Quick answer
Neither wired nor wireless is the best choice for every property. Existing cable condition, access for new wiring, supported equipment, detector positions and ongoing maintenance decide the sensible option. Assess the property and the alarm together before buying a replacement.
A wired alarm and a wireless alarm can look similar to the person setting them each day. The main installation difference is how the devices communicate and receive power. That affects cable routes, batteries, maintenance and whether useful parts of an existing system can be retained.
When wired equipment may make sense
A renovation or new build can provide access for cable routes before finishes are complete. Existing alarm wiring may also be useful, but its presence does not prove it is sound or compatible with a replacement panel and detectors. The cable condition, routes and equipment requirements need checking before reuse is agreed.
EDD considers wired alarm work only where the equipment and installation are within its supported scope. This is established before quoting, rather than treating every legacy alarm as a system that can automatically be adopted.
When wireless can be proportionate
Wireless detectors can reduce the need to run new signal cables through decorated rooms. That can make them useful for careful retrofit or a property where the required cable route is disruptive. They still need suitable fixing positions, an appropriate radio path and the power or batteries specified by the manufacturer.
Wireless is not the same as maintenance-free. The handover should explain battery warnings, replacement arrangements and supported fault indications. The control equipment and sounders may have different power requirements from the individual detectors.
Compare the complete installation
Detector layout matters more than the label
Door and window contacts, PIR or other supported motion detectors and sounders should follow the intended use of the property. Think about entrances, circulation routes, occupied areas and everyday routines. Pets, heat sources and the room environment may affect equipment selection and positioning.
Agree the setting modes, entry and exit sequence and which areas are included in each mode. A simple system the household or staff understand is more useful than a feature list nobody feels confident operating.
Check what app access actually provides
App control and alerts are features of the chosen system, not a guarantee that every wired or wireless alarm supports them. Ask about compatible phones, account ownership, connection dependencies, subscriptions and what happens if the internet is unavailable.
A notification on your phone is different from a professionally monitored service. Do not assume an app includes ARC monitoring, police response or acceptance by an insurer. EDD's current intruder-alarm offer does not advertise those services or unverified security accreditation.
Replacing or taking over an existing alarm
Record the make, model, visible fault and available paperwork. Establish who owns the system and who has authorised access to it. Some equipment can be supported or partly upgraded; other systems may lack compatible parts, usable wiring or recoverable account access. Avoid resets or disconnections before an assessment, particularly if they could leave the property without the intended protection.
What a useful handover should cover
- How to set and unset the agreed modes.
- Which detectors and zones are included.
- What supported fault and battery indications mean.
- Who controls user and app access.
- What servicing is agreed and who to contact for a fault.
