This guide describes how to install and set up O3 Edge multisensor devices. You will need an Android or iOS
device with the Proviso™ app installed. Download the app for free from Google Play or the App Store.
The O3 Setup app is no longer supported. If you are still using the O3 Setup App, you will be directed to install the Proviso app.
Once you have installed the Proviso app, you can then uninstall the O3 Setup App from your iOS or Android.
Installation
Follow all applicable electrical codes and regulations. Connect to a Class 2 power source only.
Wiring guidelines
The O3 Edge requires a 24 VDC power supply and
draws 2 W typical, 10 W max.
• For power and I/O wiring, use 22–14 AWG
2-conductor copper wire.
• For network cabling, use Cat5e or Cat6 cables.
Earth ground all devices in the same circuit at the
power supply. Up to 30 devices can be daisy chained
using the ETH2 port as long as the distance between
the devices does not exceed 100 m (330 ft). A bypass
switch allows the devices to relay data in a power failure scenario.
However, the maximum cable length is reduced by 15 m (50 ft) for each bypassed device.
Placement guidelines
You can mount the O3 to a ceiling tile, finished ceiling, or junction box.
• The device should be mounted 2.4 to 4.6 m (8 to 15 ft) off the floor.
• For best performance, place the device in center of the room. Try to keep it at least 2.1 m (7 ft) away from
windows or exterior walls.
• Choose a location where the motion sensor view is not obstructed by light fixtures, shelves, etc.
• Do not mount the device next to hot or cold sources.
• Keep the device at least 1.3 m (4 ft) away from ceiling diffusers and other sources of airflow.
Mounting the O3
1. If you are mounting directly to the ceiling, cut a hole 32 mm (1¼ in.)
in diameter and pull the wires through the hole.
2. Pull the wires through the hole in the backplate.
3. Mount the backplate to the mounting surface using M4 (#8) screws.
4. Connect the power wires, I/O wiring (if present), and Ethernet cable(s).
5. Attach the O3 to the backplate. Line up the tabs on the O3 with the
notches on the backplate, hold the O3 firmly against the backplate, then
twist clockwise.
6. Turn on power to the O3. The light ring plays a blue swirl pattern, then
displays blue-red-yellow as the device runs a power-on self-test (POST).
The POST status displays next. Green = passed, blue = Bluetooth issue,
red = sensor issue, yellow = network connection issue.
