  4. Option 4: Mounting Sensor onto 3/4” rigid conduit stub 

Option 1: Mounting the Sensor directly on Drywall/Sheetrock/Ceiling Tile (with or without J-box Backup)

To install the Ruggedized sensor with HCM in drywall or hard top ceiling,

  1. Drill a 1” diameter hole where the sensor is to mount

  1. Glide the coupler and excess wire into the conduit.

Note: Ensure that the cable is completely drawn out and not compressed at the end of the conduit.

  1. Press the sensor as far as possible into the conduit.

Option 3: Mounting Sensor into 3/4” EMT Conduit Stub 

To install the Ruggedized Sensor into a 3/4” EMT conduit stub please make sure that you have access to the fixture side of the stub.

  1. Stretch the HCM carrier to insert it over the sensor nipple over the sensor nipple in “normal” orientation with the flange facing towards the sensor.

  1. Attach a ¾” EMT coupler to the end of the EMT conduit stub.
  2. Glide the sensor cable through the coupler and EMT conduit stub into the conduit body, J-box, or a fixture at the other end of the stub.
  3. On the fixture side of the stub, connect the RJ-45 connector or RJ-45 coupler with the extension cable from the sensor to the CU.

  1. On the sensor side of the stub, glide the excess wire into the conduit.

Note: Ensure that the cable is completely drawn out and not compressed at the end of the conduit.

  1. Press the sensor as far as possible into the coupler.
  2. Tighten the screw on the coupler if it is accessible. Ensure that the screw is not overtightened.

Option 4: Mounting Sensor into 3/4” Rigid Conduit Stub  

To install the Ruggedized Sensor into a 3/4” rigid conduit stub, you must have access to the fixture side of the stub.

  1. Stretch the HCM carrier to insert it over the sensor nipple in “normal” orientation with the flange facing towards the sensor.

SU-5 Sensor Bluetooth Low Energy (BLE) Capabilities

This Application Note is intended for anyone interested in understanding the Bluetooth Low Energy (BLE) capabilities supported by Enlighted’s SU-5 sensors and how these capabilities might be used for custom applications.

Overview

An Enlighted SU-5E sensor contains a BLE radio capable of receiving or transmitting BLE advertising beacons. The Enlighted Where application uses the sensor network to receive BLE advertising messages from BLE tags to provide Real-Time Location Services (RTLS). There are limitations regarding how the sensor or the Where application can be used for custom applications.

BLE Receive Mode

By default, the BLE radio is turned off when a sensor is commissioned. You can enable the BLE functionality in either Receive or Transmit (Beacon) mode in Manage. Refer to the article Set Bluetooth (BLE) Mode. When a sensor is set in Receive mode, the sensor can only receive BLE messages that conform to Enlighted’s manufacturer-specific advertising format. Tags, such as Badge and Asset tags that support Enlighted’s advertising format, also contain an accelerometer that will change the tag's advertising interval based on the tag's movement.

Enlighted’s Where application uses sensor location, tag information, and Received Signal Strength (RSSI) of the tag to locate the tag on the building floor plan.  The Where application does not provide location services for tags, not advertising the Enlighted format. 

Currently, there is no API that provides access to the raw BLE advertising messages received by the sensor. Therefore, an Enlighted sensor network cannot be used to support 3rd-party RTLS applications, irrespective of whether Enlighted tags or 3rd party tags generate the BLE messages.

Transmit Mode

When a sensor is set to Transmit (beacon) mode, the sensor will transmit BLE advertising messages in the iBeacon format every 500 msecs at 0dBm.  Any device capable of understanding iBeacon messages and within the sensor's range can receive and process the sensor’s advertisements.

The specifics of the iBeacon advertisement are as follows:

1. Company ID (Apple Company ID): 0x004c
2. Device Type (Standard iBeacon): 0x02
3. Beacon Format Fields:

  • UUID (16 bytes): 441651aa-4036-11e6-beb8-9e71128cae77
  • Major/Minor Field Information (4 bytes) contains lowest 3 bytes of sensor’s MAC address
              Upper 8 bits of Major - always 0
              Lower 8 bits of Major – MAC address [2]
              Upper 8 bits of Minor - MAC address [1]
              Lower 8 bits of Minor - MAC address [0]
  • BLE Transmit Power (1 byte).
    Note that this message does not contain any user-definable location or geospatial information.

4. BLE TX Power Setting: 0 dBm
5. BLE Beacon Interval: 500ms

6. BLE range depends on surroundings, radio performance, and antennas. Typically, the BLE range should
    be 50 feet radius in line of sight.

Fixtureless Sensors

When a sensor is installed and configured without connection to a fixture, the sensor is called a “fixtureless sensor” and identified as such in Enlighted Manage.

Adding such sensors will increase the sensor density in a facility and improve the accuracy of the Where application. Any improvement to 3rd-party RTLS application accuracy due to additional fixtureless sensors is unknown since the beaconing sensors do not transmit location or geospatial information.
