Step 1

Remove the front lid

Use a flathead screwdriver to release the locking screw and lift off the lid.

Step 2

Remove the detection unit

Release the clips and lift out the detection unit to access the Olarm CONNECT.

Step 3

Add your device & configure zone

Scan the QR code on the Olarm CONNECT to add the device, then configure your zone and detector settings.

Step 4

Insert the batteries

Place the batteries into the Olarm CONNECT. The status LED will flash blue when powered on correctly.

Step 5 (Option A)

Mount the Olarm 90XS directly to the surface

Use this option when mounting directly to a wall or flat surface.

Step 5.1a

Remove the backbox

Separate the backbox from the mounting plate.

‍

Step 5.2a

Secure the mounting plate

Fasten with suitable screws, ensuring the tamper switch is compressed. Use the built-in level for alignment.

‍

Step 5.3a

Reconnect the backbox

Attach the backbox to the mounting plate using the original screws.

Step 5.4a

Re-insert the detection unit

Slide the detection unit and Olarm CONNECT back into the backbox and secure with screws.

‍

Step 5 (Option B)

Mount the Olarm 90XS to a pole

Use this option when wall mounting isn't available.

‍

Step 5.1b

Secure with metal strips

Feed the metal strips through the pole mount slots and tighten to secure.

Step 6

Installing the Olarm 90XS

Step 6.1

Adjust the detection angle

Swivel the detection unit left or right to set your desired coverage angle.

Step 6.2

Adjust the detection distance

Slide the lower lens up or down to set your detection range.

Step 6.3

Close the front lid

Press the lid firmly until it clicks into place to prevent tampering.

Tips

Reduce nuisance alarms

Avoid these common installation mistakes that can trigger false alarms.

Tips

Mounting mistakes to avoid

Mount between 0.8m–1.2m. Avoid mounting too high or too low.

Troubleshooting

LED states

Understand what each LED pattern means on your Olarm 90XS and Olarm CONNECT.

Step 7

Test your detector

Enable Detection Test mode in-app or by opening and closing the cover, then walk through the area to verify coverage. The red and orange LEDs will flash when movement is detected.

Troubleshooting

Why is the Olarm 90XS not turning on?
  • Confirm the batteries are inserted correctly (right way around + seated firmly).
  • Replace with fresh batteries (don't mix old/new).
  • Power-cycle: remove batteries, wait 10 seconds, reinsert.
  • Are you sure it's off? Try enable the LED indicator in the device settings.
Why is the Olarm 90XS not pairing / not showing in the app?
  • Make sure you're in the correct Olarm HUB in the app.
  • Move the detector closer during pairing (a few meters).
  • Power-cycle and try pairing again.
Why is the Olarm 90XS showing as paired but "offline"?
  • Remove the detector from the Olarm HUB and try repairing.
  • Check battery level and replace if unsure.
  • Reduce distance/obstructions to the Olarm HUB.
  • Try relocating the detector slightly (even 30–50cm can improve signal).
Why is the detector not detecting me when I walk past it?
  • Confirm it's mounted at the recommended height for the 90XS.
  • Adjust the sensitivity in the app to your required level.
  • Walk across the detector's view, not directly toward it.
  • Check the LED indicator has been enabled & that you have initiated a Detection test.
Why is the detector detecting me when I'm close, but not when I'm further away?
  • Adjust the sensitivity in the app to your required level.
  • Check the detection range - adjust as required to detect further away.
  • Confirm you're within the detector's rated range.
  • Ensure nothing is blocking the 90° field of detection.
Why is the detector detecting me far away, but not when I'm close to it?
  • It's likely aimed too high - re-aim to cover the near approach.
  • Is the approach on an upward slope? The detector may not be picking you up as you walk down the slope.
  • Re-test by walking across close to the detector.
  • Adjust the sensitivity in the app to your required level.
Why is the detector detecting outside my boundary / into the street?
  • Re-aim so the 90° coverage stays inside the property line.
  • Re-adjust the detection range as per the installation guide for your required distance.
  • Avoid mounting positions that "look" out of the gate toward public areas.
Why am I getting false alarms at night?
  • Check the detection range and angle has been adjusted for the required environment.
  • Avoid aiming at reflective surfaces (windows, glossy doors, wet paving).
  • Check for insects/spider webs near the sensor (especially near bright lights).
Why am I getting false alarms when it's windy?
  • Try keep moving vegetation out of the detection area.
  • Don't mount on thin posts or sheet metal (vibration causes issues).
  • Make sure the detector is screwed down tight and stable.
Why does the detector trigger when the gate/garage door moves?
  • Don't aim the detector across a moving gate/garage door path.
  • Reposition so it monitors the approach path, not the moving object.
Why does the detector trigger when it rains / after rain?
  • Avoid mounting where gutter runoff or water spray crosses the detection area.
  • Check if there are puddle/water catchments after it rains, these may be reflecting into the lens.
Why does it trigger sometimes, but not consistently?
  • Adjust the detection rest period to your required settings. (Change to instant should you require the detector to trigger whenever there is movement.)
  • Adjust the sensitivity in the app to your required level.
  • Slightly adjust aim (small changes make a big difference outdoors).
Why is the detector "too sensitive" in this spot?
  • Adjust the sensitivity in the app to your required level.
  • Re-aim to reduce coverage of high-traffic areas (driveways/paths).
  • Move it away from reflective surfaces and heat sources.
  • Choose a location where people cross the field of view, not approach head-on.
Why is the detector easy to trigger by pets?
  • Re-check mounting height, mount at 1.2m should there be pets present.
  • Adjust placement so the detection area doesn't cover pet walkways.
  • Re-check mounting height and aim to avoid the lowest near-ground area.
