Electric Strike Installation in Perth: Complete 2026 Guide
The intercom is installed, the keypad lights up, and the property owner can see the visitor at the front gate. But pressing the release button produces only a click from the control panel. The latch stays engaged, the door remains shut, and everyone starts blaming the reader, the wiring, or the new access-control system.
Often, the problem is at the door frame. An electric strike has to match the latch, frame, door alignment, power arrangement, fire-door requirements, and Western Australian licensing rules. A neat-looking strike that sits under tension can become a recurring service call, while the wrong fail mode can create a serious safety or compliance issue.
What an Electric Strike Actually Does
An electric strike takes the place of, or works alongside, the fixed strike plate fitted into a door jamb. The door's latchbolt enters the strike keeper when the door closes. When the access-control system grants permission, the strike releases that keeper for the required operating period, allowing the latchbolt to pass while the user pushes or pulls the door.
That's why an intercom, keypad, or card reader can't open a door by itself. The reader makes the decision, the controller sends the release signal, and the strike performs the mechanical work at the frame. A compatible low-voltage power supply and correctly selected strike complete the chain.
The distinction from a magnetic lock matters. A magnetic lock holds the door closed with magnetic force, usually across the door and frame, while an electric strike works with the door's existing latch and handle set. A strike can therefore preserve a familiar lever operation from inside, but it depends much more heavily on latch engagement, frame preparation, door sag, and the pressure placed on the keeper.
Manufacturers commonly offer strikes for 12 V DC or 24 V DC systems, but the exact operating requirements belong to the selected product, not to a generic wiring assumption. Australian product families include monitored and unmonitored versions, models for Australian door profiles, and fire-rated options. Some published products carry performance claims such as 4-hour fire ratings, but that rating applies only when the listed product, door assembly, installation, and use conditions are appropriate, as described in Australian electric strike product guidance.
Practical rule: The reader decides who may enter. The strike decides whether the door can physically release. Both have to be specified as one system.
For commercial projects, the electrical take-off also needs to account for the strike, controller, cabling, protection components, and power supply. A specialist estimating resource such as Exayard electrical estimating software can help organise that scope before installation begins. For homeowners choosing a video entry system, the relationship between the intercom and the release hardware is outlined in this video intercom system with door release guide.
Choosing the Right Strike for Your Door
The correct strike starts with the door, not the access reader. A timber residential door, aluminium shopfront, steel-framed commercial opening, and fire-rated door each impose different limits on the strike body, faceplate, keeper, wiring path, and release behaviour. In Perth, the opening's use and the applicable compliance requirements should be settled before choosing a model.
Fail mode comes before convenience
A fail-secure strike remains locked when power is removed, subject to the door hardware and approved mechanical egress arrangement. It suits an entry where security during a power outage has priority, provided occupants can still leave safely through the required internal release method.
A fail-safe or power-to-open arrangement releases when power is removed. That may support access during an outage or an emergency release condition, but security changes whenever the power circuit is unavailable. Choose the mode against the door's egress and fire requirements, rather than treating either option as universally safer.
Australian fire-door guidance treats electric strikes as secondary locking devices only. They cannot become the primary locking device on a fire door. The power configuration, supplied hardware, wire size, alignment, and complete door-hardware combination need checking before commissioning, as set out in the Lockwood electric strike building-product sheet.
Monitoring and frame compatibility
A monitored strike includes contacts that report door or keeper status to the access panel. That helps an operator distinguish a normal access event from a forced or held-open condition. An unmonitored strike is simpler, but the controller receives less information about the opening.
The faceplate and strike body must suit the jamb. Compare the manufacturer's template with the existing frame before cutting. A strike designed for a steel jamb may not seat in a narrow aluminium profile, while a deep body may have no room behind a thin timber stop. The keeper also needs clean latch engagement, with roughly 1 mm of clearance where the selected product and door arrangement call for it. Check for back pressure before final fixing. A door that pushes hard against the keeper can make a correctly wired strike unreliable.
| Strike Type | Fail Mode | Best Suited To | Watch Out For |
|---|---|---|---|
| Standard unmonitored strike | Fail-secure or fail-safe, according to model | Straightforward residential or internal access | The controller may not know whether the door released |
| Monitored strike | Either available configuration, according to model | Commercial doors needing status feedback | Extra contacts need correct termination and testing |
| Fire-rated listed strike | Must match the approved door assembly and required release behaviour | Applicable fire-door openings | It's secondary locking only, and the complete assembly requires verification |
| Aluminium or narrow-profile strike | Model-specific | Aluminium shopfronts and restricted jambs | A standard body can foul the frame or leave poor latch engagement |
| Heavy-duty steel or timber-frame strike | Model-specific | Commercial entry doors and heavy-timber frames | The jamb may need substantial preparation and protected cable routing |
A magnetic lock may suit a door with no usable latch interface or a design requiring surface-mounted hardware. It brings separate egress and monitoring requirements, so assess the door, users, emergency release path, and the magnetic lock system as one design. Fire doors, exit routes, and regulated electrical work should be referred to the appropriate licensed tradesperson. A handy person can often handle careful measurement and template marking, but cutting, wiring, and commissioning may require licensed installation and electrical sign-off in WA.
Site Assessment Before Installation Day
A strike can release correctly on the bench and still fail on the installed door. Check the swing, closing action, and latch engagement first. If the door does not return squarely into the frame, pressure against the keeper can cause binding, intermittent release, and premature wear.
Inspect the opening
Record these details before ordering hardware:
- Door and frame material: Identify timber, steel, aluminium, or a composite arrangement. The substrate determines the cutting method, fixing choice, available cavity, and whether a backbox or reinforcement is needed.
- Latch and backset: Measure the latchbolt position, faceplate shape, projection, and relationship to the jamb. The keeper must receive the latch cleanly without forcing the handle or door.
- Frame depth: Confirm that the strike body can sit fully inside the jamb. A faceplate may look suitable from the front while the body bottoms out behind the frame.
- Closing alignment: Check hinges, seals, dropped doors, warped stiles, and latch engagement. Correct the door if the latch arrives high, low, or at an angle.
- Existing services: Look for concealed wiring, reinforcement, glazing channels, and any backbox behind the proposed cutout.
Measure the mechanical condition before deciding on a model. A strike cannot compensate for a sagging door, an incorrectly set closer, or a latch that remains under pressure when the door is closed.
A property manager should establish whether the opening forms part of a fire-rated separation, an exit route, a stair enclosure, or a controlled area. The WA access-control policy requires agencies to protect physical access to assets and control entry and exit, with controlled areas using measures such as locks, proximity readers, or biometric identification. The door and frame therefore form part of the security design, not just the carpentry work. Fire-door alterations and regulated electrical work should be referred to the appropriate licensed tradesperson.
Plan the cable and power location
Trace the low-voltage route from the strike to the access controller or power supply. Keep the cable clear of sharp metal, moving hinges, door closers, and the strike body. On a commercial site, confirm who controls the equipment location, how the power supply will be isolated and serviced, and whether the system has suitable backup arrangements.
A handy person can usually measure the opening, inspect clearances, and mark the template. Cutting a fire-rated door, wiring fixed electrical equipment, or commissioning access control may require licensed trades and electrical sign-off in WA.
Do not quote the job from the reader position alone. Inspect the frame, cable route, latch, closer, egress hardware, and power equipment before selecting the strike.
Tools, Materials, and the Actual Installation Sequence
The basic kit usually includes the selected electric strike, manufacturer template, drill, metal or timber preparation tools, screwdrivers, file, measuring tools, low-voltage cable, suitable fixings, and a multimeter. The control side may require an access controller or intercom relay, a compatible power supply, and a diode or MOV for the inductive strike load where specified by the equipment manufacturer.
Frame preparation
Start by marking the latchbolt centreline on the jamb. Apply the supplied template with the door closed and latched, then confirm that the faceplate position matches the latch faceplate and the strike body has room behind the jamb.
Prepare the opening for the actual substrate. Timber can require controlled chiselling or routing, while steel and aluminium need careful cutting, filing, and protection of the frame finish. Don't enlarge the recess to make an incompatible strike fit. If the body or faceplate doesn't match the opening, stop and confirm the model, profile, and template.
The installation guidance for Australian Lockwood electric strikes calls for approximately 1 mm of clearance between the latch and keeper, so the closed door doesn't press the latch hard against the release mechanism. That small clearance is not cosmetic. It prevents back-pressure, latch drag, and an intermittent release.
Cable routing and temporary fit
Route the cable away from sharp edges and moving parts. Use protection where the conductor passes through metal, leave enough service length for the strike connection, and keep the cable path separate from anything that could crush or abrade it.
Temporarily fit the strike before tightening every fixing. Close the door gently, observe the latch entering the keeper, and check whether the door or seal pushes against the strike. Operate the release with the door pressure removed, then repeat while applying the normal closing pressure.
Alignment check: A strike that releases with the door open has not passed the test. It must release with the door closed, latched, and free from damaging back-pressure.
Mounting and electrical connection
Once the mechanical fit is correct, secure the strike with the supplied or frame-appropriate fixings. Make the electrical connections from the manufacturer's diagram, confirm polarity where relevant, and fit the specified suppression component across the coil if the controller or strike documentation calls for one.
Use the multimeter to confirm the expected voltage at the strike under load, not just at the power supply terminals. Check that the relay switches as intended and that the access-control device produces a clean release rather than a weak, chattering, or delayed operation.
The practical sequence is illustrated in this electric strike installation video.
Finish by checking the faceplate sits flush, the latch enters without scraping, and the door closes and relatches consistently. Record the strike model, fail mode, power arrangement, wiring, and test results for future servicing.
Compliance and Safety in Western Australia
Three responsibilities overlap on a typical Perth opening, but they aren't the same responsibility. Security licensing, fire-door compliance, and electrical authorisation must be coordinated rather than treated as one generic installation task.
WA security licensing
In Western Australia, a person who consults on, installs, repairs, or maintains security alarm systems, security CCTV, or electronic locks must hold a security licence and work for a business holding a Security Agent's licence. The framework operates under the Security and Related Activities (Control) Act 1996 and Regulations 1997, as outlined by the Security Association of Western Australia licensing requirements.
An electric strike connected to access control, an intercom release, electronic locking, or a related security system therefore sits inside a regulated security-services environment. A handy person may be able to carry out ordinary non-security building tasks, such as making a basic timber repair, but that doesn't authorise them to install the controlled locking system itself.
That distinction matters to homeowners, builders, strata managers, and commercial landlords. Ask which licensed business is responsible for the security work, who will issue the installation records, and who will maintain the system after handover. The broader context of Australian security requirements is discussed in this Australian standards security guide.
Fire doors and egress
A fire-rated opening needs more than a strike carrying a fire-related product description. Australian building-product guidance states that electric strikes must not be used as the primary locking device on a fire door. The selected strike must be treated as secondary locking, and the installer must verify the fail mode, wiring, supplied hardware, door alignment, and complete listed combination before commissioning.
The practical question is not only, “Will the door open during a power failure?” It's also, “Will the door remain positively latched and preserve the required fire-door function?” The answer depends on the opening, hardware, egress arrangement, fire listing, and applicable approval conditions.
Electrical sign-off
Low-voltage strike wiring still connects to a powered control system. Australian electrical guidance says electrical installation work must be authorised by the responsible electrical contractor or employer after consultation with the person controlling the premises. The same guidance emphasises safe access controls and barriers around electrical apparatus.
On a mixed-use or commercial project, the security installer should coordinate with the electrical contractor and the building representative. The security technician can specify and connect the access-control components within their authorised scope, while the responsible electrical party handles the electrical work and sign-off that applies to the powered equipment and premises.
Testing, Adjustment, and Common Failures
A strike that clicks but won't release the door usually has a mechanical or power problem, not a mysterious software fault. Test the opening as a complete system, with the door closed and the latch under the same conditions it will experience during daily use.
The supplied test graphic shows a concise routine. In practice, cycle the strike repeatedly through the access device, verify clean release and relocking, check the mechanical override, confirm the selected fail behaviour during power loss, and review any monitored status at the access panel.
Read the symptom before changing parts
Back-pressure is the first suspect when the strike releases with the door open but fails when the door is shut. A tight seal, misadjusted closer, sagging hinge side, or latch pressing against the keeper can hold the mechanism under load. Adjust the door or strike position and restore the intended clearance rather than increasing power blindly.
Keeper interference produces scraping, partial release, or a latch that catches at one point in the door swing. Look at the latch centreline, faceplate seating, and the relationship between the latch faceplate and keeper. A file may remove a small burr, but it won't correct a strike installed at the wrong height or angle.
A click proves the coil moved. It doesn't prove the latch had room to escape.
An undersized or overloaded power supply often causes weak, inconsistent, or delayed operation, particularly when the same supply also feeds readers, intercom equipment, locks, and other loads. Measure voltage at the strike while it operates. If the voltage falls under load, review the supply capacity, cable length, conductor size, relay path, and simultaneous loads with the responsible installer.
A missing suppression component can expose relay contacts and control electronics to the electrical behaviour of an inductive strike coil. If the manufacturer specifies a diode or MOV and it hasn't been fitted, correct that before replacing the controller. Use the component type and connection direction specified for the system.
The wrong fail mode becomes obvious during an outage or emergency test. A door that stays locked when the design requires release, or releases when the opening must remain secured and latched, needs a specification review. Don't solve a classification problem by changing two wires.
When a Professional Securitec Install Makes Sense
A single residential opening with an accessible timber jamb can be a reasonable project for a capable owner-builder who understands low-voltage work, can read the strike template, has a multimeter, and is prepared to correct the door alignment before cutting. The owner still needs to select the correct product, protect the cable, confirm the fail mode, and test the finished opening properly.
Professional installation makes more sense when the opening is fire-rated, part of a commercial egress route, connected to an intercom or access-control network, managed by strata, or repeated across several doors. Those jobs involve more than fitting a faceplate. They require coordinated hardware selection, accurate frame preparation, controlled wiring, system testing, records, and a clear division of responsibility between security and electrical trades.
| Consideration | Self-install | Licensed professional installation |
|---|---|---|
| Time on tools | Depends on door condition and skill | Planned around the opening and system scope |
| Specialist equipment | Basic tools may be enough for a simple jamb | May include templates, frame-preparation tools, and low-voltage test equipment |
| Compliance records | Owner must understand what applies | Licensed business can document its security work |
| Warranty position | Product and workmanship responsibility can be separate | Installation responsibility is clearer |
| Cost of mistakes | Recut frames, damaged hardware, and repeat troubleshooting | Upfront service cost supports correct specification and testing |
Securitec Security is one licensed Perth option for owners who need electric strikes integrated with access control, alarms, CCTV, or intercoms. A separate gate specialist may be more suitable when the fault involves the gate operator, hinges, or automation rather than the strike itself, such as emergency gate repair by Lighthouse Energy Services.
