Automatic Door Safety Sensors NZ: What Installers Must Check
Essential Security Supplies
Before handing over an automatic pedestrian door in New Zealand, installers should verify four essentials: activation and presence-detection zones protect the relevant approach and hazard areas; the door operator responds correctly to safety and monitored fault inputs; walk-tests cover the closing edge, threshold, slow-moving and stationary users; and the commissioning record identifies the applicable manufacturer instructions, performance standard and any building compliance-schedule requirements. This installer guide covers both swing and sliding doors. Use the approved design, current manufacturer test method and a site-specific risk assessment rather than treating a sensor as a stand-alone compliance certificate.
Start with the door type, users and hazardous zones
Record whether the opening is a swing or sliding door, its pedestrian traffic, opening and closing direction, glazing and adjacent side screens. Identify the main closing edge, hinge-side or secondary crushing points, threshold, and any accessible recess. Mark the required approach/activation zone separately from safety-presence coverage on a site drawing. A door that opens reliably when somebody approaches may still have an unprotected closing or sweep zone.
Distinguish activation from presence safety
An activation sensor sends an opening request; a presence safety sensor monitors the people or objects that could be struck, trapped or crushed during movement. Some combined radar/infrared units offer both functions, but the installer must confirm the specific functions and test each zone independently. Verify what the operator does when a safety input is active or a monitored sensor reports a fault. See our automatic door retrofit guide for why activation and protection must be specified together.
Map the full hazardous movement
Check the sweep or slide path, closing edge, pinch points, recesses and adjacent fixed objects. Consider users who pause, turn back, approach from unusual directions or use mobility aids. The correct coverage depends on the door design and site.
Site decision: Record the person responsible for this check, the model or drawing used, the acceptance condition and any unresolved limitation. If a component is being retained from the existing installation, compare the new manufacturer requirements with its measured condition before approving reuse.
Mount devices according to their listing
Use manufacturer instructions for mounting height, angle, field size and required controller connections. Sunlight, reflective flooring, glazing and moving objects can change sensing behaviour. Verify environmental suitability rather than assuming all radar and infrared sensors behave alike.
Coordinate all control modes
Test day, night, locked, manual and emergency operation as applicable. Make sure the operator treats safety inputs correctly in each mode. A sensor may work in a normal demonstration yet be disabled or configured differently in another mode.
Walk-test activation, presence and fault responses
Use the test object or test body and movement sequence prescribed by the exact sensor manufacturer and applicable performance standard. Do not rely on a hand-wave demonstration. Test with representative standing, slow-moving and returning pedestrians, pushchairs and wheelchair users where relevant. Confirm presence hold time and operator timing against the approved settings; retest after any adjustment to sensitivity, door speed, sensor angle or surrounding flooring.
| Zone or input | Test | Expected result and pass evidence |
|---|---|---|
| Approach activation | Approach at normal and slow speed from intended directions | Door opens before the user reaches the moving leaf; document the actual activation boundary |
| Main closing edge and threshold | Place the specified test body in the closing-path detection area | Door does not close dangerously on the test body; record operator response and sensor setting |
| Stationary presence | Hold the specified test body motionless in the protected area | Safety detection is maintained for the configured interval required by the applicable test method |
| Hinge-side/sweep and side screen | Test each accessible crushing zone on a swing door or adjacent side-screen area on a sliding door | Required protection is demonstrated or a documented approved alternative is in place |
| Monitored safety fault | Use the manufacturer-approved fault simulation method | Operator enters the specified safe response and indicates or records the fault where required |
Record pass/fail, test date, technician, test body/method, controller mode and corrective action. The exact acceptable response depends on the operator design and manufacturer instructions.
Swing versus sliding door sensor layout
On swing doors, assess the leaf sweep, leading edge and hinge-side hazard, including both faces where people can approach or remain within the movement area. Confirm leaf-mounted versus frame-mounted sensor compatibility, door width, cable routing and the operator control input. On sliding doors, check header-mounted presence/activation coverage at the threshold and moving closing edges; examine fixed side screens and recesses that a sliding leaf could move alongside. Sensor positioning and protection on either design depend on the applicable risk assessment, manufacturer instructions and performance standard, not simply the number of sensors fitted.
NZ compliance schedules, fire escape and accessibility
Automatic doors within the defined scope may be listed as specified system SS 3/1 on the building compliance schedule. Relevant performance standards can include NZS 4239:1993, AS 4085:1992 and AS 5007:2007; confirm the specific standard and edition recorded for the building rather than treating all three as interchangeable. Inspection frequencies and responsibilities must follow that building’s compliance schedule: owner/agent checks may be more frequent, while an independent qualified person (IQP) may undertake the required annual inspection and issue Form 12A documentation. Keep inspection and maintenance evidence and the required two-year records. Check fail-safe or breakout operation, power failure and fire-alarm interfaces, and confirm the escape-route operation cannot prevent safe exit. See MBIE inspection and maintenance guidance and Dunedin City Council’s SS 3/1 guidance. Our swing versus sliding door guide discusses the broader door selection and escape-route considerations.
Document maintenance and retest triggers
Keep sensor model, configuration, wiring, test evidence and maintenance instructions. Require retesting after flooring changes, glazing alterations, operator replacement or a reported near miss.
Planning, procurement and handover
Write the specification brief
For a New Zealand project, separate confirmed facts from design decisions. Record site identity, operating hours, users, interfaces, exposure conditions, drawings available and the named person who approves the operating sequence. The most expensive later changes often arise from an assumption that was not stated in the brief. The specification should describe the outcome needed while leaving product performance to verified technical documents. A sensible handover starts with a one-page requirement register listing each decision, the approving stakeholder, the evidence needed and the commissioning test that will prove it.
What to request from a supplier
Request the current installation instructions, the exact model and part number, dimensional drawings, controller and power requirements, accessories, firmware or software dependencies where relevant, and maintenance documentation. Confirm which items are supplied and which are separate trades. Ask for written clarification of uncertain compatibility rather than relying on a product photograph or shorthand range name. This matters especially when a project combines equipment from several manufacturers or contains legacy infrastructure that no longer matches the current catalogue.
Coordinate trades and responsibilities
Agree which contractor owns civils, electrical supply, access-control programming, network changes, mechanical work, safety risk assessment and the final integrated test. Record physical and electrical boundaries between packages. If a design cannot be signed off because a model is not yet selected, mark that dependency as open rather than allowing installation to proceed on assumed dimensions. This discipline helps avoid rework and makes handover defects easier to trace to the responsible scope.
Common mistakes to avoid
Do not order hardware before surveying the actual opening or site. Do not substitute an attractive specification from a neighbouring model. Do not accept a demonstration that tests only the happy path. Do not omit practical service access, weather exposure, emergency operation or an alternative procedure when a controller fails. Most importantly, do not treat a functioning component as proof that the entire integrated system works safely and as intended.
Record the handover evidence
The handover pack should identify installed models, serial numbers where useful, firmware versions where relevant, as-built cabling and layout, user roles, maintenance instructions and supplier contacts. Include photographs of concealed work before finishes are closed and a schedule of tests with actual results. Record defects and agreed follow-up actions separately from accepted functions. A dated sign-off protects the installer and gives the operator a workable reference for future maintenance and changes.
Commissioning checklist for the installer
- Identify the exact installed model, its documentation and operating configuration.
- Photograph and check the site conditions against the approved drawings.
- Verify power, wiring, mechanical fixings and environmental protection as applicable.
- Test routine operation with representative standing, slow-moving, pushchair and wheelchair users as relevant to the site.
- Test rejected or unusual inputs, loss of power and relevant emergency functions.
- Confirm fault reporting, operator response, maintenance access and as-built records.
- Record the responsible person and retest any faults before final sign-off.

Frequently asked questions
What standards apply to automatic door safety sensors in New Zealand?
Check the performance standard specified for the actual installation and compliance schedule. Depending on the door and building, referenced standards may include NZS 4239:1993, AS 4085:1992 or AS 5007:2007, alongside the manufacturer’s instructions.
Do swing doors need safety sensors on both sides?
The layout depends on where people can approach or remain within the leaf sweep and other hazardous areas. Assess each accessible face, leading edge and hinge-side hazard, then follow the applicable standard and the operator and sensor manufacturers’ approved arrangements.
How often must automatic door sensors be inspected?
Follow the building’s compliance schedule and the applicable manufacturer recommendations. The schedule can assign frequent owner or agent checks and periodic IQP inspections; the IQP provides Form 12A certification when required.
Can one sensor provide activation and presence safety?
Some combined sensors can, but not every model or configuration does. Verify the declared functions, detection fields, monitored input compatibility and responses separately using the current manufacturer commissioning procedure.
