Professional Fire Alarm Installation in London
Ajax Wireless Fire Detection Systems — Installed by SatFocus
Protect your home and business with the most advanced wireless fire alarm technology available. Dual-spectrum smoke detection, carbon monoxide sensing, and instant smartphone alerts.
Fire kills over 200 people in the UK every year, and most fatal fires start in the home. A professionally installed fire alarm system is not just a legal requirement for many properties — it is the single most effective way to protect your family, employees, and property.
At SatFocus Security, we supply and install the latest Ajax FireProtect wireless fire detection systems across Greater London. As authorised Ajax partners, we custom-design fire alarm solutions for homes, rental properties, offices, shops, and commercial buildings — with same-week installation and zero disruption.
Why Ajax Fire Alarms? The Technology That Saves Lives
Dual-Spectrum Optical Sensor
Blue and infrared LEDs measure microparticle concentration — identifies real smoke while ignoring cooking steam, vapour, and dust. Virtually zero false alarms.
HazeFlow 2 AI Algorithm
Ajax proprietary software analyses sensor data in real-time against known fire patterns. Only triggers on confirmed fire threats.
Interconnected Alarms
When one detector triggers, every fire alarm sounds within 20 seconds — 3x faster than standards require. Failsafe direct communication if hub goes offline.
Smart App Alerts
Instant push notifications on your phone. Know exactly which detector triggered, the threat type (smoke/heat/CO), and precise time — from anywhere in the world.
Up to 7 Years Battery
Pre-installed batteries with 30-day advance low-battery warnings. Mains-powered AC models available with sealed backup battery.
Full Security Integration
Connects to your existing Ajax intruder alarm, CCTV, and access control. One app, one hub, complete protection.

Fire Alarms for Landlords — Stay Legal, Avoid Fines
Under the Smoke and Carbon Monoxide Alarm (Amendment) Regulations, all landlords must install:
Smoke alarm on every floor of rental properties
CO alarm in rooms with fixed combustion appliances (gas boilers, fireplaces)
All alarms in working order at start of each tenancy
Non-compliance can result in fines up to 5,000 pounds. SatFocus provides landlord fire alarm packages with full compliance documentation.
Commercial Fire Alarm Systems — Regulatory Compliance
UK businesses must comply with the Regulatory Reform (Fire Safety) Order 2005. SatFocus installs EN 54 certified Ajax commercial fire alarm systems for offices, shops, warehouses, restaurants, schools, and healthcare facilities. Our systems integrate with your existing security infrastructure and we provide all compliance documentation.

Frequently Asked Questions
How much does fire alarm installation cost in London?
A single Ajax FireProtect detector installed starts from around 120 pounds. A full home system with multiple detectors, CO sensors, and hub integration typically costs 350-800 pounds depending on property size. Commercial systems are quoted based on your fire risk assessment.
Are Ajax fire alarms wireless?
Yes, completely wireless. Ajax fire detectors communicate via the encrypted Jeweller radio protocol with a range of up to 2,000 metres. No cables to run, no walls to drill.
How long do Ajax fire alarm batteries last?
Depending on the model, batteries last 3-7 years. The system sends low-battery alerts to your phone 30 days before replacement is needed. Mains-powered models (AC) have sealed backup batteries.
Is fire alarm installation a legal requirement?
For landlords, yes — smoke alarms on every floor and CO alarms where combustion appliances are present. For businesses, the Regulatory Reform (Fire Safety) Order 2005 requires appropriate fire detection. Homeowners are strongly advised.
Can Ajax fire alarms connect to my existing burglar alarm?
Yes, if you have an Ajax hub for your intruder alarm, fire detectors connect to the same hub instantly. They appear in the same app alongside your security sensors, cameras, and door entry systems.
Do I need a fire alarm if I already have a smoke detector?
Basic battery smoke detectors have limited coverage and no smart features. Ajax fire detectors provide interconnected alarms, instant phone notifications, CO detection, and full integration with your security system — significantly more reliable protection.
