latency of the sensor?

  • Sensors communicate room control (switch) activity to other sensors in the same switch group in less than 150ms.

Does the sensor network process any confidential data (e.g., individually identifiable data from devices like cameras, microphones, etc.)

  • No personally identifiable information (PII) is processed or stored by the sensor network.

How far can the sensor detect someone?    

  • Detection ranges vary by sensor and ceiling height. For additional information, see Spec Sheets.
Sensor Ceiling Height Fine Motion (Radius) Minor Motion (Radius) Major Motion (Radius)
Micro Sensor 8.5 ft/2.6 m 2.3 ft/0.7 m 8 ft/2.4 m 10 ft/3.0 m
15 ft/4.6 m 4.0 ft/1.2 m 10 ft/3.0 m 18 ft/5.5 m
Smart Sensor 20 ft/6 m 10 ft/3 m 23 ft/7 m 20 ft/6 m
40 ft/12 m 20 ft/6 m 46 ft/14 m 40 ft/12 m
Ruggedized Sensor 12 ft/3.5 m 8 ft/2.5 m 20 ft/6 m 12 ft/3.5 m
40 ft/12 m 20 ft/6 m 46 ft/14 m 40 ft/12 m


What is the light level output of the fixture before programming?

  • Non-commissioned sensors will have a default output of 65% until they are programmed. It may take up to 2 minutes after power-up for the output setting to go to 65%.   

What is the coverage a sensor can handle?

  • Enlighted recommends one sensor every 100 sq ft for indoor office applications.

What is a hopper?  

  • A hopper is used to extend the range between remote sensors and a gateway. It repeats the messages received from any sensor to improve connectivity to the gateway for these remote sensors. Enlighted recommends no more than five hoppers to be assigned per gateway (10 is the absolute maximum per gateway). See Gateway Supports 100 Sensors and 5 Hoppers.             

Why are the lights in different colors (orange/bluish/white)?

  • The color is a reflection of the color temperature of the LED fixture. Warmer fixtures are more yellow/orange and have a lower color temperature; cooler fixtures are more blue/white and have a higher color temperature.                      

Why is the sensor LED off?

  • Commissioned sensors will turn their LED off when they do not detect motion. If you move under a commissioned sensor, the green LED should blink; if it does not blink, the sensor may not have power. See LED status descriptions in the corresponding Sensor Installation guide articles. 

What does a red sensor LED mean?         

What does a blue sensor LED mean?       

Why are the lights on the un-commissioned sensors dim?

  • Un-commissioned sensors will set a default light level of 65%. In some fixtures, this may be perceived as too dim.

Why do lights turn on and off when you first power them up?

  • Lights controlled by an un-commissioned sensor may go through a wiring test procedure on start-up that will turn the lights on and off for about 30-40 seconds. Lights controlled by a commissioned sensor should not flicker unless there is a problem with the fixture/driver.
