Installation Guide

Olarm ENTRY

For detecting open/close

View Datasheet

Step 1

Remove the front lid

Use a flathead screwdriver to lift, leverage upwards & release the lid.

Step 2

Insert the battery

Insert the the provided CR123A battery to power up the Olarm ENTRY. Ensure the battery orientation matches the symbols enclosure.

Step 3

Add your device

Scan the QR code on the Olarm ENTRY, then configure the zone & detector settings.

Step 3

Installation of Olarm ENTRY

Most doors, windows & entry points open & close differently. The Olarm ENTRY has flexible mounting options. Follow the steps below.
‍

Step 3.1

Alignment markers & max distance

Use the markers engraved on the sides of the enclosures to align both units for optimum detection. Never exceed 15mm distance between the main unit & magnet.

Step 3.2

Main unit to fixed frame

Where possible, ensure the main detection unit is installed on the fixed frame. Alternatively, install on surface that moves less & does not go outside. Install the magnet on the moving frame.

Step 3.3

Orientation examples

See the the visuals below to understand the various positioning and installation orientations.

Step 4

Mount the Olarm ENTRY

Secure the Olarm ENTRY main unit & magnet to their respective surfaces using the mounting hardware provided. Remember that adhesive withers over time and will jeopardise the devices functionality.

Step 5

Close the device

Clip the front lid back onto the main unit & magnet. Ensure both lids of the Olarm ENTRY are clipped securely.

Step 6

Test the open/close behaviour

Actively open/close the entry point to test your device to ensure it is installed adequately. The LED indicator will flash blue when opening/closing is detected.

‍Step 7

LED states

Understand what each LED pattern means on your Olarm ENTRY.

Tips

What to avoid when installing

Avoid mounting mounting; on unstable surfaces, on direct steel contact, in outdoor environments, near strong magnetic sources, using adhesives, near hinges or easy to reach positions.

Tips

Mounting mistakes to avoid

Ensure both units are as parallel with each other as possible, as well as ensure the alignment markers are used. Do not exceed the 15mm distance allowed.

Troubleshooting

Why won't my Olarm ENTRY pair to the Olarm HUB?
  • Scan the QR / enter the serial first so the HUB listens for that specific device.
  • If it fails, move closer to the Olarm HUB, remove the battery, wait a few seconds, reinsert, retry.
Why does the Olarm ENTRY keep dropping offline / showing weak signal?
  • Olarm HALO signal may be poor at the mounting spot (metal frames, dense walls, corners).
  • Check signal strength in the app before final mounting.
  • Relocate the device slightly or adjust HUB placement — small moves can make a big difference.
Why is Olarm ENTRY not detecting open/close reliably?
  • The magnet may be misaligned, too far away, or mounted on a different surface plane.
  • Align the markers and keep the gap under ±15 mm (closer is better).
  • Test multiple open/close cycles before tightening screws.
Why does Olarm ENTRY show "Open" even when the door/window is closed?
  • The magnet may be positioned incorrectly or too far from the main unit.
  • Re-check marker alignment and reduce the gap.
  • Ensure the magnet is on the moving surface and the main unit is on the fixed frame.
Why does Olarm ENTRY show "Closed" even when the door/window is open?
  • The magnet may still be within range when the door opens (sliding doors and small openings).
  • Reposition the magnet so it moves clearly away from the main unit during opening.
  • You may have mounted the Olarm ENTRY on a magnetic surface.
Why is Olarm ENTRY triggering open/close randomly (without the door moving)?
  • The door/frame may be flexing or vibrating (wind, loose frame, garage doors).
  • Tighten mounting, choose a more rigid section of the frame, and avoid "springy" surfaces.
  • Check for magnetic interference (strong magnets, motors, metal distortion close to the device).
Why is the Olarm ENTRY battery draining faster than expected?
  • Busy zones + LED enabled + weak Olarm HALO signal can increase power use.
  • Improve signal strength (relocate slightly / adjust HUB position) and reduce nuisance events.
  • Consider disabling the LED if the site requires it.
