Resetting the Sensor

To power reset the sensor to default factory settings, press and hold the reset button until the LED stops blinking (approx 10 seconds). The sensor must be plugged in and connected to power in order to reset.

Sensor LED Status Indicator

The sensor has an indicator LED located on the front of the sensor. The color chart to the right explains the meaning of each color, defines any issues, and lists what actions to take if necessary.
If the recommended action does not resolve the LED light error status, factory reset the sensor. To reset, press and hold the reset button on the side of the sensor until the LED light starts flashing white. If the issue persists, please reach out to support@density.io

is receiving power from source
White| Solid| Operating normally| No action needed
White| Flashing| Indicates where sensor is when selecting “Locate” in Unit Setup App| Triggered via Unit Setup App
Blue| Solid| Sensor is ready for provisioning| Typical state out of the box once sufficient power is provide.
Blue| Flashing| Sensor is provisioning| Triggered via Unit Setup App. This process may take 5-10 minutes.
Orange| Flashing| Low power mode| Confirm switch is PoE+ with at least 30W per port or test ethernet cable
Purple| Solid| Sensor cannot connect to Density server| Provision sensor via Unit Setup app and if not resolved, run Validation in same app
Purple| Flashing| Server cannot connect to DNS| Verify DNS is available on VLAN. If no internal DNS server, review corporate firewalls to verify device can reach default DNS servers.
Red| Solid| Sensor does not have a Network Configuration| If using Wi-Fi, use the Unit Setup app to create a Network Template. If using ethernet, verify DHCP server is available on VLAN.
Red| Flashing| Bluetooth dongle not present| Occurs when device has not yet been provisioned and the Bluetooth Dongle is absent. Plug in Bluetooth Dongle to provision.

Power

Power Requirements

The OA Sensor can be powered by ei1 802.3af PoE switch or a PoE Injector V

Cable Requirements

The sensor requires a Cat 5e or later ethernet cable (not included). Flat white cable recommended for optimal aesthetics.

Option 1 – PoE+ Switch

Connect one end of a Cat 5e or later ethernet cable to a 802.3af compliant network switch capable of providing 16W per port. Plug the other end of the ethernet cable into the OA Sensor.

Option 2 – PoE+ Injector Using Wi-Fi

Plug the PoE Injector into any standard 120v wall outlet. Plug one end of a Cat 5e or later ethernet cable into the Data & Power Out port located on the bottom of the injector. Plug the other end of the ethernet cable into the sensor. Use the Unit Setup App to connect the sensor to a Wi-Fi network.

Option 3 – PoE+ Injector Using Ethernet

Plug the PoE Injector into any standard 120v wall outlet. Plug one end of a Cat 5e or later ethernet cable into a cradlepoint / router or non PoE switch. Plug the other end of the cable into the Data In port located on the bottom of the Injector. Plug an additional ethernet cable into the Data & Power Out port also located on the bottom of the injector. Plug the other end of the ethernet cable into the sensor.

Networking

Networking Basics

Density devices require internet connectivity to pass data to the web application.
Options to connect your Density devices to the internet:

• Option 1 – Wired internet switch.
• Option 2 – Wi-Fi (requires the Density Unit Setup App to locally set up the device)
• Option 3 – Wired internet via cradle-point.

Networks that are not supported:

• Captive portal

• Proxy

• 5GHz WiFi networks

• WPA2 Enterprise

• Hidden Networks *

• Hidden networks can be used if temporarily made transparent while we configure the devices.

Network Configuration Options

Both DHCP and Static IP configurations are supported. (Static IP configurations require the Density Unit Setup App to locally set up the device).

DHCP Supported Configuration

Option 53 – DHCP Message Type

• Discover

Option 57 – Maximum DHCP Message Size

• 576

Option 55 – Parameter List

• Subnet Mask (1)
• Router (3)
• Interface MTU (26)
• Private/Proxy Auto Discovery (252)
• Network Time Protocol Servers (42)
• Domain Name (15)
• Domain Name Server (6)
• Hostname (12)

Option 60 – Vendor Class Identifier *

• “Density S5 DPU”

Option 61 – Client Identifier

• Mac Address

Option 12 – Hostname

• Density-

Static Configuration Requirements

You will need an IPv4 Address and Name Servers from your IT team to use in the setup process. (Requires the Density Unit Setup App to locally set up the device).

If you have a Corporate Firewall

You will need to whitelist the device MAC addresses (the MAC addresses can be found on the outside of the packaging box for the device). You may also have to whitelist the following addresses to ensure the device is able to communicate to your corporate network:
.density.io
.s3.amazonaws.com
*.pool.ntp.org (if applicable)
connman.net
connectivitycheck.gstatic.com
8.8.8.8 (if applicable)
8.8.4.4 (if applicable)

Density does not currently support IP address whitelisting. A list of exact AP/ subdomains is available by request.
Notes:

• The sensors communicate via https, therefore port 443 must be open.
• ntp port (port 123) must be open.
• If internal DNS is not available then external DNS servers 8.8.8.8 and 8.8.4.4 will be used and port 53 must be open.

Unit Setup App

Used to configure units. iOS and Android application available – Go to mobile.density.io to download.

Mount Plate Installation

Ceiling Mount

• Mount plate
• 4pcs #6 x 25in flat head screws
• 4pcs multi-surface anchors

Materials not included

• Mallet
• Drill
• 3/4in drill bit
• 3/16in drill bit
• 1/Bin drill bit
• Ethernet cable (Cat 5e or later)

Power & Connectivity

All sensors require power over ethernet and internet connectivity.

Ceiling Mount Plate Assembly

The ceiling mount plate can be mounted to solid and hollow ceiling surfaces using the provided screws and anchors.
Remove bag from lower insert in the box that contains mount bracket and screws.
Remove items from the bag including mount plate and screws and anchors.
Position mount bracket on the ceiling in the prescribed location, with one of the square slots pointing in the direction the ethernet jack needs to point.

Step 1: Mark Placement
Using a pencil or pen mark location on ceiling for anchor screws using two screws at a minimum. If using the opening as a cable pass through to the ceiling, outline the opening location on the ceiling.

Step 2: Drill Holes
Drill a hole through each pencil mark using a 3/16in drill bit. For hollow substrates, drill completely through. For solid wall materials, drill holes with a depth of at least 1 1/4in (3.2cm).
For wood or metal, use a 1/8in drill bit to create a pilot hole.
If using the cable pass through slot, use a 3/4in drill bit to create the hole in the ceiling.

Step 3: Insert Anchors
Use a mallet or hammer to tap the anchors into each hole. Anchors should be flush with the wall.

Step 4: Install Mount Plate
Align the holes in the mount plate with the installed anchors. Use a drill with #2 Phillips Screwdriver bit to drive each screw into the drywall anchors. Screws can also be driven in manually with a standard Phillips head screwdriver.

Step 5: Drill Cabling Hole
Drill a hole using a 3/4in (16mm) drill bit to route cable through.

Step 6: Route Cable
Route the ethernet cable through the drilled hole. Make sure the cable passes through opening in mount plate if you’re using the Cable Pass Through.

Step 7: Attach Open Area Sensor
Attach the Open Area unit by threading onto the bracket. Pull the ethernet cable through approximately 6 inches out from the opening in the ceiling.
Screw the unit down all the way until it stops, then back it off to the prescribed location using the ethernet jack as the location guide.

Step 8: Plug in Cable
Plug the ethernet cable into the Open Area sensor. The sensor will automatically power up and the LED indicator on the front of the sensor will turn white.
Ensure the Open Area unit is level and parallel to the floor.
