Aico 3000 Series smoke and heat alarms ready for installation

Smoke alarms save lives — but only if they’re sited correctly, interlinked properly, and powered from somewhere reliable. CJA Electrical fits Aico mains-wired interlinked alarms across Gillingham as an Aico Expert Installer (manufacturer-trained on the 3000 Series). One alarm sounds, they all sound; the install is done by someone who’s been trained on the kit; the certificate at the end is what Medway Council, fire risk assessors, and insurers expect to see.

What Alarms actually is

The system Aico Expert Installers fit across Gillingham is the Aico 3000 Series — current generation interlinkable mains-wired alarms with sealed 10-year batteries, available in optical smoke, heat, multi-sensor (smoke + heat), and CO variants. All interlink natively over RF (using Aico’s SmartLINK protocol) and can be hard-wire interlinked where preferred. The 3000 Series is what we recommend by default because it’s the kit we’re manufacturer-trained on, the install procedures are consistent across the range, and the alarms genuinely outperform the budget-end of the market on smoke detection sensitivity and false-alarm resistance.

When you need Alarms in Gillingham

Statutory drivers for Gillingham alarm installation: the Smoke and Carbon Monoxide Alarm (Amendment) Regulations 2022 (rental coverage), the Housing Act 2004 (HMO conditions), the Building Regulations Approved Document B (new-build requirements), and the LACORS guidance on HMO fire safety (council interpretation of HMO requirements). Voluntary drivers: home insurance discounts (some insurers offer reduced premiums for properties with mains-wired interlinked alarms), peace of mind on older property, and upgrading after a fire incident in the area or on a similar property.

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 Gillingham 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. Medway Council will specify the required grade as part of the HMO licence conditions.

Fittings and where they go

For most Gillingham domestic property, the CJA Electrical default spec is Aico 3000 Series Grade D1 alarms in this layout: optical smoke alarms in every circulation space (landing, hallway, top of stairs), heat alarms in kitchens, optical smoke alarm in main living rooms (where the BS 5839-6 risk assessment calls for it), and CO alarms in any room with a fixed combustion appliance. All alarms interlink — most commonly via Aico’s SmartLINK RF protocol so we don’t need to chase a third wire between fittings, but hard-wired interlinking is straightforward too where the property’s being recircuited anyway.

Testing schedule and remedials

Testing schedules on the systems we install: Monthly — householder press-test of each alarm. Confirms the alarm sounds and the interlink fires the others. Annually — competent-person inspection. We test each alarm, check the supply, verify the interlink, replace any end-of-life units, and issue a BS 5839-6 service record. End-of-life — Aico 3000 Series alarms have a sealed 10-year battery and a 10-year unit lifespan. End-of-life is signalled by the alarm’s status indicator a few months before expiry, giving plenty of warning to schedule replacement.

Why Gillingham property owners book CJA Electrical

The reasons Gillingham clients book us for smoke alarm work: Aico Expert Installer credential (manufacturer-trained on the 3000 Series, not a generalist who fits anything from Screwfix), local-trader trust (small operation, reputation matters, no aggressive upsell on whatever the customer actually needs), and clean documentation (BS 5839-6 certificate plus install diagram, supplied as PDF after the install). For HMO and rental clients specifically, the certificate format is what Medway Council accepts during licence renewals and enforcement visits. We’ve fitted systems across multiple HMO portfolios in Medway on that basis.

How the work runs

The flow from first contact to final certificate: Initial chat to confirm property type, number of floors, and any specific requirements (HMO licence specification, agent requirements, particular alarm grade required by an insurer). Site visit (free, normally 30 minutes) to walk through the property, identify alarm positions, and finalise the spec. Quote within a working day — fixed-price for most domestic work, capped quote for larger HMOs. Install on agreed date — single visit for most domestic; larger HMO installs may run across two visits. Demonstration and certificate at completion — householder walked through monthly test, given the logbook, supplied with the BS 5839-6 PDF.

What affects the price

Pricing splits into alarms and labour. Alarm hardware is Aico 3000 Series at trade pricing (typically £40-£60 per unit depending on type), with the labour reflecting install time, interlink commissioning, and certification. For most Gillingham domestic property the all-in fixed price is set after a site survey. Bulk pricing for HMOs and portfolio landlords reflects the economies of scale on multi-alarm installs. Annual servicing on installed systems is a separate quoted item, typically booked at the same time as the original install if requested.

FAQs

Will the alarms false-trigger on burnt toast?

Less than older alarms used to. Modern Aico optical smoke alarms have improved discrimination between cooking smoke and real fire smoke, but they’re still siting-sensitive — a smoke alarm too close to a kitchen door will occasionally false-trigger on heavy cooking. The fix is a heat alarm in the kitchen and a smoke alarm in the hallway with adequate distance. We site to BS 5839-6 spec to minimise nuisance triggers.

What standard do smoke alarms need to meet?

BS 5839-6 is the standard for domestic smoke and heat alarms. For most Gillingham homes, Grade D1 mains-wired alarms with sealed battery backup are appropriate. HMOs and larger properties may need a higher grade — we’ll advise on what your specific property requires.

Do smoke alarms need to be interlinked?

For new installations, yes — interlinked alarms (where one going off triggers all of them) are the current standard. Interlinking can be done by hard wire or by radio frequency depending on what’s easier in the property. Aico’s SmartLINK RF protocol is the default on the 3000 Series.

What about smoke alarm rules for HMOs?

HMOs have stricter requirements than ordinary rented homes — typically a higher BS 5839-6 grade with heat detection in kitchens and panel-based alerting on larger conversions. Specific requirements depend on the HMO size and the local council. We can specify and install to whatever Medway Council requires for your licence renewal.

Why Aico specifically?

Aico are the UK market leader in residential smoke alarms and the manufacturer most fire risk assessors and councils across Medway are familiar with. The 3000 Series is the current generation — interlinkable mains-wired alarms with sealed 10-year batteries — and we’re manufacturer-trained on the range as Aico Expert Installers. The kit performs reliably in real fires.
