Installation guide & product manual
Battery-free wireless opening detection for compatible outward-opening, inward-opening, tilt-and-turn and top-hung windows.
Understand the intended installation geometry before preparing the frame.
The Window Sensor monitors the opening state of a compatible window without a replaceable sensor battery. When the protected window moves from closed to open, the triangular actuator state changes and the opening action provides the electrical pulse used to transmit a 433 MHz event to a compatible Apeiron Guard alarm hub.
The alarm hub can then sound a local alarm and pass the opening event into the Apeiron Guard app workflow.
This guide covers the approved fixed-frame installation: mount the sensor vertically at the lower handle-side corner, with the triangular actuator facing downward to reduce the risk of rainwater entering when an outward-opening window is open.
The Window Sensor can support outward-opening, inward-opening, tilt-and-turn and top-hung windows when the approved mounting and actuator requirements can be met. For sliding windows, use the Apeiron Guard Door Sensor where the Window Sensor geometry is unsuitable.
Confirm the approved package contents and prepare the required installation materials.
The sensor is part of a security system; it does not replace physical locks or life-safety devices.
The supplied dimension diagram is the exact visual source for product geometry and scale.
Approved six-step sequence for the standard fixed-frame Window Sensor installation.
Hold the Window Sensor vertically at the lower handle-side fixed stile. The triangular actuator must face downward toward the bottom rail/contact surface to reduce the risk of rainwater entering when the window is open.
With the sensor temporarily held in position, close the window and confirm the bottom contact surface presses the triangular actuator fully inwards. Open the window and confirm the actuator releases freely.
Clean the mounting surfaces using a lint-free cloth and a cleaner approved for the window-frame finish. Remove dust, oil and moisture, then allow the area to dry completely.
Remove the approved adhesive liner without touching the bonding surface. Align the thin L-shaped base with the marked position and keep the sensor vertical with its triangular actuator downward.
Apply firm, even pressure over the mounting base and sensor body without pressing the triangular actuator sideways. Close the window and confirm the contact surface presses the actuator fully inwards.
Close the window fully, arm or place the system in its approved test mode, then open the window and confirm the opening event reaches the hub and app.
Use the selected receiver guide, then verify the complete alarm path.
Follow the receiver-specific guide for enrollment, zone naming, success indications and removal.
Do not permanently hand over the installation until the event is received reliably from the final mounting position.
Use these states to verify both the physical sensor and the connected-system response.
| State | Window Sensor | Expected system behavior |
|---|---|---|
| Window opened | The contact surface moves away and the triangular actuator releases. | The opening action generates/transmits a 433 MHz event to the compatible hub. |
| Window reclosed | The triangular actuator is pressed inward again. | The closing action generates and transmits a second 433 MHz RF event. |
| Armed while open | The sensor remains in the open state when the zone is armed. | Reclosing the window transmits an event and triggers the alarm for the armed zone. |
| Mini Alarm Hub and app | No local control is required at the sensor. | The app shows the real-time open or closed state whether the system is armed or disarmed. |
| Wireless I/O Module | Each opening or closing action transmits an event. | The module response follows the configured integration and zone rules. |
Resolve installation and communication faults before replacing the product.
| Symptom | Likely cause | Action |
|---|---|---|
| No event when opened | Sensor not enrolled, hub unavailable, actuator obstructed, or window movement does not fully release the actuator. | Test near the hub, confirm enrollment, inspect actuator movement and reposition if required. |
| Window appears open when closed | The triangular actuator is not fully pressed inwards. | Recheck vertical alignment and contact height. Remount using approved replacement adhesive. |
| Intermittent alerts | Final location has weak radio conditions, metal shielding or excessive distance. | Test repeatedly at the final position and consider hub relocation or system-design adjustment. |
| Button does not move freely | Dirt, adhesive, paint, frame collision or sideways mounting pressure. | Remove the obstruction. Do not lubricate or open the enclosure. Replace the product if mechanically damaged. |
| Adhesive begins lifting | Contaminated/unsuitable surface, insufficient pressure, premature loading or incorrect replacement tape. | Remove safely, clean the surface and remount with the approved adhesive system. Never reuse removed tape. |
| Wrong device shown in app | Incorrect zone/device naming during commissioning. | Correct the device name and repeat the complete open/close test before handover. |
