Alarms in Sturry
Smoke and heat alarm installation in Sturry — mains-wired interlinked systems for landlords and homeowners across Canterbury.
Mains-wired interlinked smoke and heat alarm installation in Sturry — for landlords meeting smoke alarm regulations on rented homes and HMOs, homeowners upgrading from old battery-only alarms, and anyone fitting out a new kitchen who needs a heat alarm added. CJA Electrical is an Aico Expert Installer fitting Aico 3000 Series across Canterbury, with the install signed off to BS 5839-6.
What Alarms actually is
A modern domestic smoke alarm system has three component types: smoke alarms (in circulation spaces — landings, hallways), heat alarms (in kitchens where smoke alarms would false-trigger), and carbon monoxide alarms (where there’s a fixed combustion appliance — boiler, gas fire, wood burner). All three are wired to mains supply with battery backup, and all three interlink so that one going off triggers them all. The system runs on Grade D1 power supply (mains plus sealed rechargeable battery backup) for most Sturry domestic property, with grades stepped up for HMOs and larger installations depending on the BS 5839-6 risk assessment.
When you need Alarms in Sturry
The triggers for new alarm installation work in Sturry: a rented property compliance check (the 2022 amendment regs require minimum coverage), an HMO licence application or renewal (council typically specifies a higher BS 5839-6 grade), a sale or purchase where the surveyor flags inadequate smoke detection, a kitchen renovation needing a heat alarm, or simply a homeowner deciding it’s time to retire the 1990s battery-only alarms. For new-build property the original installer will have fitted the system, but those alarms reach end-of-life around 8-10 years in (battery-backed Grade D1) and need replacement on a similar cycle. We swap end-of-life alarms on a like-for-like basis where the existing layout and grading is sound.

Standards and what compliance looks like
The technical standard for domestic smoke alarms in the UK is BS 5839-6 — “Code of practice for the design, installation, commissioning and maintenance of fire detection and fire alarm systems in domestic premises”. The standard sets out grades (A, B, C, D1, D2, F) covering different supply configurations and protection levels, with Grade D1 (mains + sealed 10-year battery, interlinked) the standard for most Sturry domestic property. For HMO common parts, the standard typically steps up to Grade A (panel-based) or Grade B depending on the building size and complexity. Canterbury City Council will specify the required grade as part of the HMO licence conditions.
Fittings and where they go
Where each alarm goes on a Sturry domestic install: Smoke alarms — circulation spaces. Landings, hallways, top and bottom of stairs. Mounted to the ceiling at least 300 mm from any wall or light fitting. Heat alarms — kitchens. Mounted to the ceiling, away from the cooker hood, where rising heat would reach the alarm promptly without interference from steam or oil vapour. CO alarms — mounted near (not directly over) any fixed combustion appliance: boiler, gas fire, wood burner. Manufacturer guidance specifies horizontal and vertical distances; we follow the Aico install guide on each fitting. Multi-sensor alarms (combined smoke + heat) are an option in some scenarios — useful in open-plan kitchen-diner layouts where a pure smoke alarm would false-trigger on cooking.

Testing schedule and remedials
The maintenance side of any installed alarm system splits into householder testing (monthly button-press, takes 30 seconds per alarm) and competent-person servicing (annual, confirms the system is operating to BS 5839-6 spec). For Sturry property, both are achievable easily — we leave instructions and a logbook with the householder so the monthly tests are recorded, and we’ll come back annually for the formal service if asked. For HMO and rental properties, the testing logbook specifically matters — fire risk assessors and council inspectors will check it during HMO licence renewals or enforcement visits. Properly recorded test events demonstrate the duty-holder is meeting their obligations.
Why Sturry property owners book CJA Electrical
What sets Aico Expert Installer apart on a Sturry smoke alarm install: the install is done to manufacturer specification rather than generic best-practice; the layout follows Aico’s Risk Assessment Tool which couples cleanly to BS 5839-6; Aico back the install with extended warranty when it’s done by an Expert Installer; and the customer gets a system they can trust to perform when needed. Practically, that means we know the kit, we know where each alarm type goes, and we know how to commission the interlink so it actually works. Plus a full BS 5839-6 certificate at the end documenting the install for insurance, council, and fire risk assessor purposes.
How the work runs
Step one — site visit to assess the layout and pick the right grade. We walk the property, identify circulation spaces, kitchens, and any rooms with fixed combustion appliances. For most Sturry domestic property the spec is straightforward Grade D1; HMOs and larger conversions get a more detailed risk assessment. Step two — quote. Fixed-price for most domestic installs, sent through within a working day. The quote covers the alarms, interlinking method, install labour, and the BS 5839-6 certificate at the end. Step three — install. Single visit for most Sturry domestic work, half a day on site. We install each alarm, commission the interlink, demonstrate the test procedure, and leave the BS 5839-6 certificate plus a logbook with the householder.
What affects the price
The factors that move Sturry smoke alarm install pricing: number of floors and circulation spaces (more alarms), interlinking method (RF and hard-wired land at similar price points but RF is typically faster on retrofit), any consumer unit work needed (adding a dedicated alarm circuit), and any rewiring required where existing alarm wiring isn’t viable. Quote includes everything: the alarms, interlinking, labour, consumer unit work if needed, demonstration, and the BS 5839-6 certificate. No hidden costs, no surprise add-ons on the day.
FAQs
How long do mains-wired alarms last?
Aico 3000 Series alarms are designed for a 10-year service life with sealed batteries that last the same period. The alarm itself signals end-of-life via its status indicator a few months before expiry, giving plenty of warning to schedule replacement. Older alarms (pre-3000 Series) often have shorter lives, particularly fluorescent bulkhead-style units which were typically rated for 8-10 years.
Can you install in occupied property without making a mess?
Yes. Most Sturry domestic installs run as a single-visit half-day job with minimal disruption. Wireless interlinking means no need to chase wires through walls between alarms; the install is mostly about mounting alarms to ceilings and connecting each to a power supply. Dust sheets out, vacuum on the way out.
What’s the difference between heat and smoke alarms?
Smoke alarms detect smoke particles in the air and trigger on combustion. Heat alarms detect temperature rise (typically triggering at 58°C or more) and don’t false-trigger on cooking smoke or steam. Heat alarms go in kitchens; smoke alarms go everywhere else. Multi-sensor alarms combine both and are useful in open-plan kitchen-diner layouts.
Do I need a CO alarm too?
If the property has any fixed combustion appliance — gas boiler, gas fire, wood burner, oil boiler — yes. The Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022 require a CO alarm in any room used as living accommodation where there’s a fixed combustion appliance. We fit Aico Ei3018 CO alarms as part of the same install, interlinked with the smoke alarms.
What documentation do I get after the install?
A BS 5839-6 certificate documenting the install — alarm types, locations, interlink method, supply, and the commissioning test result. Plus a logbook for ongoing monthly test records that stays at the property. The certificate is what fire risk assessors, councils, insurers, and (for landlord property) tenants will expect to see.
